Obviously, the described embodiments are some embodiments of the present application, not all embodiments.

In addition, the character " / " in this paper, unless otherwise specified, generally represents an "or" relationship between the associated objects before and after it.

[0138] The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0139] In the process of determining the ore prospecting target area of mineral resources by using the seismic exploration technology, 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 analyze the seismic wave data artificially. However, the process of artificially analyzing the seismic wave data and determining the ore prospecting target area is inaccurate, which leads to inaccurate determination of the coal ore prospecting target area and affects the subsequent development and utilization of coal resources.

[0140] Therefore, the present application provides an AI-based ore prospecting target area optimization evaluation method and system. By integrating seismic exploration, acoustic detection, surface monitoring and server technology, accurate evaluation of complex geological areas is realized. Seismic wave information is captured by seismic exploration equipment, and abnormal analysis can quickly lock potential mineral areas and determine reflection information accordingly. Combined with acoustic detection information, the structural characteristics of complex geological areas are further refined. Surface images collected by surface monitoring equipment are fused to provide accurate guidance for the emission of seismic waves and ensure the pertinence of exploration. According to these comprehensive information, depth seismic exploration is carried out on the target area, and the obtained exploration results can accurately reveal the distribution of mineral deposits, so as to scientifically determine the ore prospecting target area and greatly improve the ore prospecting efficiency and accuracy, providing strong technical support for mineral resource exploration.

[0141] Figure 1 An application scenario provided by the present application is shown in the figure. In the process of determining the ore prospecting target area, the method provided by the present application is applied, the seismic wave information of the seismic exploration equipment is obtained and analyzed to determine whether it is abnormal; when the seismic wave information is abnormal, the acoustic detection information of the acoustic detection equipment is obtained and analyzed to further verify the abnormal judgment result of the seismic wave, and the complex area information is determined; 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 according to the surface image and the complex area information, so as to determine the ore prospecting target area.

[0142] Specifically, the method is applied to a server in the AI-based ore-prospecting target area optimization and evaluation device, and the server in the AI-based ore-prospecting target area optimization and evaluation device can be any server. The server interacts with seismic exploration equipment, acoustic wave detection equipment, surface monitoring equipment, and mobile devices of exploration personnel. The seismic exploration equipment, acoustic wave detection equipment, and surface monitoring equipment are each multiple. The seismic exploration equipment can be equipment that uses seismic exploration technology to perform seismic exploration on an exploration area. The seismic exploration equipment can include seismic wave transmitting equipment and seismic wave receiving equipment. The seismic wave transmitting equipment is arranged in a grid arrangement in the exploration area, and the seismic wave receiving equipment is arranged in a ring arrangement in the exploration area. The acoustic wave detection equipment can be equipment that uses acoustic wave detection technology to perform acoustic wave detection on a complex geological area. The acoustic wave detection equipment can include acoustic wave transmitting equipment and acoustic wave receiving equipment. After determining the arrangement 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 according to the arrangement of the seismic wave transmitting equipment and the seismic wave receiving equipment. The grid arrangement is to arrange the seismic wave transmitting equipment and the acoustic wave transmitting equipment in the exploration area at uniform grid intervals. Because waves propagate and reflect in underground media, especially when waves encounter different medium interfaces (such as different strata), reflections occur. Arranging the receiving equipment at the edges of the exploration area can avoid complex reflections and interference that may occur in the middle of the exploration area, ensuring the quality of the wave signals. Arranging the receiving equipment at the edges of the exploration area can ensure that the receiving equipment covers all propagation paths from the center to the edges, avoiding missing due to improper equipment placement. At the same time, arranging the receiving equipment at the edges of the exploration area can ensure that seismic waves propagating along different paths are received, especially in complex geological environments. This arrangement can ensure that seismic waves propagating along certain special paths are not missed. Therefore, the ring arrangement is to arrange the seismic wave receiving equipment and the acoustic wave receiving equipment at the edges of the exploration area at uniform point intervals. The surface monitoring equipment can be equipment that monitors the surface layer of a complex geological area. The surface monitoring equipment is arranged in the exploration area according to the arrangement of the seismic wave receiving equipment. The seismic exploration equipment, acoustic wave detection equipment, and surface monitoring equipment are connected together in a wireless manner. The server obtains and analyzes seismic wave information of the seismic exploration equipment to determine whether the seismic wave is in an abnormal state. In the case that the seismic wave is in an abnormal state, the server obtains and analyzes acoustic wave detection information of the acoustic wave detection equipment to further determine whether the seismic wave is in an abnormal state, and determines complex area information of the complex geological area according to the seismic wave information and the acoustic wave detection information. The server obtains a surface image of the complex area collected by the surface monitoring equipment, and determines transmission information of the seismic wave according to the surface image and the complex area information. The server determines an ore-prospecting target area determination result according to the transmission information of the seismic wave, and sends the ore-prospecting target area determination result to the mobile device of the exploration personnel.By analyzing whether the seismic wave information is abnormal and further determining whether the seismic wave is abnormal according to the sound wave detection information, the accuracy of the determination of the abnormal seismic wave is ensured, the complex region information is determined, accurate reference basis for the determination of the subsequent seismic wave emission information is provided, and the accuracy of the determination of the ore prospecting target area is significantly improved.

[0148] Specifically, in the seismic exploration process, the seismic wave emitted by the seismic exploration device will have different reflection conditions when encountering different geological conditions. In this case, in order to ensure the accuracy of the seismic exploration, it is necessary to determine whether the seismic wave is abnormal according to the information of the seismic wave, and further determine the reflection information of the seismic wave, to provide accurate reference basis for the determination of the subsequent complex region information.

[0149] The seismic wave information collected by the seismic exploration device is obtained from the seismic exploration device. The waveform, uplink wave and downlink wave of the seismic wave are extracted from the seismic wave information. The waveform of the seismic wave is analyzed. If the waveform has phenomena such as amplitude mutation and elongated trough, the uplink wave and downlink wave are further analyzed using wave field separation technology to obtain an analysis result. According to the analysis result, it is determined whether the seismic wave information is abnormal. If the seismic wave information is abnormal, the reflection information of the seismic wave is extracted from the seismic wave information.

[0153] The complex region information can be information of a region corresponding to an abnormal seismic wave information when using a seismic exploration device to perform seismic exploration.

[0154] Specifically, in the process of using a seismic exploration device to perform seismic exploration, the geological conditions of the complex geological region will have different effects on the seismic wave. On this basis, the abnormal judgment of the seismic wave information will also be affected by the geological conditions of the complex geological region. In order to ensure the accuracy of the abnormal judgment of the seismic wave information in the above steps, the acoustic wave detection technology is used to verify the abnormal judgment of the seismic wave information, and to provide a reference basis for the determination of the subsequent emission information of the seismic wave.

[0155] The acoustic wave detection information is obtained from the acoustic wave detection device, and the frequency of the acoustic wave is extracted from the acoustic wave detection information. The reflection speed of the seismic wave is extracted from the reflection information. The reflection speed is analyzed using the reflection wave depth conversion technology to determine the depth of the complex geological region. The frequency of the acoustic wave is analyzed using the acoustic wave frequency analysis technology to obtain the rock type and geological structure of the complex geological region. The depth, rock type and geological structure of the complex geological region are included in the complex region information.

[0156] S203, obtaining a surface image of the complex geological region collected by the ground monitoring device, and determining the emission information of the seismic wave according to the complex region information and the surface image.

[0157] The surface image can be an image about the ground surface layer of the complex geological region.

[0158] The emission information can be related information of the emission angle and emission frequency of the seismic wave adjusted to ensure that the seismic wave can adapt to the exploration of the complex geological region after determining the existence of the complex geological region through the above steps.

[0159] Specifically, in the process of seismic exploration, the situation of the complex geological region is relatively complex, and the geological situation of the complex geological region will affect the emission of the seismic wave. At the same time, the situation existing in the surface layer of the complex geological region will also have a certain influence on the emission of the seismic wave. Therefore, when determining the emission information of the seismic wave, the information of the complex geological region and the surface image of the complex geological region need to be considered, so as to significantly improve the accuracy of the seismic exploration while determining the emission information of the seismic wave.

[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 a spectrum analysis technique. By analyzing the amplitudes of different frequency components, the emission frequency of the seismic wave is inferred. Using a reflectivity profile technique, the propagation path and angle of the seismic wave are determined by the reflection characteristics of the stratum, combined with wave velocity analysis techniques (for example, using the velocity difference between P waves and S waves) to calculate the emission angle of the seismic wave. The surface image is analyzed using imaging processing techniques to obtain image analysis results. According to the image analysis results, the emission frequency and emission angle are optimized to obtain a first emission frequency and a first emission angle. The first emission angle and the first emission frequency are included in the emission information.

[0161] S204, according to the emission information, the complex geological region is subjected to seismic exploration, and the exploration result is obtained. According to the exploration result, the ore prospecting target area is determined.

[0162] The exploration result can be obtained after the complex geological region is subjected to seismic exploration according to the emission information of the seismic wave. The exploration result can include the distribution area of the mineral resources, the mineral density, the target mineral content and the distribution thickness.

[0163] The ore prospecting target area can be a key exploration area aimed at finding and confirming mineral resources.

[0164] Specifically, in the process of geological exploration of the complex geological region, due to the complex situation of the complex geological region, there are certain limitations in determining the ore prospecting target area by analyzing some characteristics of the complex geological region in the process of determining the emission information of the seismic wave, thereby affecting the accuracy of the determination of the ore prospecting target area. Therefore, the complex geological region needs to be subjected to seismic exploration according to the emission information of the seismic wave, so as to ensure the accuracy of the determination of the ore prospecting target area.

[0165] The complex geological region is subjected to seismic exploration using a seismic exploration device according to the emission information determined by the above steps, and an exploration result is obtained. The distribution area of the mineral resources, the mineral density, the target mineral content and the distribution thickness are extracted from the exploration result. The distribution area, the mineral density, the target mineral content and the distribution thickness are analyzed using a mathematical analysis algorithm, and the storage capacity of the mineral resources is calculated according to formula (1):

[0166]

[0167] Wherein, S represents the storage capacity, 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 acceleration of gravity.

[0168] Before determining the ore prospecting target area, a preset reserve grade is set, and a preset reserve grade is obtained, and the preset reserve grade is divided into high, medium and low grades from large to small according to the amount of reserve. The reserve obtained by the above steps is matched with the preset reserve grade to obtain the grade corresponding to the above reserve. According to the grade corresponding to the above reserve, if the grade corresponding to the above reserve is high or medium, the exploration area corresponding to the above reserve is determined as the ore prospecting target area. If the grade corresponding to the above reserve 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 cost such as human, material and financial resources, so the exploration area corresponding to the above reserve is not determined as the ore prospecting target area.

[0169] Through the scheme, through the integration of seismic exploration, acoustic detection and surface monitoring technologies, in-depth analysis and accurate evaluation of complex geological regions are realized. The seismic exploration equipment captures and analyzes seismic wave information, quickly identifies and locks potential mineral deposit regions, and provides key clues for subsequent exploration. The acoustic detection information and the seismic wave reflection information are mutually verified, and the complex geological region information is accurately determined. The surface image provided by the surface monitoring device provides an intuitive basis for the development of seismic wave emission strategies. According to the comprehensive information, seismic exploration is implemented, the obtained exploration results accurately reveal the distribution of mineral deposits, and the ore prospecting target area is scientifically determined, which greatly improves the ore prospecting efficiency and accuracy.

[0170] In some embodiments, normal seismic wave information is obtained, and according to the normal seismic wave information, normal reflection velocity and normal reflection time are determined; according to the normal reflection velocity, the normal reflection time, a plurality of reflection times and a plurality of reflection velocities, the difference degree of a plurality of seismic waves is determined according to formula (2):

[0171]

[0172] wherein D represents the difference degree, w v represents a preset reflection velocity weight, N represents the number of reflection waves, represents the reflection velocity of the i-th reflection wave, w t represents a preset reflection time weight, V n represents the normal reflection time, represents the reflection time of the i-th reflection wave; according to the difference degree of a plurality of seismic waves, it is judged whether the seismic wave information is abnormal.

[0173] The normal seismic wave information can be information fed back after the seismic wave propagates below the ground surface without passing through any complex geological structure.

[0174] The preset reflection velocity weight can be a weight indicating the importance of the reflection velocity of the seismic wave to the difference degree. When performing formula calculation, the preset reflection velocity weight can be a specific numerical value.

[0175] The preset reflection time weight can be a specific value representing the importance of the reflection time of the seismic wave to the difference degree.

[0176] The normal reflection velocity can be a velocity representing the reflection of the seismic wave after vertical propagation under the ground surface.

[0177] The normal reflection time can be a time representing the reflection of the seismic wave after vertical propagation under the ground surface.

[0178] The reflection velocity difference can be a difference between the reflection velocity and the normal reflection velocity.

[0179] The reflection time difference can be a difference between the reflection time and the normal reflection time.

[0180] The difference degree can be a value measuring the difference between the normal reflection velocity and the normal reflection time of the seismic wave and the reflection velocity and the reflection time.

[0181] Specifically, in the process of seismic exploration, different geological conditions will have different effects on the exploration of the seismic wave. In the process of seismic exploration, in order to ensure the normal exploration of the seismic wave, the information of the seismic wave needs to be analyzed. According to the analysis result and the reflection information of the seismic wave in the exploration area, the difference degree of the seismic wave is calculated, and whether it is abnormal is judged according to the difference degree, so as to provide accurate reference basis for the determination of subsequent complex region information.

[0182] The seismic wave information of the single geological structure of the same region as the surface feature of the exploration area is obtained from the seismic exploration website, and the seismic wave information of the single geological structure of the same region as the surface feature of the exploration area is obtained from the seismic exploration website. The normal reflection velocity and the normal reflection time are extracted from the normal seismic wave information. The historical normal reflection velocity, the historical normal reflection time, the historical reflection time and the historical reflection velocity are obtained, and the historical normal reflection velocity, the historical normal reflection time, the historical reflection time and the historical reflection velocity are analyzed by using the linear regression method. The preset reflection velocity weight, the preset reflection time weight are obtained. The preset reflection velocity weight, the preset reflection time weight, the normal reflection velocity, the normal reflection time, the reflection time and the reflection velocity are analyzed by using the mathematical analysis algorithm, and the difference degree of the seismic wave is obtained according to formula (2).

[0183] In formula (2), the preset reflection velocity weight, the preset reflection time weight, the normal reflection velocity, the normal reflection time, the reflection time and the reflection velocity are analyzed by using the mathematical analysis algorithm, and the difference degree of the seismic wave is obtained according to formula (2). The absolute difference between each measured reflection velocity and the normal reflection velocity is calculated, which indicates the influence of the medium on the propagation velocity of the wave under different regions or conditions. The average of all the reflection velocity differences is taken to obtain the overall reflection velocity difference. This helps to eliminate the influence of individual measurement errors and makes the results more stable. The weight (w v ) reflects the importance of the reflection velocity in the overall difference measure. It can be adjusted according to actual conditions, for example, in certain geological conditions, the change in velocity may be more critical, so a greater weight can be given. The absolute difference between each measured reflection time and the normal reflection time is calculated. This reflects the influence of changes in the subsurface medium on the reflection time. The average difference in reflection time is calculated to make the results more representative. The weight (w t ) reflects the importance of the reflection time in the overall difference measure. If in some cases, the change in reflection time is more important than velocity, this weight can be appropriately increased.

[0184] By combining the two parts of and , D not only considers the change in reflection velocity, but also considers the change in reflection time. This comprehensive evaluation method can more comprehensively reflect the changes in the characteristics of the subsurface medium, facilitating geological analysis and resource exploration. By adjusting the weights w v and w t , the focus of the analysis can be flexibly adjusted according to specific exploration needs.

[0185] Arrange the several difference degrees obtained in the above steps in numerical order from small to large to obtain the arranged x difference degrees. Take the median of the x difference degrees obtained in the above steps to obtain the overall difference degree of the seismic wave. Before determining whether the seismic wave is abnormal, a difference degree corresponding to a level is set in advance to obtain a preset difference degree level, and the preset difference degree level is divided into high, medium, and low levels according to the size of the difference degree. Match the overall difference degree obtained in the above steps with the preset difference degree level to obtain the level corresponding to the overall difference degree. If the level corresponding to the overall difference degree is high or medium, it is determined that the seismic wave information is abnormal, and if the level corresponding to the overall difference degree is low, it is determined that the seismic wave information is not abnormal.

[0186] By the scheme, the normal reflection velocity and time are accurately determined by acquiring normal seismic wave information, to provide a basis for subsequent comparison. The two dimensions of reflection velocity and time are comprehensively considered by using a formula, and the difference degree of several seismic waves and the normal seismic wave in velocity and time is calculated, wherein the reflection velocity weight and reflection time weight are given according to actual needs, to ensure the comprehensiveness and accuracy of the evaluation. The difference degree is obtained by accumulating and averaging the deviation of each reflection wave from the normal value and multiplying the corresponding weight, which intuitively reflects the overall fluctuation of the seismic wave information. According to the size of the difference degree, it can be effectively judged whether the seismic wave information is abnormal, which provides a scientific basis for subsequent seismic exploration and ensures the timeliness and effectiveness of the evaluation.

[0187] In some embodiments, the detection depth is determined according to the emission speed and the reflection time; the position of the terrain is determined according to the detection depth and the reflection angle; the terrain inclination angle is determined according to the reflection intensity and the reflection angle based on the position of the terrain; and the complex region information is determined according to the terrain inclination angle and the sound wave detection information.

[0188] The detection depth can be the depth of the complex geological region detected by the seismic wave in the process of seismic exploration.

[0189] The emission speed can be the speed of the seismic wave at the beginning of emission in the process of seismic exploration.

[0190] The reflection angle can be the angle formed by the reflection path when the seismic wave is received by the seismic wave receiving device after encountering an obstacle to form a reflection, and the vertical line set with the seismic wave receiving device as the reference point.

[0191] The reflection intensity can be the intensity of the seismic wave acting on the reflection interface when the seismic wave encounters an obstacle to form a reflection in the process of seismic exploration.

[0192] The terrain inclination angle can be the inclination angle of the terrain below the ground surface with the vertical line set with the seismic wave receiving device as the reference point.

[0193] The position of the terrain can be the position of the terrain below the ground surface with the seismic wave receiving device as the reference point.

[0194] Specifically, in the process of seismic exploration, the terrain inclination angle and the position of the terrain of the complex geological region will affect the accuracy of the seismic exploration to some extent. When performing seismic exploration, the position of the terrain and the terrain inclination angle of the complex geological region need to be considered to ensure the accuracy of the determination of the complex region information of the complex geological region.

[0195] Because the seismic wave receiving device has multiple, the reflection angle of the seismic wave obtained by the above steps is also multiple. The detection depth is obtained by multiplying the transmission speed by the reflection time. A vertical line perpendicular to the ground is set with the seismic wave receiving device as the reference point. The reflection paths of several reflection waves are extracted from the seismic wave information, and the reflection paths are connected with the vertical line perpendicular to the ground to obtain the included angle between the vertical line and the reflection paths. The included angle between the vertical line and the reflection paths is determined as the terrain inclination angle. The first terrain contour is obtained by connecting the reflection points corresponding to the reflection paths in sequence with the vertical line perpendicular to the ground as the center. The first terrain contour is analyzed by using the centroid calculation method to obtain the position coordinates of the center point of the first terrain contour.

[0196] The space rectangular coordinate system is established with the seismic wave receiving device as the origin, and the position coordinates of the center point and the origin are analyzed by using mathematical analysis method 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 position 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, and the thickness and depth of the underground rock layers are obtained by analyzing the time and phase of the sound wave passing through different underground rock layers by using ultrasonic imaging technology. The terrain inclination angle, the thickness and depth of the underground rock layers are included in the complex region information.

[0197] Through the scheme, the complex region information is determined by comprehensively analyzing the reflection characteristics of the seismic wave under different geological conditions. The detection depth is accurately calculated by using the transmission speed and the reflection time, which provides basic data for subsequent analysis. The position of the terrain is accurately judged by combining the detection depth and the reflection angle, and the detection region is preliminarily depicted. Based on the correlation analysis of the terrain position and the reflection intensity and the reflection angle, the terrain inclination angle is accurately calculated, and the fluctuation of the terrain is revealed. Finally, the terrain inclination angle and the sound wave detection information are comprehensively analyzed to fully analyze the geological structure and the topographic features of the complex region, which provides a scientific and reliable decision basis for determining the complex region information. The whole process realizes the accurate and efficient acquisition of the complex region information.

[0198] In some embodiments, the terrain inclination angle and the terrain position of the complex geological region under the sound wave detection condition are determined according to the sound wave propagation speed and the sound wave propagation path; the terrain relative distance is determined according to the terrain position and the position of the terrain; the inclination angle difference value is determined according to the terrain inclination angle and the terrain inclination angle; the terrain position error range and the inclination angle error range are obtained, and it is judged whether the terrain relative distance and the inclination angle difference value are respectively within the terrain position error range and the inclination angle error range; if the terrain relative distance and the inclination angle difference value are respectively within the terrain position error range and the inclination angle error range, the detection depth is determined as the terrain depth; the terrain depth, the terrain inclination angle and the position of the terrain are included in the complex region information.

[0199] The sound wave propagation speed can be the speed at which the sound wave propagates in the terrain after the sound wave detection device emits the sound wave.

[0200] The sound wave propagation path can be the propagation trajectory or path of the sound wave from the sound wave emitting device to the sound wave receiving device during the sound wave detection process.

[0201] The terrain inclination angle can be the inclination angle of the terrain below the ground surface with the sound wave receiver as the reference point.

[0202] The terrain position can be the position of the terrain below the ground surface with the sound wave receiving device as the reference point.

[0203] The terrain relative distance can be the relative distance between the position of the terrain obtained under seismic exploration conditions and the position of the terrain obtained under sound wave detection conditions.

[0204] Specifically, in the case where the complex region information has been determined according to the seismic wave information, if the complex region information is determined only according to the seismic wave information, there will be a certain inaccuracy. In order to ensure the accuracy of the determination of the complex region information, it is necessary to use sound wave detection technology to further corroborate the complex region information that has been determined, so as to realize the accurate determination of the complex region information.

[0205] Before using the sound wave detection technology to corroborate the complex region information determined in the above step, because the seismic exploration device and the sound wave detection device both have independent emitting devices and receiving devices respectively. In order to ensure the reliability and rationality of the corroboration, it is necessary to arrange the seismic wave emitting device and the sound wave emitting device at the same position, and arrange the seismic wave receiving device and the sound wave receiving device at the same position.

[0206] The sound wave propagation analysis technology is used to analyze the sound wave propagation speed and the sound wave propagation path, and the terrain position and the terrain inclination angle under the sound wave detection condition are obtained. A space rectangular coordinate system is established with the seismic wave receiving device as the origin, the terrain position and the position where the terrain is located are marked in the space rectangular coordinate system, and the position where the terrain is located coordinate and the terrain coordinate are obtained. The terrain relative distance is obtained by using a mathematical analysis algorithm to analyze the terrain position coordinate and the terrain coordinate. The terrain inclination angle and the terrain inclination angle are subtracted 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 sound wave detection technology mainly determines the characteristics of the underground structure through the propagation and reflection of sound waves, but its effective range is relatively shallow, it can usually only detect strata within tens of meters to hundreds of meters, and lacks sufficient detection capability for deep underground structures (for example, deep underground rock layers or complex structures). Moreover, the propagation speed of sound waves is greatly affected by the change of medium, and in a complex underground environment, errors are easily generated. When the terrain inclination angle and the position where the terrain is located obtained under the seismic exploration condition are not much different from the data obtained by sound wave detection, it indicates that the underground geological structure characteristics detected by the two have consistency. Since the propagation and reflection of seismic waves in deep structures are more stable than sound waves, and can provide more abundant underground information, the consistency of the results of the two increases the credibility of the seismic exploration data. If the results of seismic exploration are very close to the results of sound wave detection, it means that the results of seismic exploration are more reliable and can be used as the final geological information. Therefore, if the terrain relative distance and the inclination angle difference 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. The terrain depth, the terrain inclination angle and the position where the terrain is located are included in the complex area information.

[0207] By the scheme, the terrain inclination angle and position of the complex geological area are accurately calculated using the sound wave propagation speed and path, which provides basic data for terrain analysis. By comprehensively considering the terrain position and the environment where it is located, the relative distance between terrains is determined, which helps to build the spatial structure of the geological area. At the same time, by comparing the terrain inclination angle and the inclination angle, the inclination angle difference is obtained to evaluate the inclination degree of the terrain. Further, by setting the error range of the terrain position and the inclination angle, the accuracy of the obtained data is verified. If the data meets the error range, the detection depth is regarded as the terrain depth, and the terrain depth, inclination angle and position information are integrated to form a comprehensive and accurate information description of the complex geological area.

[0208] In some embodiments, according to the sound wave detection information, the horizontal distance between any two sound wave receiving point positions and the receiving time of the sound wave received by the sound wave receiving point are determined; according to the receiving time, the receiving time difference of the receiving time is determined; according to the receiving time difference, the sound wave propagation speed and the horizontal distance, the terrain inclination angle is determined according to formula (3) calculation:

[0209]

[0210] Wherein, θ represents the terrain inclination angle, Δt represents the receiving time difference, v represents the sound wave propagation speed, 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 profile is determined; according to the terrain profile and the terrain inclination angle, the terrain position is determined.

[0211] The horizontal distance can be the relative distance formed by any two sound wave receiving devices in the horizontal plane.

[0212] The receiving time can be the time corresponding to the time when the sound wave receiving device receives the sound wave.

[0213] The sound wave reflection angle can be the angle formed by the sound wave receiving device when the sound wave emitted by the sound wave emitting device is reflected by the obstacle and received by the sound wave receiving device.

[0214] The terrain profile can be a specific profile describing the range of the terrain.

[0215] Specifically, in the process of using sound wave detection technology to verify the complex region information obtained by the above steps. Because there are multiple sound wave receiving devices, the receiving range of multiple sound wave receiving devices may exist in the case of intersection, at this time, the sound wave information received by any two or more sound wave receiving devices with receiving range intersection needs to be compared and analyzed multiple times to determine the most accurate terrain inclination angle.

[0216] The horizontal distance of any two or more sound wave receiving devices with sound wave receiving range intersection and the time when any two or more sound wave receiving devices receive the sound wave are extracted from the sound wave detection information, and the time when any two or more sound wave receiving devices receive the sound wave is determined as the sound wave receiving time. The time when any two receiving devices receive the sound wave obtained by the above steps is subtracted to obtain the receiving time difference. The receiving time difference, the sound wave propagation speed and the horizontal distance are analyzed using mathematical analysis algorithm, and the terrain inclination angle is determined according to formula (3) calculation. The sound wave propagation speed and the sound wave reflection angle are analyzed using wave front tracking technology to obtain the terrain profile. The terrain profile and the terrain inclination angle are analyzed using the inclination angle inversion model to obtain the terrain position.

[0217] Through the scheme, the horizontal distance between any two sound wave receiving points and the sound wave receiving time are accurately calculated through the sound wave detection information, and then the receiving time difference is obtained. Using these parameters and the sound wave propagation speed, the terrain inclination angle can be accurately calculated through a specific formula, which provides key data for understanding the terrain inclination degree. By analyzing the sound wave propagation path, the sound wave reflection angle is determined, which helps to depict the mode of interaction between the sound wave and the terrain. Combined with the sound wave propagation speed and the reflection angle, a preliminary image of the terrain profile can be constructed. By comprehensively analyzing the terrain profile and the terrain inclination angle, the terrain position can be accurately determined, thereby fully revealing the terrain features 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 the propagation speed, the phase, the amplitude, the number of reflection interfaces and the reflection time according to formula (4):

[0219]

[0220] wherein A represents the terrain area, N represents the number of reflection interfaces, V represents the propagation speed, t i represents the reflection time of the i th reflection interface, A v represents the amplitude, C represents a preset adjustment constant, and φ i represents the phase of the i th reflection interface; the emission angle of the seismic wave is determined according to the terrain area and the terrain inclination angle; the degree of relief of the seismic exploration area is determined according to the surface image; the first emission angle is obtained by adjusting the emission angle according to the degree of relief, and the first emission angle is included in the emission information.

[0221] The number of reflection times can be the number corresponding to the time when the seismic wave receiving device receives the seismic wave when the seismic wave encounters an obstacle to form a reflection.

[0222] The preset adjustment constant can be a numerical value for adjusting the influence degree of the amplitude on the terrain area.

[0223] The number of reflection interfaces can be the number corresponding to the interfaces of the complex geological region that reflect the seismic wave.

[0224] The propagation speed can be the speed corresponding to the propagation of the seismic wave in the complex geological region after emission.

[0225] The degree of relief can be a numerical value for measuring the height of the surface of the complex geological region.

[0226] The emission angle can be the angle corresponding to the seismic wave emitted by the seismic exploration device during seismic exploration.

[0227] The terrain area can be the area formed by the extent of the complex geological region.

[0228] Specifically, in the process of using the seismic exploration equipment to conduct seismic exploration on the complex geological region, the relief degree of the surface of the complex geological region and the phase, amplitude and other characteristics of the seismic wave will affect the emission angle of the seismic wave to a certain extent, therefore, the amplitude, phase of the seismic wave and the relief degree of the surface of the complex geological region need to be considered 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 speed and reflection time of the historical seismic wave are obtained, and the linear regression method is used to analyze the phase, amplitude, number of reflection interfaces, propagation speed and reflection time of the historical seismic wave, to obtain a preset adjustment constant. The mathematical analysis algorithm is used to analyze the preset adjustment constant, propagation speed, phase, amplitude, number of reflection interfaces and reflection time, and the terrain area is obtained according to formula (4).

[0230] In formula (4), the terrain area is calculated as follows: represents the depth of the seismic wave reaching the i-th reflection interface. Specifically, V is the propagation speed of the seismic wave (m / s), and t i is the reflection time (s) from the source emission to the interface. Since the seismic wave needs to go back and forth, it needs to be divided by 2.

[0231] is used to normalize the amplitude A v . A 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, and 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 calculating the area can be more accurately reflected. The 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 cosine value of the phase φ i of the wave, indicating the influence of the phase on the characteristics of the reflected wave. The change of the phase may reflect the geometry of the underground structure or the propagation characteristics of the wave. The influence of the phase lies in the change of the propagation path and reflection characteristics of the wave. When the phase is positive, the reflected wave may be coherent with the incident wave, and when the phase is negative, the reflected wave may be interfered. This factor can help identify the influence of interface changes on the terrain, thereby affecting the calculation of the area.

[0233] The combination of depth, amplitude and phase can more comprehensively reflect the characteristics of the underground structure. Each part takes into account important factors that affect the characteristics of the fold. 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 terrain inclination angle are analyzed using a digital elevation model to obtain the emission angle of the seismic wave. The degree of relief is analyzed using a mathematical analysis algorithm to obtain the degree of relief. Before determining the first emission angle, the degree of relief and its corresponding angle adjustment value are preset to obtain a preset angle adjustment set. The degree of relief obtained in the above steps is matched with the preset angle adjustment set to obtain the angle adjustment value corresponding to the degree of relief obtained in the above steps. The emission angle is adjusted according to the angle adjustment value corresponding to the degree of relief obtained in the above steps to obtain the first emission angle, and the first emission angle is included in the emission information.

[0235] Through the scheme, the number of underground reflection interfaces is determined by the number of reflection times, and then the terrain area is accurately calculated by 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, improving the accuracy of terrain area estimation. In combination with the terrain area and the inclination angle, the emission angle of the seismic wave is preliminarily determined, providing directional guidance for seismic exploration. The emission angle is finely adjusted by analyzing the relief of the surface image to obtain a first emission angle that is more consistent with the actual terrain. The adjusted emission angle is included in the emission information, providing a more scientific and reasonable detection path for seismic exploration.

[0236] In some embodiments, according to the surface image, the surface soil type is determined; according to the surface soil type, the porosity of the surface soil is determined; the layout information of the receiving device is obtained and analyzed to determine the arrangement interval of the receiving device; according to the porosity and the arrangement interval, the emission frequency of the seismic wave is determined, and the emission frequency is included in the emission information.

[0237] The surface soil type can be the type corresponding to the surface soil of the complex geological region.

[0238] The porosity can be a numerical value that measures the number of pores in the surface soil per unit area of the complex geological region.

[0239] The arrangement interval can be the interval distance determined when the seismic receiving device is arranged.

[0240] The layout information can be information indicating the arrangement of the seismic wave receiving device.

[0241] The emission frequency can be the emission frequency of the seismic wave per unit time.

[0242] Specifically, in the process of seismic exploration using a seismic exploration device, the surface features of the complex geological area and the layout information of the seismic wave receiving device will affect the determination of the transmission frequency of the seismic wave, thereby affecting the accuracy of the seismic exploration. Therefore, when determining the transmission frequency of the seismic wave, the layout of the seismic wave receiving device and the surface features need to be considered to ensure the accuracy of the transmission frequency.

[0243] The surface image is analyzed using an image analysis algorithm to obtain a surface soil type. According to the surface soil type, the porosity of the surface soil is determined. The layout information of the seismic wave receiving device is obtained, and the arrangement interval of the seismic wave receiving device is extracted from the layout information. The porosity and the arrangement interval 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 the scheme, the type of the surface soil layer is accurately identified by analyzing the surface image, providing a reliable basis for subsequent determination of the porosity. According to the type of the surface soil layer, the porosity is accurately determined, which helps to understand the physical properties of the soil layer and has an important influence on the propagation of the seismic wave. By obtaining and analyzing the layout information of the receiving device, the arrangement interval of the receiving device is reasonably determined to ensure accurate reception of the seismic wave signal. The transmission frequency of the seismic wave is scientifically determined by comprehensively considering the information of the porosity and the arrangement interval, so as to optimize the effect of the seismic exploration, and the key parameter is included in the transmission information, which provides more accurate operation guidance for the seismic exploration.

[0245] In some embodiments, a preset soil type density and a preset soil type wave speed are obtained, and a soil layer density and a first propagation speed are determined according to the surface soil type, the preset soil type wave speed, and the soil type density. The transmission frequency of the seismic wave is determined according to formula (5) according to the soil layer density, the porosity, the arrangement interval, the first propagation speed, the terrain depth, and the first transmission angle:

[0246]

[0247] wherein f represents the transmission frequency, k represents a preset frequency adjustment constant, q represents the soil layer density, θ represents the first transmission angle, M represents the terrain depth, v0 represents the first propagation speed, n represents a preset soil layer property index, d represents the arrangement interval, and h represents the terrain depth.

[0248] The preset soil type wave speed can be the propagation speed of the seismic wave in the soil layer in the case of no porosity in the soil layer corresponding to the soil type.

[0249] The preset soil type density can be a preset soil layer density corresponding to the soil type.

[0250] The first propagation speed can be the propagation speed of the seismic wave in the case of no porosity of the soil layer.

[0251] The preset frequency adjustment constant can be a value that affects the determination of the seismic wave transmission frequency.

[0252] The soil layer density can be the tightness of the surface soil layer of the complex geological area.

[0253] Specifically, in determining the transmission frequency of the seismic wave, the surface soil layer density and porosity of the complex geological area will affect the determination of the transmission frequency of the seismic wave to some extent, thereby affecting the accurate determination of the transmission frequency of the seismic wave, and further affecting the accuracy of the seismic exploration. Therefore, the surface soil layer density and porosity of the complex geological area need to be considered to ensure the accuracy of the seismic exploration.

[0254] The preset soil layer type density and the preset soil layer type wave speed are obtained, the surface soil layer types obtained in the above step are matched with the preset soil layer type density and the preset soil layer type wave speed respectively, the soil layer density and the propagation speed corresponding to the above surface soil layer types are obtained, and the propagation speed corresponding to the above surface soil layer types is determined as the first propagation speed. The historical soil layer density, historical porosity, historical arrangement interval, historical seismic wave propagation speed, historical terrain depth and historical seismic wave transmission angle are obtained, and the linear regression method is used to analyze the historical soil layer density, historical porosity, historical arrangement interval, historical seismic wave propagation speed, historical terrain depth and historical seismic wave transmission angle, to obtain a preset frequency adjustment constant. The soil layer density, porosity, arrangement interval, first propagation speed, terrain depth and first transmission angle are analyzed using a mathematical analysis algorithm, and the transmission frequency of the seismic wave is obtained according to formula (5).

[0255] In formula (5), the ratio of wave speed to receiver interval Indicates the frequency component of wave propagation per unit distance. High wave speed and small interval will result in high frequency, and vice versa. The influence of soil layer density (1-q): the greater the porosity, the more voids in the soil layer, the smaller the effective density of the soil layer, and thus the wave speed decreases, resulting in a decrease in transmission frequency. This reflects the influence of the physical properties of the soil layer on the seismic wave. Deep terrain will have a greater impact on wave propagation, resulting in a decrease in wave speed and frequency. This factor is particularly important in complex geological conditions.

[0256] The cosine value of the transmission angle cos(θ): the transmission angle has a direct impact on the propagation path of the wave. A larger angle means that the wave needs to pass through more complex geological structures, which can result in a decrease in frequency. The constant k needs to be calibrated through experimental data and the formula needs to be adjusted to adapt to specific conditions under different geological conditions.

[0257] By the scheme, the soil layer density and the first propagation speed are accurately calculated in combination with the preset soil layer type density and wave speed and the actual surface soil layer type, thereby providing a basic parameter for determination of the transmission frequency. The transmission frequency of the seismic wave is scientifically calculated by applying a specific formula in comprehensive consideration of multiple factors such as the soil layer density, porosity, receiving device arrangement spacing, first propagation speed, terrain depth and first transmission angle. This step not only ensures the accuracy and rationality of the transmission frequency, but also effectively improves the efficiency and accuracy of the seismic exploration. The transmission frequency setting in the seismic exploration is provided with comprehensive and detailed operation guidance by integrating multiple information.

[0258] In some embodiments, according to the surface image, the surface uniformity of the complex geological region is determined; meteorological data is acquired, and according to the meteorological data, the environmental humidity and the environmental temperature of the complex geological region are determined; according to the transmission speed, the medium type of the complex geological region is determined; according to the P-wave speed and the medium type, the medium density of the complex geological region is determined; according to the surface uniformity, the medium density, the environmental humidity and the environmental temperature, the transmission intensity of the seismic wave is determined according to formula (6) calculation:

[0259]

[0260] wherein I represents the transmission intensity, t represents a preset proportion constant, i represents the medium density, H represents the environmental humidity, k T represents a preset temperature weight, T represents the environmental temperature, and E represents the surface uniformity; the transmission intensity is included in the transmission information.

[0261] The surface uniformity can be a numerical value for measuring the uniformity of the distribution of surface objects of the complex geological region.

[0262] The preset proportion constant can be a coefficient that affects the determination of the transmission intensity.

[0263] The medium density can be a density degree corresponding to the geological morphology between the complex geological region and the ground surface.

[0264] The transmission intensity can be a numerical value for measuring the energy of the seismic wave released by the seismic wave transmission device.

[0265] Specifically, in the process of seismic exploration, the intensity of the seismic wave is affected by the surface soil layer and the terrain medium, thereby causing a certain attenuation of the seismic wave, leading to inaccurate detection of the seismic wave, and further affecting the determination of the ore prospecting target area. Therefore, the influence of the surface soil layer and the terrain medium needs to be considered to provide a reference basis for the determination of the transmission intensity of the seismic wave.

[0266] Before determining the emission intensity, the medium types corresponding to all possible seismic wave emission velocities are obtained, and the medium types corresponding to all possible seismic wave emission velocities are integrated to obtain a preset velocity type set. The emission velocity obtained in the above step is matched with the preset velocity type set to obtain the medium type corresponding to the above emission velocity. All possible medium types and their corresponding bulk moduli are obtained, and all possible medium types and their corresponding bulk moduli are integrated to obtain a preset type modulus set. The medium type obtained in the above step is matched with the preset type modulus set to obtain the bulk modulus corresponding to the medium type obtained in the above step. The P-wave velocity of the seismic wave is extracted from the seismic wave information. The bulk modulus and the P-wave velocity are analyzed using a mathematical analysis algorithm to obtain the medium density. The surface image is analyzed using an image analysis algorithm to obtain the surface uniformity. The meteorological data is obtained, and the environmental humidity and the environmental temperature of the complex geological region are extracted from the meteorological data. The surface uniformity, the medium density, the environmental humidity, and the environmental temperature are analyzed using a mathematical analysis algorithm, and the emission intensity of the seismic wave is determined according to formula (6).

[0267] In formula (6), the energy output characteristics of different sources and the differences in measurement conditions can be considered by using a preset proportionality constant t. The higher the density, the greater the mass of the medium, which can generally propagate seismic waves more effectively. It is directly related to wave speed and energy propagation, increasing the overall emission intensity. An increase in humidity usually leads to soil saturation, affecting 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, and the propagation efficiency of the wave is the lowest, and the emission intensity decreases 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 speed. In general, an increase in temperature increases the wave speed and enhances the emission intensity.

[0268] (1+k T ·T)·E in formula (6) represents the enhancing effect of temperature on emission intensity. k T is a temperature influence coefficient, and its specific value is determined by experimental data and is used to quantify the influence of temperature change on emission intensity. E represents the uniformity of the surface, and its value range is [0, 1]. 1 represents a completely uniform surface, and 0 represents an extremely uneven surface. The uniformity of the surface has a significant impact on the propagation efficiency of the seismic wave: a uniform surface can more effectively transmit the seismic wave and enhance the emission intensity. An uneven surface can cause scattering and attenuation of the wave, reducing the emission intensity.

[0269] Through the scheme, the surface uniformity of the seismic exploration area is analyzed through the surface image, and a terrain basis is provided for the determination of the emission intensity. The meteorological data are acquired and analyzed, the environmental humidity and temperature are accurately calculated, and the influence of the environmental factors on the seismic wave propagation is further considered. According to the emission speed and the longitudinal wave speed, the medium type of the complex geological area is accurately judged, and the medium density is determined accordingly. The emission intensity of the seismic wave is scientifically calculated through the application of a specific formula by comprehensively considering multiple factors such as the surface uniformity, the medium density, the environmental humidity and the temperature, so as to ensure that the emission intensity meets the exploration requirements and is suitable for the specific environmental conditions. This step not only improves the flexibility of the seismic exploration, but also enhances the reliability of the exploration results.
