Before mining mineral resources, using seismic exploration technology to determine the target area for mineral resource exploration can effectively ensure the accuracy of the target area for mineral resource exploration, thereby providing a basic reference for the subsequent development and utilization of mineral resources.
[0003] When using seismic exploration technology to determine the target area for prospecting mineral resources, the existing seismic exploration technology has certain limitations in the exploration of complex geological conditions. In the process of exploring complex geological conditions, it is necessary to manually analyze the seismic wave data. However, there are inaccuracies in the process of manually analyzing the seismic wave data and determining the target area for prospecting, which leads to inaccurate determination of coal prospecting targets and affects the subsequent development and utilization of coal resources. Summary of the invention

[0010] Through this solution, by integrating seismic exploration, acoustic wave detection and surface monitoring technologies, in-depth analysis and accurate evaluation of complex geological areas are achieved. Seismic exploration equipment captures and analyzes seismic wave information, quickly identifies and locks potential mineral deposits, and provides key clues for subsequent exploration. Acoustic wave detection information and seismic wave reflection information corroborate each other to accurately determine the information of complex geological areas. The surface images provided by surface monitoring equipment provide an intuitive basis for the formulation of seismic wave emission strategies. Based on comprehensive information, seismic exploration is carried out, and the exploration results obtained accurately reveal the distribution of mineral deposits and scientifically determine the prospecting target area, which greatly improves the efficiency and accuracy of prospecting.

[0013] The degree of difference of the plurality of seismic waves is determined according to the normal reflection velocity, the normal reflection time, the plurality of reflection times and the plurality of reflection velocities, and is calculated according to the following formula:
[0014]
[0015] Where D represents the degree of difference, w v represents the preset reflection speed weight, N represents the number of reflected waves, represents the reflection speed of the i-th reflected wave, w t Represents the preset reflection time weight, V n represents the normal reflection time, represents the reflection time of the i-th reflected wave;
[0016] Whether the seismic wave information is abnormal is determined based on the degree of difference between the plurality of seismic waves.
[0017] Through this solution, by obtaining normal seismic wave information, the normal reflection speed and time are accurately determined to provide a benchmark for subsequent comparisons. The formula comprehensively considers the two dimensions of reflection speed and time, and calculates the degree of difference between several seismic waves and normal seismic waves in speed and time. Reflection speed weights and reflection time weights are assigned according to actual needs to ensure the comprehensiveness and accuracy of the assessment. By accumulating and averaging the deviation of each reflection wave from the normal value, and then multiplying it by the corresponding weight, the degree of difference is obtained, which intuitively reflects the overall fluctuation of the seismic wave information. According to the size of the difference, it is possible to effectively judge whether the seismic wave information is abnormal, which provides a scientific basis for subsequent seismic exploration and ensures the timeliness and effectiveness of the assessment.

The detection depth is accurately calculated using the emission speed and reflection time to provide basic data for subsequent analysis. The location of the terrain is accurately determined by combining the detection depth and reflection angle, and a preliminary depiction of the detection area is achieved. Based on the correlation analysis of the terrain position and the reflection intensity and reflection angle, the terrain inclination angle is accurately calculated to reveal the ups and downs of the terrain. Finally, the terrain inclination angle and acoustic wave detection information are combined to comprehensively analyze the geological structure, geomorphological characteristics and other information of complex areas, providing a scientific and reliable decision-making basis for the determination of complex regional information. The entire process achieves accurate and efficient acquisition of complex regional information.

This step provides basic data for terrain analysis. The relative distance between terrains is determined by comprehensive consideration of the terrain position and the environment in which it is located, which helps to construct the spatial structure of the geological area. At the same time, the terrain inclination and the tilt angle are compared to obtain the tilt angle difference to evaluate the tilt degree of the terrain. Further, the accuracy of the obtained data is verified by setting the error range of the terrain position and the tilt angle. If the data meets the error range, the detection depth is regarded as the terrain depth, and the terrain depth, tilt angle and location information are integrated to form a comprehensive and accurate information description of the complex geological area.

Using these parameters and the sound wave propagation speed, the terrain inclination can be accurately calculated through a specific formula. This step provides key data for understanding the degree of terrain inclination. The sound wave reflection angle is determined by analyzing the sound wave propagation path, which helps to depict the pattern of interaction between sound waves and terrain. Combining the sound wave propagation speed and reflection angle, a preliminary image of the terrain contour can be constructed. Combining the information of terrain contour and terrain inclination, the terrain location can be accurately determined, thereby fully revealing the terrain characteristics of the detection area and providing strong support for geological exploration.

[0050] Through this solution, the number of underground reflection interfaces is determined by the number of reflection times, and then the terrain area is accurately calculated through a specific formula using the propagation speed, phase, amplitude, number of reflection interfaces and reflection time. This step effectively integrates the multi-dimensional information of seismic wave reflection and improves the accuracy of terrain area estimation. Combined with the terrain area and tilt angle, the emission angle of the seismic wave is preliminarily determined, providing directional guidance for seismic exploration.

According to the type of surface soil layer, its porosity is accurately determined. This step helps to understand the physical properties of the soil layer and has an important impact on the propagation of seismic waves.

[0139] When using seismic exploration technology to determine the target area for prospecting mineral resources, the existing seismic exploration technology has certain limitations in the exploration of complex geological conditions. In the process of exploring complex geological conditions, it is necessary to manually analyze the seismic wave data. However, there are inaccuracies in the process of manually analyzing the seismic wave data and determining the target area for prospecting, which leads to inaccurate determination of coal prospecting targets and affects the subsequent development and utilization of coal resources.

[0141] Figure 1 A schematic diagram of an application scenario provided for the present application. When determining a prospecting target area, the method provided by the present application is applied to obtain and analyze the seismic wave information of the seismic exploration equipment to determine whether it is abnormal; when the seismic wave information is abnormal, the abnormal judgment result of the seismic wave is further supported by obtaining and analyzing the sound wave detection information of the sound wave detection equipment to determine the complex area information; the surface image of the complex geological area collected by the surface monitoring equipment is obtained, and the emission information of the seismic wave is determined based on the surface image and the complex area information, thereby determining the prospecting target area.
[0142] Specifically, the method provided in the present application is applied to the server in the above-mentioned AI-based prospecting target area optimization evaluation device. The server in the AI-based prospecting target area optimization evaluation device can be any server, and the server interacts with seismic exploration equipment, acoustic wave detection equipment, surface monitoring equipment and mobile devices of the prospectors. There are multiple seismic exploration equipment, acoustic wave detection equipment and surface monitoring equipment respectively. The seismic exploration equipment can be a device that uses seismic exploration technology to conduct seismic exploration in the exploration area, and the seismic exploration equipment can include seismic wave transmitting equipment and seismic wave receiving equipment. The seismic wave transmitting equipment is arranged in the exploration area in a grid layout, and the seismic wave receiving equipment is arranged in the exploration area in a ring layout. The acoustic wave detection equipment can be a device that uses acoustic wave detection technology to conduct acoustic wave detection in complex geological areas, and the acoustic wave detection equipment can include acoustic wave transmitting equipment and acoustic wave receiving equipment. After determining the layout of the seismic wave transmitting equipment and the seismic wave receiving equipment, the acoustic wave transmitting equipment and the acoustic wave receiving equipment are arranged respectively according to the layout of the above-mentioned seismic wave transmitting equipment and the seismic wave receiving equipment. The above-mentioned grid layout method is to arrange the seismic wave transmitting equipment and the sound wave transmitting equipment in the exploration area at uniform mesh intervals. Since the wave will propagate and reflect in the underground medium, especially when the wave encounters different medium interfaces (such as different strata), reflection will occur. Arranging the receiving equipment at the edge of the exploration area can avoid the complex reflection and interference that may be generated in the middle part of the exploration area, and ensure the quality of the wave signal. Arranging the receiving equipment at the edge of the exploration area can ensure that the receiving equipment can cover all propagation paths from the center to the edge, avoiding missed connections due to improper equipment location. At the same time, arranging the receiving equipment at the edge of the exploration area can ensure the reception of seismic waves propagated by different paths, especially in complex geological environments. This layout method can ensure that seismic waves propagated from certain special paths will not be missed. Therefore, the above-mentioned ring layout method is to arrange the seismic wave receiving equipment and the sound wave receiving equipment at the edge of the exploration area at uniform point intervals. The surface monitoring equipment can be a device for monitoring the surface layer of the ground in a complex geological area, and the surface monitoring equipment is arranged in the exploration area in the above-mentioned arrangement method of the seismic wave receiving equipment. Seismic exploration equipment, acoustic wave detection equipment and surface monitoring equipment are connected together by wireless connection. The server determines whether the seismic wave is in an abnormal state by acquiring and analyzing the seismic wave information of the seismic exploration equipment; when the seismic wave is in an abnormal state, the server acquires and analyzes the acoustic wave detection information of the acoustic wave detection equipment to further determine whether the seismic wave is in an abnormal state, and determines the complex area information of the complex geological area based on the seismic wave information and the acoustic wave detection information; the server acquires the surface image of the complex area collected by the surface monitoring equipment, and determines the emission information of the seismic wave based on the surface image and the complex area information; the server determines the result of the prospecting target area based on the emission information of the seismic wave, and sends the result of the prospecting target area to the mobile device of the prospector.By analyzing whether the seismic wave information is abnormal and further determining whether the seismic wave is abnormal based on the sound wave detection information, the accuracy of the seismic wave abnormality judgment is ensured while determining the complex regional information, providing an accurate reference basis for the determination of subsequent seismic wave emission information, thereby significantly improving the accuracy of the determination of the prospecting target area.

[0158] The emission information may be information related to the emission angle and frequency of the seismic waves adjusted to ensure that the seismic waves can adapt to the exploration of the complex geological area after the existence of the complex geological area is determined through the above steps.
[0159] Specifically, during seismic exploration, the situation in complex geological areas is relatively complex. The geological conditions in complex geological areas will affect the emission of seismic waves. At the same time, the conditions existing in the ground surface of complex geological areas will also have a certain impact on the emission of seismic waves. Therefore, when determining the emission information of seismic waves, it is necessary to consider the information of complex geological areas and the surface images of complex geological areas, so as to significantly improve the accuracy of seismic exploration while determining the emission information of seismic waves.
[0160] The time domain signal of the seismic wave is extracted from the seismic wave information, and the frequency characteristics are extracted from the time domain signal of the seismic wave using spectrum analysis technology.

[0161] S204. Conduct seismic exploration in complex geological areas based on the transmission information to obtain exploration results, and determine the prospecting target area based on the exploration results.
[0162] The exploration results can be the results obtained after seismic exploration of complex geological areas based on the transmission information of seismic waves. The exploration results can include the distribution area of mineral resources, mineral density, target mineral content and distribution thickness.
[0163] A prospecting target area may be a key exploration area aimed at finding and confirming mineral resources.
[0164] Specifically, in the process of geological exploration in complex geological areas, due to the complex situations in complex geological areas, in the process of determining the emission information of seismic waves, there are certain limitations in determining the target area for prospecting by analyzing certain characteristics of the complex geological area, which affects the accuracy of determining the target area for prospecting. Therefore, it is necessary to conduct seismic exploration in complex geological areas based on the emission information of seismic waves to ensure the accuracy of determining the target area for prospecting.
[0165] Use seismic exploration equipment to conduct seismic exploration in complex geological areas according to the transmission information determined in the above steps to obtain exploration results. Extract the distribution area, mineral density, target mineral content and distribution thickness of mineral resources from the exploration results. Use mathematical analysis algorithms to analyze the distribution area, mineral density, target mineral content and distribution thickness, and calculate according to formula (1) to obtain the reserves of mineral resources:
[0166]
[0167] Among them, S represents the reserve volume, A represents the distribution area, h represents the distribution thickness, p represents the mineral density, C represents the target mineral content, and g represents the gravitational acceleration.
[0168] Before determining the prospecting target area, a reserve level is pre-set to obtain a preset reserve level, which is divided into high, medium and low levels according to the amount of reserves. The reserves obtained in the above steps are matched with the preset reserve level to obtain the level corresponding to the above reserves. According to the level corresponding to the above reserves, if the level corresponding to the above reserves is high or medium, the exploration area corresponding to the above reserves is determined as a prospecting target area. If the level corresponding to the above reserves is low, it means that the value of developing and utilizing the mineral resources in the exploration area is not enough to meet the development costs such as manpower, material resources and financial resources consumed by the development, so the exploration area corresponding to the above reserves is not determined as a prospecting target area.
[0169] Through this solution, by integrating seismic exploration, acoustic wave detection and surface monitoring technologies, in-depth analysis and accurate evaluation of complex geological areas are achieved. Seismic exploration equipment captures and analyzes seismic wave information, quickly identifies and locks potential mineral deposits, and provides key clues for subsequent exploration. Acoustic wave detection information and seismic wave reflection information corroborate each other to accurately determine the information of complex geological areas. The surface images provided by surface monitoring equipment provide an intuitive basis for the formulation of seismic wave emission strategies. Based on comprehensive information, seismic exploration is carried out, and the exploration results obtained accurately reveal the distribution of mineral deposits and scientifically determine the prospecting target area, which greatly improves the efficiency and accuracy of prospecting.
[0170] In some embodiments, normal seismic wave information is obtained, and a normal reflection velocity and a normal reflection time are determined according to the normal seismic wave information; and the degree of difference of the seismic waves is determined according to the normal reflection velocity, the normal reflection time, the reflection times and the reflection velocities by calculating according to formula (2):
[0171]
[0172] Among them, D represents the degree of difference, w v represents the preset reflection speed weight, N represents the number of reflection waves, represents the reflection speed of the i-th reflected wave, w t Represents the preset reflection time weight, V n Indicates the normal reflection time, Indicates the reflection time of the i-th reflection wave; determines whether the seismic wave information is abnormal based on the degree of difference between several seismic waves.
[0173] Normal seismic wave information may be information fed back indicating that seismic waves propagate below the surface without passing through any complex geological structures.
[0174] The preset reflection velocity weight may be a degree of importance of the reflection velocity of the seismic wave to the degree of difference. When performing formula calculation, the preset reflection velocity weight may be a specific value.
[0175] The preset reflection time weight may be a value indicating the importance of the reflection time of the seismic wave to the degree of difference. When performing formula calculation, the preset reflection time weight may be a specific value.
[0176] The normal reflection velocity may be a velocity indicating the reflection of seismic waves after propagating vertically below the surface of the earth.
[0177] The normal reflection time may be the time taken for a seismic wave to reflect after propagating vertically below the surface of the earth.
[0178] The reflection velocity difference may be a difference between the reflection velocity and a normal reflection velocity.
[0179] The reflection time difference may be a difference between the reflection time and a normal reflection time.
[0180] The degree of difference may be a numerical value measuring the difference between the normal reflection velocity and normal reflection time of the seismic wave and the reflection velocity and reflection time.
[0181] Specifically, during seismic exploration, different geological conditions will have different effects on the exploration of seismic waves. In order to ensure the normal exploration of seismic waves, it is necessary to analyze the information of seismic waves. According to the analysis results and the reflection information of seismic waves in the exploration area, the difference degree of seismic waves is calculated, and it is judged whether it is abnormal according to the difference degree, so as to provide an accurate reference for the determination of subsequent complex regional information.
[0182] Seismic wave information of a single geological structure in the same area as the surface features of the exploration area is obtained from the seismic exploration website, and the seismic wave information of a single geological structure in the same area as the surface features of the exploration area is determined as normal seismic wave information. The normal reflection velocity and normal reflection time are extracted from the normal seismic wave information. The historical normal reflection velocity, the historical normal reflection time, the historical several reflection times and the historical several reflection velocities are obtained, and the historical normal reflection velocity, the historical normal reflection time, the historical several reflection times and the historical several reflection velocities are analyzed by the linear regression method to obtain the preset reflection velocity weight and the preset reflection time weight. The preset reflection velocity weight, the preset reflection time weight, the normal reflection velocity, the normal reflection time, the several reflection times and the several reflection velocities are analyzed by the mathematical analysis algorithm, and the difference degree of several seismic waves is obtained according to the calculation of formula (2).
[0183] In formula (2), The absolute difference between each measured reflection velocity and the normal reflection velocity is calculated, which indicates the effect of the medium on the wave propagation speed in different areas or conditions. It is used to take the average of all reflected wave velocity differences to obtain the overall degree of difference in reflection velocity. This helps to eliminate the influence of individual measurement errors and make the results more stable. v ): This weight reflects the importance of reflection velocity in the overall difference metric. It can be adjusted according to actual conditions. For example, under certain geological conditions, the change in velocity may be more critical, so a larger weight can be given. It is used to calculate the absolute difference between each measured reflection time and the normal reflection time. This reflects the impact of changes in the underground medium on the propagation time of the reflected wave. Used to calculate the average difference in reflection time to make the results more representative. (w t ) reflects the importance of reflection time in the overall difference measurement. If in some cases, the change of reflection time is more important than speed, this weight can be appropriately increased.
[0184] By and Combining these two parts, D not only takes into account the change of reflection speed, but also the change of reflection time. This comprehensive evaluation method can more comprehensively reflect the changes in the characteristics of underground media, which is convenient for geological analysis and resource exploration. v and w t , the focus of analysis can be flexibly adjusted according to specific exploration needs.
[0185] Arrange the several degrees of difference obtained in the above steps in numerical order from small to large to obtain x degrees of difference after arrangement. Take the median of the x degrees of difference obtained in the above steps to obtain the overall degree of difference of several seismic waves. Before judging whether the seismic wave is abnormal, pre-set a level corresponding to the degree of difference to obtain a preset degree of difference level, and the preset degree of difference level is divided into high, medium and low levels according to the size of the degree of difference. Match the overall degree of difference obtained in the above steps with the preset degree of difference level to obtain the level corresponding to the overall degree of difference. If the level corresponding to the overall degree of difference is high or medium, it is judged that the seismic wave information is abnormal. If the level corresponding to the overall degree of difference is low, it is judged that the seismic wave information is not abnormal.
[0186] Through this solution, by obtaining normal seismic wave information, the normal reflection speed and time are accurately determined to provide a benchmark for subsequent comparisons. The formula comprehensively considers the two dimensions of reflection speed and time, and calculates the degree of difference between several seismic waves and normal seismic waves in speed and time. Reflection speed weights and reflection time weights are assigned according to actual needs to ensure the comprehensiveness and accuracy of the assessment. By accumulating and averaging the deviation of each reflection wave from the normal value, and then multiplying it by the corresponding weight, the degree of difference is obtained, which intuitively reflects the overall fluctuation of the seismic wave information. According to the size of the difference, it is possible to effectively judge whether the seismic wave information is abnormal, which provides a scientific basis for subsequent seismic exploration and ensures the timeliness and effectiveness of the assessment.
[0187] In some embodiments, the detection depth is determined based on the emission speed and reflection time; the location of the terrain is determined based on the detection depth and reflection angle; based on the location of the terrain, the inclination angle of the terrain is determined based on the reflection intensity and reflection angle; and complex area information is determined based on the terrain inclination angle and acoustic wave detection information.
[0188] The detection depth can be the depth of a complex geological area detected by seismic waves during seismic exploration.
[0189] The emission velocity can be the velocity of seismic waves at the beginning of emission during seismic exploration.
[0190] The reflection angle may be the angle formed by a reflection path formed when a seismic wave is reflected by an obstacle and then received by a seismic wave receiving device during seismic exploration and a vertical line set with the seismic wave receiving device as a reference point.
[0191] Reflection intensity can be the intensity of the effect of seismic waves on the reflection interface when the seismic waves encounter obstacles and form reflections during seismic exploration.
[0192] The terrain inclination angle may be the inclination angle formed by the terrain below the surface and a vertical line set with the seismic wave receiving device as a reference point.
[0193] The location of the terrain may be the location of the terrain below the surface of the earth, with the seismic wave receiving device as a reference point.
[0194] Specifically, during seismic exploration, information such as the terrain inclination angle and the location of the terrain in a complex geological area will affect the accuracy of seismic exploration to a certain extent. When conducting seismic exploration, it is necessary to consider the location of the terrain and the inclination angle of the terrain in a complex geological area to ensure the accuracy of the determination of complex regional information in the complex geological area.
[0195] Because there are multiple seismic wave receiving devices, there are also multiple reflection angles of seismic waves obtained in the above steps. Multiply the transmission speed by the reflection time to obtain the detection depth. Set a vertical line perpendicular to the ground with the seismic wave receiving device as the reference point. Extract the reflection paths of several reflected waves from the seismic wave information, connect the several reflected wave paths with the vertical line perpendicular to the ground, and obtain the angles between the several vertical lines and the reflected wave paths. The angles between the several vertical lines and the reflected wave paths are determined as the terrain inclination angle. With the vertical line perpendicular to the ground as the center, connect the several reflection points corresponding to the several reflection paths in sequence to obtain the first terrain contour. Use the centroid calculation method to analyze the first terrain contour to obtain the center point position coordinates of the first terrain contour.
[0196] Taking the seismic wave receiving device as the origin, a spatial rectangular coordinate system is established. The coordinates of the center point and the origin are analyzed using mathematical analysis methods to obtain the relative position of the origin and the center point. The relative position of the origin and the center point is determined as the location of the terrain. The time and phase of the sound wave passing through different underground rock layers are extracted from the sound wave detection information. The time and phase of the sound wave passing through different underground rock layers are analyzed using ultrasonic imaging technology to obtain the thickness and depth of the underground rock layer. The terrain inclination angle, thickness and depth of the underground rock layer are included in the complex area information.
[0197] Through this solution, the reflection characteristics of seismic waves under different geological conditions are comprehensively analyzed to determine the information of complex areas. The detection depth is accurately calculated using the emission speed and reflection time to provide basic data for subsequent analysis. The location of the terrain is accurately determined by combining the detection depth and reflection angle, and a preliminary depiction of the detection area is achieved. Based on the correlation analysis of the terrain position and the reflection intensity and reflection angle, the terrain inclination angle is accurately calculated to reveal the ups and downs of the terrain. Finally, the terrain inclination angle and acoustic wave detection information are combined to comprehensively analyze the geological structure, geomorphological characteristics and other information of complex areas, providing a scientific and reliable decision-making basis for the determination of complex regional information. The entire process achieves accurate and efficient acquisition of complex regional information.
[0198] In some embodiments, the terrain inclination and terrain position of a complex geological area under acoustic wave detection conditions are determined based on the sound wave propagation speed and the sound wave propagation path; the terrain relative distance is determined based on the terrain position and the location of the terrain; the tilt angle difference is determined based on the terrain inclination and the terrain tilt angle; the terrain position error range and the tilt angle error range are obtained to determine whether the terrain relative distance and the tilt angle difference are within the terrain position error range and the tilt angle error range, respectively; if the terrain relative distance and the tilt angle difference are within the terrain position error range and the tilt angle error range, respectively, the detection depth is determined as the terrain depth; the terrain depth, terrain tilt angle and the location of the terrain are included in the complex area information.
[0199] The sound wave propagation speed may be the speed at which the sound wave propagates in the terrain after the sound wave detection device transmits the sound wave.
[0200] The sound wave propagation path may be the propagation track or path of the sound wave from the sound wave transmitting device to the sound wave receiving device during the sound wave detection process.
[0201] The terrain inclination angle can be the tilt angle formed by the terrain below the surface with the sound wave receiver as a reference point.
[0202] The terrain position may be the position of the terrain below the surface of the earth, with the sound wave receiving device as a reference point.
[0203] The terrain relative distance may be the relative distance formed between the terrain position obtained under seismic exploration conditions and the terrain position obtained under acoustic wave detection conditions.
[0204] Specifically, in the case where the complex regional information has been determined based on the seismic wave information, there will be certain inaccuracies if the complex regional information is determined only based on the seismic wave information. In order to ensure the accuracy of the determination of the complex regional information, it is necessary to use the acoustic wave detection technology to further verify the complex regional information that has been determined, so as to achieve accurate determination of the complex regional information.
[0205] Before using the acoustic wave detection technology to verify the complex regional information determined in the above steps, because both the seismic exploration equipment and the acoustic wave detection equipment have independent transmitting equipment and receiving equipment, in order to ensure the reliability and rationality of the verification, the seismic wave transmitting equipment and the acoustic wave transmitting equipment need to be arranged at the same location, and the seismic wave receiving equipment and the acoustic wave receiving equipment need to be arranged at the same location.
[0206] The acoustic wave propagation analysis technology is used to analyze the acoustic wave propagation speed and acoustic wave propagation path to obtain the terrain position and terrain inclination under the acoustic wave detection conditions. With the seismic wave receiving device as the origin, a spatial rectangular coordinate system is established, and the terrain position and the terrain position are marked in the spatial rectangular coordinate system to obtain the terrain position coordinates and terrain coordinates. The terrain position coordinates and terrain coordinates are analyzed using a mathematical analysis algorithm to obtain the terrain relative distance. The terrain inclination angle is subtracted from the terrain inclination angle to obtain the inclination angle difference. The terrain position error range and the inclination angle error range are obtained. The terrain relative distance and the inclination angle difference are matched with the terrain position error range and the inclination angle error range, respectively, to determine whether the terrain relative distance and the inclination angle difference are within the terrain position error range and the inclination angle error range, respectively. Since the acoustic wave detection technology mainly determines the characteristics of the underground structure through the propagation and reflection of the sound wave, its range of action is relatively shallow, and it can usually only detect strata of tens to hundreds of meters, and lacks sufficient detection capabilities for deep underground structures (for example, deep underground rock strata or complex structures). Moreover, the propagation speed of sound waves is greatly affected by the change of the medium, and it is easy to produce errors in complex underground environments. When the terrain inclination angle and the location of the terrain obtained under seismic exploration conditions are not much different from the data obtained by acoustic detection, this indicates that the underground geological structure characteristics detected by the two are consistent. Since the propagation and reflection of seismic waves in deep structures are more stable than acoustic waves and can provide richer underground information, the consistency of the two results increases the credibility of seismic exploration data. If the results of seismic exploration are very close to those of acoustic detection, it means that the seismic exploration results may be more reliable and can be used as the final geological information. Therefore, if the relative distance and inclination angle difference of the terrain are within the terrain position error range and the inclination angle error range, respectively, the detection depth obtained in the above steps is determined as the terrain depth. And the terrain depth, terrain inclination angle and terrain location are included in the complex regional information.
[0207] Through this solution, the speed and path of sound wave propagation are used to accurately calculate the terrain inclination and position of complex geological areas. This step provides basic data for terrain analysis. The relative distance between terrains is determined by comprehensive consideration of the terrain position and the environment in which it is located, which helps to construct the spatial structure of the geological area. At the same time, the terrain inclination and the tilt angle are compared to obtain the tilt angle difference to evaluate the tilt degree of the terrain. Further, the accuracy of the obtained data is verified by setting the error range of the terrain position and the tilt angle. If the data meets the error range, the detection depth is regarded as the terrain depth, and the terrain depth, tilt angle and location information are integrated to form a comprehensive and accurate information description of the complex geological area.
[0208] In some embodiments, according to the acoustic wave detection information, the horizontal distance between any two acoustic wave receiving points and the receiving time when the acoustic wave receiving points receive the acoustic wave are determined; according to the receiving time, the receiving time difference of the receiving time is determined; according to the receiving time difference, the acoustic wave propagation speed and the horizontal distance, the terrain inclination is determined by calculation according to formula (3):
[0209]
[0210] Among them, θ represents the terrain inclination, Δt represents the receiving time difference, v represents the sound wave propagation speed, and d represents the horizontal distance; according to the sound wave propagation path, the sound wave reflection angle is determined; according to the sound wave propagation speed and the sound wave reflection angle, the terrain contour is determined; according to the terrain contour and the terrain inclination, the terrain position is determined.
[0211] The horizontal distance may be the relative distance formed by any two sound wave receiving devices on the horizontal plane.
[0212] The receiving time may be the time corresponding to when the sound wave receiving device receives the sound wave.
[0213] The sound wave reflection angle may be an angle formed between the sound wave emitted by the sound wave transmitting device and the sound wave receiving device when the sound wave is received by the sound wave receiving device after encountering an obstacle and being reflected.
[0214] A terrain profile may be a specific profile that describes the extent of the terrain.
[0215] Specifically, in the process of using the acoustic wave detection technology to verify the complex area information obtained in the above steps, because there are multiple acoustic wave receiving devices, the receiving ranges of multiple acoustic wave receiving devices may overlap, and at this time, it is necessary to compare and analyze the acoustic wave information received by any two or more acoustic wave receiving devices with overlapping receiving ranges for multiple times to determine the most accurate terrain inclination.
[0216] Extract the horizontal distance between any two or more sound wave receiving devices with overlapping sound wave receiving ranges and the moment when any two or more sound wave receiving devices receive the sound waves from the sound wave detection information, and determine the moment when any two or more sound wave receiving devices receive the sound waves as the sound wave receiving time. Subtract the moment when any two receiving devices receive the sound waves obtained in the above steps to obtain the receiving time difference. Use a mathematical analysis algorithm to analyze the receiving time difference, the sound wave propagation speed and the horizontal distance, and calculate according to formula (3) to determine the terrain inclination. Use wavefront tracking technology to analyze the sound wave propagation speed and the sound wave reflection angle to obtain the terrain contour. Use the inclination inversion model to analyze the terrain contour and terrain inclination to obtain the terrain position.
[0217] Through this solution, the horizontal distance between any two sound wave receiving points and the sound wave reception time can be accurately calculated through the sound wave detection information, and then the reception time difference can be obtained. Using these parameters and the sound wave propagation speed, the terrain inclination can be accurately calculated through a specific formula. This step provides key data for understanding the degree of terrain inclination. The sound wave reflection angle is determined by analyzing the sound wave propagation path, which helps to depict the pattern of interaction between sound waves and terrain. Combining the sound wave propagation speed and reflection angle, a preliminary image of the terrain contour can be constructed. Combining the information of terrain contour and terrain inclination, the terrain location can be accurately determined, thereby fully revealing the terrain characteristics of the detection area and providing strong support for geological exploration.
[0218] In some embodiments, the number of reflection interfaces is determined according to the number of reflection times; the terrain area is determined according to formula (4) based on the propagation speed, phase, amplitude, number of reflection interfaces and reflection time:
[0219]
[0220] Where A represents the terrain area, N represents the number of reflection interfaces, V represents the propagation speed, and t i represents the reflection time of the i-th reflection interface, A v represents the amplitude, C represents the preset adjustment constant, φ i Represents the phase of the i-th reflection interface; determines the emission angle of the seismic wave according to the terrain area and the terrain inclination angle; determines the terrain undulation degree of the seismic exploration area according to the surface image; adjusts the emission angle according to the terrain undulation degree to obtain the first emission angle, and incorporates the first emission angle into the emission information.
[0221] The reflection time quantity may be the quantity corresponding to the time that the seismic wave is received by the seismic wave receiving device when the seismic wave encounters an obstacle to be reflected and is received by the seismic wave receiving device.
[0222] The preset adjustment constant may be a value used to adjust the degree of influence of the amplitude on the terrain area.
[0223] The number of reflection interfaces may be the number of interfaces corresponding to the reflection of seismic waves in a complex geological region.
[0224] The propagation velocity can be the speed at which seismic waves propagate in complex geological areas after being emitted.
[0225] The relief degree can be a numerical value to measure the height of the surface of a complex geological area.
[0226] The emission angle may be the angle corresponding to the seismic waves emitted by the seismic exploration equipment during seismic exploration.
[0227] The terrain area can be the area formed by the scope of a complex geological region.
[0228] Specifically, in the process of using seismic exploration equipment to conduct seismic exploration in complex geological areas, the undulation of the surface of the complex geological area and the phase, amplitude and other characteristics of the seismic waves will affect the emission angle of the seismic waves to a certain extent. Therefore, it is necessary to consider the amplitude, phase and undulation of the seismic waves and the undulation of the surface of the complex geological area to ensure the accuracy of the emission angle.
[0229] The number of reflection times is extracted from the seismic wave information, and the number of reflection times is determined as the number of reflection interfaces. The phase, amplitude, number of reflection interfaces, propagation velocity and reflection time of the historical seismic waves are obtained, and the phase, amplitude, number of reflection interfaces, propagation velocity and reflection time of the historical seismic waves are analyzed using the linear regression method to obtain the preset adjustment constant. The preset adjustment constant, propagation velocity, phase, amplitude, number of reflection interfaces and reflection time are analyzed using a mathematical analysis algorithm, and the terrain area is calculated according to formula (4).
[0230] In formula (4), represents the depth at which the seismic wave reaches the i-th reflection interface. Specifically, V is the propagation velocity of the seismic wave (m / s), and t i It is the reflection time (in seconds) from the source to the interface. Since seismic waves need to travel back and forth, it needs to be divided by 2.
[0231] For amplitude A v Perform normalization. v is the amplitude of the reflected wave, reflecting the intensity of the reflected wave; C is a constant used to adjust the influence of the amplitude. The amplitude reflects the impedance difference and reflection characteristics of the medium. The larger the amplitude, the stronger the interface reflection, which may have a greater impact on the characteristics of the fold. Through this weighting factor, the relative importance of the amplitude in the calculation of the area can be more accurately reflected. This formula ensures that the contribution of the amplitude to the area will not be exaggerated due to extreme values.
[0232] cos(φ i ) is the phase of the wave φ i The cosine of , represents the effect of phase on the characteristics of the reflected wave. Changes in phase may reflect the geometry of the underground structure or the propagation characteristics of the wave. The effect of phase is the change in the propagation path and reflection characteristics of the wave. When the phase is positive, the reflected wave may be coherent with the incident wave, while when the phase is negative, the reflected wave may interfere. This factor can help identify the impact of interface changes on the terrain, thereby affecting the calculation of area.
[0233] The combination of depth, amplitude and phase can more fully reflect the characteristics of the underground structure. Each part takes into account the important factors that affect the characteristics of the folds. Using weighting factors and phase information, the influence of outliers on the results can be reduced, ensuring more accurate calculation results.
[0234] The terrain area and the terrain inclination angle are analyzed using a digital elevation model to obtain the emission angle of the seismic wave. The surface image is analyzed using a mathematical analysis algorithm to obtain the degree of terrain undulation. Before determining the first emission angle, the degree of terrain undulation and its corresponding angle adjustment value are pre-set to obtain a preset angle adjustment set. The terrain undulation obtained in the above steps is matched with the preset angle adjustment set to obtain the angle adjustment value corresponding to the terrain undulation obtained in the above steps. According to the angle adjustment value corresponding to the terrain undulation obtained in the above steps, the emission angle is adjusted to obtain the first emission angle, and the first emission angle is included in the emission information.
[0235] Through this solution, the number of underground reflection interfaces is determined by the number of reflection times, and then the terrain area is accurately calculated through a specific formula using the propagation speed, phase, amplitude, number of reflection interfaces and reflection time. This step effectively integrates the multi-dimensional information of seismic wave reflection and improves the accuracy of terrain area estimation. Combined with the terrain area and tilt angle, the emission angle of the seismic wave is preliminarily determined, providing directional guidance for seismic exploration. The terrain undulations are analyzed through surface images, and the emission angle is finely adjusted to obtain a first emission angle that is more in line with the actual terrain. The adjusted emission angle is incorporated into the emission information, providing a more scientific and reasonable detection path for seismic exploration.
[0236] In some embodiments, the type of surface soil layer is determined based on the surface image; the porosity of the surface soil layer is determined based on the type of surface soil layer; the layout information of the receiving equipment is obtained and analyzed to determine the layout spacing of the receiving equipment; the transmission frequency of the seismic wave is determined based on the porosity and the layout spacing, and the transmission frequency is incorporated into the transmission information.
[0237] The surface soil layer type may be a type corresponding to the surface soil layer of a complex geological area.
[0238] Porosity can be a numerical value that measures the number of pores per unit area in the surface soil layer of a complex geological area.
[0239] The arrangement spacing may be the spacing distance determined when the seismic receiving devices are arranged.
[0240] The deployment information may be information indicating the deployment of the seismic wave receiving device.
[0241] The emission frequency can be the number of times seismic waves are emitted per unit time.
[0242] Specifically, in the process of using seismic exploration equipment for seismic exploration, the surface characteristics of complex geological areas and the layout information of seismic wave receiving equipment will affect the determination of the transmission frequency of seismic waves, thereby affecting the accuracy of seismic exploration. Therefore, when determining the transmission frequency of seismic waves, it is necessary to consider the layout of the seismic wave receiving equipment and the surface characteristics to ensure the accuracy of the transmission frequency.
[0243] The surface image is analyzed using an image analysis algorithm to obtain the surface soil layer type. Based on the surface soil layer type, the porosity of the surface soil layer is determined. The layout information of the seismic wave receiving device is obtained, and the layout spacing of the seismic wave receiving device is extracted from the layout information. The porosity and layout spacing are analyzed using a mathematical analysis algorithm to obtain the transmission frequency of the seismic wave, and the transmission frequency of the seismic wave is included in the transmission information.
[0244] Through this solution, the type of surface soil layer can be accurately identified by analyzing the surface image, providing a reliable basis for the subsequent determination of porosity. According to the type of surface soil layer, its porosity is accurately determined. This step helps to understand the physical properties of the soil layer and has an important impact on the propagation of seismic waves. By obtaining and analyzing the layout information of the receiving equipment, the layout spacing of the receiving equipment is reasonably determined to ensure the accurate reception of seismic wave signals. The transmission frequency of seismic waves is scientifically determined by combining the information of porosity and layout spacing to optimize the seismic exploration effect, and this key parameter is incorporated into the transmission information, providing more accurate operational guidance for seismic exploration.
[0245] In some embodiments, a preset soil layer type density and a preset soil layer type wave velocity are obtained, and the soil layer density and the first propagation velocity are determined according to the surface soil layer type, the preset soil layer type wave velocity and the soil layer type density; and the emission frequency of the seismic wave is determined according to the soil layer density, porosity, arrangement spacing, first propagation velocity, terrain depth and first emission angle, calculated according to formula (5):
[0246]
[0247] Among them, f represents the transmission frequency, k represents the preset frequency adjustment constant, q represents the soil density, θ represents the first transmission angle, M represents the terrain depth, v0 represents the first propagation speed, n represents the preset soil property index, d represents the layout spacing, and h represents the terrain depth.
[0248] The preset soil layer type wave velocity may be the propagation velocity of the seismic wave in the soil layer corresponding to the soil layer type when the soil layer has no porosity.
[0249] The preset soil layer type density may be a soil layer density corresponding to a preset soil layer type.
[0250] The first propagation velocity may be a propagation velocity of seismic waves when the soil layer has no porosity.
[0251] The preset frequency adjustment constant may be a value that affects the determination of the seismic wave transmission frequency.
[0252] Soil density can be the compactness of surface soil layers in complex geological areas.
[0253] Specifically, when determining the transmission frequency of seismic waves, the density and porosity of the surface soil layer in complex geological areas will affect the determination of the transmission frequency of seismic waves to a certain extent, thereby affecting the precise determination of the transmission frequency of seismic waves, and further affecting the accuracy of seismic exploration. Therefore, it is necessary to consider the density and porosity of the surface soil layer in complex geological areas to ensure the accuracy of seismic exploration.
[0254] Obtain the preset soil layer type density and the preset soil layer type wave velocity, match the surface soil layer type obtained in the above steps with the preset soil layer type density and the preset soil layer type wave velocity, respectively, obtain the soil layer density and propagation velocity corresponding to the above surface soil layer type, and determine the propagation velocity corresponding to the above surface soil layer type as the first propagation velocity. Obtain the historical soil layer density, historical porosity, historical layout spacing, historical seismic wave propagation velocity, historical terrain depth and historical seismic wave emission angle, use the linear regression method to analyze the historical soil layer density, historical porosity, historical layout spacing, historical seismic wave propagation velocity, historical terrain depth and historical seismic wave emission angle, and obtain the preset frequency adjustment constant. Use a mathematical analysis algorithm to analyze the soil layer density, porosity, layout spacing, first propagation velocity, terrain depth and first emission angle, and calculate according to formula (5) to obtain the emission frequency of the seismic wave.
[0255] In formula (5), the ratio of the wave speed to the distance between the receiving devices is Indicates the frequency component of wave propagation per unit distance. High wave velocity and small spacing will lead to high frequency, and vice versa. Influence of soil density (1-q): The greater the porosity, the more voids there are in the soil layer, and the smaller the effective density of the soil layer, so the wave velocity decreases, resulting in a lower transmission frequency. This reflects the influence of the physical properties of the soil layer on seismic waves. Deep terrain will have a greater impact on wave propagation, resulting in a decrease in wave velocity and frequency. This factor is particularly important under complex geological conditions.
[0256] Cosine of the launch angle, cos(θ): The launch angle has a direct impact on the wave propagation path. A larger angle means that the wave needs to pass through more complex geological structures, which may lead to a decrease in frequency. Experimental data is needed to calibrate the constant k and adjust the formula to suit the specific conditions under different geological conditions.
[0257] Through this solution, the soil layer density and the first propagation velocity are accurately calculated by combining the preset soil layer type density and wave velocity, as well as the actual surface soil layer type, providing basic parameters for determining the transmission frequency. Taking into account multiple factors such as soil layer density, porosity, receiving equipment layout spacing, first propagation velocity, terrain depth, and first transmission angle, the transmission frequency of seismic waves is scientifically calculated by applying a specific formula. This step not only ensures the accuracy and rationality of the transmission frequency, but also effectively improves the efficiency and accuracy of seismic exploration. By integrating various information, comprehensive and detailed operational guidance is provided for the setting of transmission frequency in seismic exploration.
[0258] In some embodiments, the surface uniformity of the complex geological region is determined based on the surface image; meteorological data is obtained, and the ambient humidity and ambient temperature of the complex geological region are determined based on the meteorological data; the medium type of the complex geological region is determined based on the emission velocity; the medium density of the complex geological region is determined based on the longitudinal wave velocity and the medium type; and the emission intensity of the seismic wave is determined based on the surface uniformity, medium density, ambient humidity and ambient temperature, calculated according to formula (6):
[0259]
[0260] Where I represents the emission intensity, t represents the preset proportional constant, i represents the medium density, H represents the ambient humidity, and k T Represents the preset temperature weight, T represents the ambient temperature, and E represents the surface uniformity; the emission intensity is included in the emission information.
[0261] Surface uniformity can be a numerical value that measures the uniformity of the distribution of surface objects in complex geological areas.
[0262] The preset proportionality constant may be a coefficient that affects the determination of the emission intensity.
[0263] Medium density can be the density corresponding to the geological morphology between the complex geological area and the surface.
[0264] The emission intensity can be a numerical value that measures the magnitude of the seismic wave energy released by the seismic wave transmitting equipment.
[0265] Specifically, during seismic exploration, the intensity of seismic waves will be affected by the surface soil layer and terrain medium, which will cause a certain attenuation of the seismic waves, resulting in the inability to accurately detect the seismic waves, which in turn affects the determination of the prospecting target area. Therefore, it is necessary to consider the influence of the surface soil layer and terrain medium to provide a reference for the determination of the seismic wave emission intensity.
[0266] Before determining the emission intensity, obtain the medium types corresponding to all possible seismic wave emission velocities, integrate all possible medium types corresponding to the seismic wave emission velocities, and obtain a preset velocity type set. Match the emission velocity obtained in the above step with the preset velocity type set to obtain the medium type corresponding to the above emission velocity. Obtain all possible medium types and their corresponding bulk moduli, integrate all possible medium types and their corresponding bulk moduli, and obtain a preset type modulus set. Match the medium type obtained in the above step with the preset type modulus set to obtain the bulk modulus corresponding to the medium type obtained in the above step. Extract the longitudinal wave velocity of the seismic wave from the seismic wave information. Use a mathematical analysis algorithm to analyze the bulk modulus and the longitudinal wave velocity to obtain the medium density. Use an image analysis algorithm to analyze the surface image to obtain the surface uniformity. Obtain meteorological data, and extract the ambient humidity and ambient temperature of the complex geological area from the meteorological data. Use a mathematical analysis algorithm to analyze the surface uniformity, medium density, ambient humidity and ambient temperature, and calculate according to formula (6) to determine the emission intensity of the seismic wave.
[0267] Among them, in formula (6), by presetting the proportional constant t, the differences in energy output characteristics and measurement conditions of different seismic sources can be taken into account. The higher the density, the greater the mass of the medium, which can usually propagate seismic waves more effectively. It is directly related to wave velocity and energy propagation, and increases the overall emission intensity. Increased humidity usually leads to soil saturation, which affects the propagation of seismic waves. This term in the formula reflects the weakening effect of humidity on emission intensity: when the humidity is 100%, the soil is saturated, the wave propagation efficiency is the lowest, and the emission intensity is reduced to 0. When the humidity is 0%, the soil is dry and the emission intensity is not affected. Temperature changes affect the physical properties of the medium, especially the elastic modulus and wave velocity. Generally speaking, increased temperature increases wave velocity and enhances emission intensity.
[0268] (1+k in formula (6) T ·T)·E represents the enhancement effect of temperature on emission intensity. T is the temperature influence coefficient. The specific value needs to be determined through experimental data and is used to quantify the impact of temperature changes on emission intensity. E represents the uniformity of the surface, and its value range is [0,1]. 1 means that the surface is completely uniform, and 0 means that it is extremely non-uniform. The uniformity of the surface has a significant impact on the propagation efficiency of seismic waves: a uniform surface can transmit seismic waves more effectively and enhance the emission intensity. An non-uniform surface may cause scattering and attenuation of waves, reducing the emission intensity.
[0269] Through this solution, the surface uniformity of the seismic exploration area is analyzed through surface images, providing a topographic basis for determining the emission intensity. Meteorological data is obtained and analyzed to accurately calculate the environmental humidity and temperature, further considering the impact of environmental factors on seismic wave propagation. According to the emission speed and longitudinal wave velocity, the medium type in complex geological areas is accurately judged, and the medium density is determined accordingly. Combining multiple factors such as surface uniformity, medium density, environmental humidity and temperature, the emission intensity of seismic waves is scientifically calculated by applying specific formulas to ensure that the emission intensity meets both exploration needs and specific environmental conditions. This step not only improves the flexibility of seismic exploration, but also enhances the reliability of exploration results.
