Description

Technical Field

[0001] This invention belongs to the field of mineral exploration technology, specifically a method for rapidly delineating gold deposits based on geophysical and geochemical data analysis. Background Technology

[0002] In the field of gold resource exploration, the integrated application of geophysical exploration (Geophysical) and geochemical exploration (Geochemical) techniques for predicting and delineating prospecting targets has become a recognized and highly efficient method. Geophysical methods infer geological structures and mineralization spaces by detecting differences in the physical properties of underground rocks and ores, while geochemical methods indicate deep mineralization information by systematically analyzing the elemental distribution and anomalies in the surface medium. With the development of field analysis equipment, especially the application of technologies such as X-ray fluorescence spectrometers, it has become possible to rapidly and non-destructively acquire multi-element geochemical data in the field, providing the technical conditions for real-time acquisition and preliminary fusion analysis of geophysical and geochemical data at the exploration site. Against this backdrop, how to systematically integrate and optimize these techniques to construct a rapid and coherent exploration workflow from regional scanning to precise target location is an important direction for current technological development in this field.

[0003] However, the aforementioned technologies often suffer from the following drawbacks: First, the techniques are isolated and time-consuming. Geophysical, geochemical, and geological work are often conducted in stages, with poor coordination between each stage and asynchronous data interpretation. This results in a lengthy decision-making chain from anomaly discovery to drilling verification, leading to low overall exploration efficiency. Second, the reliability of the target area is insufficient. Traditional methods often rely on single technical means (such as relying solely on geochemical anomalies or isolated geophysical anomalies) for inference. The lack of information dimensions makes multiple interpretations prominent, resulting in a low success rate of drilling verification and increased exploration risks and costs. Third, cost control is rudimentary. Traditional geochemical work usually requires all field samples to be sent back to the laboratory for unified analysis, failing to conduct rapid on-site screening of massive amounts of samples, resulting in a large amount of unnecessary analysis costs and time delays. Finally, there is a lack of effective feedback and optimization loops. The "prediction" and "verification" stages in the traditional process are disconnected, making it difficult to use drilling results in a timely and systematic manner to correct and guide the deployment of previous geophysical and geochemical work, resulting in slow technological iteration and experience accumulation.

[0004] Therefore, this invention provides a rapid gold ore delineation method based on geophysical and geochemical data analysis. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A rapid gold ore delineation method based on geophysical and geochemical data analysis, comprising the following steps:

[0007] A1. Collect and digitize geological maps, mineral maps, remote sensing images, and historical exploration data within the work area to establish an initial GIS database;

[0008] A2. Samples were collected using aquatic sediment measurement techniques and sent to the laboratory for multi-element analysis. Through statistical analysis and mapping, a comprehensive geochemical anomaly zone dominated by gold was delineated at the regional scale.

[0009] A3. Set up a dense soil monitoring network in the anomaly area, use X-ray fluorescence detection device to conduct multi-element detection, obtain the content data of key elements and generate on-site maps, and focus the areal anomalies to several specific surface element concentration centers.

[0010] A4. Deploy ground geophysical exploration equipment in the concentration center to detect the spatial distribution, occurrence and burial depth of low resistivity, high polarizability bodies or ore-controlling structures related to mineralization, so as to achieve a perspective from surface chemical anomalies to underground physical structures.

[0011] A5. On the GIS 3D platform, the surface element anomalies, underground geophysical anomalies and known geological structures are spatially integrated and coupled to establish a "geo-physical-geochemical" integrated model.

[0017] A34. The drive roller squeezes the air inside the elastic air cushion. The compressed air enters the elastic sidewall through the guide hole and is then sprayed out evenly through the spray hole, blowing the soil at the edge of the conveyor belt towards the middle of the conveyor belt.

[0018] A35. Using an X-ray fluorescence analyzer, the soil passing over the conveyor belt is subjected to fluorescence analysis to detect the characteristic X-rays released after the material is excited, and to identify the elemental composition contained therein.

[0019] Preferably, the X-ray fluorescence detection device in step A3 includes a trolley; the trolley is equipped with a dust cover; and the dust cover contains a transmission roller, a conveyor belt, and an X-ray fluorescence analyzer.

[0020] The drive rollers are provided in a pair and rotatably connected inside the dust cover; one of the drive rollers is driven by a motor.

[0021] The conveyor belt is sleeved on the surface of a pair of drive rollers; a set of soil-boring plates are evenly hinged to the outside of the conveyor belt; an elastic element is provided between the soil-boring plates and the conveyor belt; a bucket is provided at the end of the soil-boring plate; a set of shovel teeth are evenly distributed at the bottom of the bucket;

[0022] The X-ray fluorescence analyzer is positioned above the conveyor belt; the X-ray fluorescence analyzer is used to perform fluorescence analysis on the soil passing over the surface of the conveyor belt.

[0023] Preferably, an installation frame is provided on the outside of the dust cover, and the installation frame is fixedly connected to the trolley; an electric telescopic rod is fixedly connected between the installation frame and the dust cover; and a rubber pad is fixedly connected to the lower side of the dust cover.

[0024] Preferably, elastic sidewalls are fixedly connected to both sides of the conveyor belt.

[0025] Preferably, an elastic air cushion is fixedly connected to the inner side of the conveyor belt; both the elastic air cushion and the elastic sidewall are designed as hollow structures and are interconnected through guide holes; a set of spray holes are evenly distributed on the side of the elastic sidewall closest to the conveyor belt.

[0027] Preferably, the elastic element includes a connecting cylinder and a connecting rod; the connecting cylinder and the connecting rod are respectively hinged to the conveyor belt and the soil sampling plate; a piston is slidably and sealed inside the connecting cylinder, and the piston is fixedly connected to the connecting rod; a spring is fixedly connected between the piston and the connecting cylinder.

[0028] Preferably, a pressure plate is hinged inside the bucket; a hollow elastic telescopic block is fixedly connected between the pressure plate and the soil-boring plate; the cavity of the connecting cylinder near the soil-boring plate is connected to the elastic telescopic block through a conduit.

[0029] Preferably, the chamber of the connecting cylinder near the conveyor belt is connected to the bucket via a second conduit.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The present invention discloses a rapid gold prospecting method based on geophysical and geochemical data analysis, which constructs an efficient, economical, and logically closed-loop rapid exploration decision-making system. Its core lies in adopting a collaborative logic of "geochemical exploration first, followed by geophysical exploration," and using an X-ray fluorescence detection device as the on-site decision-making hub, achieving a rapid transition from large-area scanning to precise drilling target location. This method significantly improves exploration efficiency and prediction reliability by rapidly focusing the target area through on-site geochemical exploration and verifying deep structures with geophysical probes. It optimizes cost allocation through on-site screening and continuously optimizes the process based on a complete "prediction-verification-feedback" chain. Ultimately, this invention integrates dispersed technical means into an organically collaborative exploration "production line," significantly improving the overall efficiency and accuracy of mineral prospecting.

[0032] 2. The present invention describes a rapid gold ore delineation method based on geophysical and geochemical data analysis. A trolley is moved to a designated position, and a motor drives the transmission rollers and conveyor belt to rotate. The conveyor belt then drives multiple soil-collecting plates on its surface to circulate. When a soil-collecting plate rotates to the bottom, its bucket contacts the soil, allowing it to scoop up and store the soil. When the soil-collecting plate rotates to the top, the soil in the bucket falls onto the surface of the conveyor belt under gravity. An X-ray fluorescence analyzer is used to perform fluorescence analysis on the soil passing over the conveyor belt surface, detecting the characteristic X-rays released after the substances are excited, thus rapidly and non-destructively identifying the elemental composition contained within.

[0033] 3. The rapid gold ore delineation method based on geophysical and geochemical data analysis described in this invention involves the following steps: When the elastic air cushion inside the conveyor belt moves to the drive roller, the drive roller compresses the elastic air cushion, compressing the air inside. The compressed air enters the hollow structure of the elastic sidewall through the guide hole and is then evenly sprayed out through the nozzle. The sprayed airflow forms an air curtain on both sides of the conveyor belt. On the one hand, it blows soil samples from the edge of the conveyor belt toward the middle of the conveyor belt so that they can be fully captured by the X-ray fluorescence analyzer. On the other hand, the airflow can also clean the soil powder adhering to the surface of the elastic sidewall, preventing long-term accumulation from affecting the protective effect of the sidewall. At the same time, the hollow structure design also reduces the weight of the overall components and reduces the load on the conveyor belt during operation. Attached Figure Description

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] like Figure 1 As shown, the present invention provides a rapid gold deposit delineation method based on geophysical and geochemical data analysis, comprising the following steps:

[0046] A1. Collect and digitize geological maps, mineral maps, remote sensing images, and historical exploration data within the work area to establish an initial GIS database;

[0047] A2. Samples were collected using aquatic sediment measurement techniques and sent to the laboratory for multi-element analysis. Through statistical analysis and mapping, a comprehensive geochemical anomaly zone dominated by gold was delineated at the regional scale.

[0048] A3. Set up a dense soil monitoring network in the anomaly area, use X-ray fluorescence detection device to conduct multi-element detection, obtain the content data of key elements (arsenic, antimony, etc.) and generate on-site maps, and focus the areal anomalies to several specific surface element concentration centers.

[0049] A4. Deploy ground geophysical exploration equipment (such as induced polarization sounding and audio-frequency magnetotelluric methods) in the concentration center to detect the spatial distribution, occurrence and burial depth of low resistivity, high polarizability bodies or ore-controlling structures related to mineralization, so as to achieve a perspective from surface chemical anomalies to underground physical structures.

[0050] A5. On the GIS 3D platform, the surface element anomalies, underground geophysical anomalies and known geological structures are spatially integrated and coupled to establish a "geo-physical-geochemical" integrated model. Based on the anomaly intensity, consistency and geological rationality, several optimal drilling verification targets are selected.

[0051] A6. Design and implement verification drilling for the optimal target location, conduct precise analysis of the obtained core samples to directly verify the accuracy of the comprehensive geophysical and geochemical prediction, and evaluate and provide feedback on the effectiveness of the entire process.

[0052] This invention constructs a highly efficient, economical, and logically closed-loop rapid exploration decision-making system. Its core lies in employing a collaborative logic of "geochemical exploration first, followed by geophysical exploration," and using an X-ray fluorescence detector as the on-site decision-making hub, enabling a rapid transition from large-area scanning to precise drilling target location. This method significantly improves exploration efficiency and prediction reliability through rapid on-site geochemical focusing of the target area and geophysical probe verification of deep structures. On-site screening optimizes cost allocation, and the complete "prediction-verification-feedback" chain continuously optimizes the process. Ultimately, this invention integrates disparate technical means into an organically collaborative exploration "production line," significantly improving the overall efficiency and accuracy of mineral exploration.

[0053] The operation method of the X-ray fluorescence detection device described in step A3 is as follows:

[0054] A31. Move the trolley 1 to the designated position, and use the electric telescopic rod 11 to lower the dust cover 2. The rubber pad 12 will be in contact with the ground and seal the gaps. The bucket 8 of the soil-taking plate 7 will then contact the ground.

[0055] A32. The transmission roller 3 and the conveyor belt 4 are driven to rotate by the motor 6, and the conveyor belt 4 drives the multiple soil sampling plates 7 on its surface to circulate.

[0056] A33. When the soil-removing plate 7 rotates to the lower position, the bucket 8 scoops up the soil and stores it inside. When the soil-removing plate 7 rotates to the upper position, the soil in the bucket 8 falls onto the surface of the conveyor belt 4 under the action of gravity.

[0057] A34. The transmission roller 3 squeezes the air inside the elastic air cushion 14. The compressed air enters the elastic sidewall 13 through the guide hole 15, and then is evenly sprayed out through the spray hole 16, blowing the soil at the edge of the conveyor belt 4 towards the middle of the conveyor belt 4.

[0058] A35. The soil passing over the surface of the conveyor belt 4 is subjected to fluorescence analysis by an X-ray fluorescence analyzer 5 to detect the characteristic X-rays released after the material is excited and to identify the elemental composition contained therein.

[0059] like Figures 2 to 8 As shown, the X-ray fluorescence detection device in step A3 includes a trolley 1; a dust cover 2 is provided on the trolley 1; and a transmission roller 3, a conveyor belt 4, and an X-ray fluorescence analyzer 5 are provided inside the dust cover 2.

[0060] The transmission rollers 3 are provided in a pair and are rotatably connected inside the dust cover 2; one of the transmission rollers 3 is driven by a motor 6.

[0061] The conveyor belt 4 is sleeved on the surface of a pair of drive rollers 3; a set of soil-boring plates 7 are evenly hinged to the outside of the conveyor belt 4; an elastic element is provided between the soil-boring plate 7 and the conveyor belt 4; a bucket 8 is provided at the end of the soil-boring plate 7; a set of shovel teeth 9 are evenly distributed at the bottom of the bucket 8.

[0062] The X-ray fluorescence analyzer 5 is positioned above the conveyor belt 4; the X-ray fluorescence analyzer 5 is used to perform fluorescence analysis on the soil passing over the surface of the conveyor belt 4.

[0063] During operation, the trolley 1 is moved to the designated position, and the transmission roller 3 and the conveyor belt 4 are driven to rotate by the motor 6. The conveyor belt 4 then drives the multiple soil-collecting plates 7 on its surface to circulate. When the soil-collecting plate 7 rotates to the bottom, its bucket 8 contacts the soil, and the soil can be scooped up and stored inside it. When the soil-collecting plate 7 rotates to the top, the soil in the bucket 8 falls onto the surface of the conveyor belt 4 under the action of gravity. The soil passing over the surface of the conveyor belt 4 is subjected to fluorescence analysis by the X-ray fluorescence analyzer 5 to detect the characteristic X-rays released after the substance is excited, so as to quickly and non-destructively identify the elemental composition contained therein.

[0064] During the above process, the elastic element will adaptively adjust the angle of the soil sampling plate 7 according to the hardness and resistance of the soil, ensuring that the bucket 8 can stably cut into the soil and obtain a sufficient amount of sample. By grabbing the soil first and then placing it on the surface of the conveyor belt 4, the original structure of the soil can be destroyed, the detection depth of the soil can be increased, and the internal substances of the soil can be fully exposed so that the X-ray fluorescence analyzer 5 can identify key elements as much as possible.

[0065] In one embodiment of the present invention, an installation frame 10 is provided on the outside of the dust cover 2, and the installation frame 10 is fixedly connected to the trolley 1; an electric telescopic rod 11 is fixedly connected between the installation frame 10 and the dust cover 2; and a rubber pad 12 is fixedly connected to the lower side of the dust cover 2.

[0066] When the equipment is not in operation, there is a gap between the bottom of the dust cover 2 and the ground, and the bucket 8 does not contact the ground, which facilitates the movement of the trolley 1. Before the equipment is started for testing, the dust cover 2 is lowered by the electric telescopic rod 11. The rubber pad 12 at the bottom of the dust cover 12 is in contact with the ground and seals the gap, further preventing dust from escaping outward and polluting the surrounding air during the soil collection process. After the dust cover 2 is lowered, the bucket 8 can contact the ground to ensure that samples can be obtained smoothly in the future.

[0067] In one embodiment of the present invention, elastic guardrails 13 are fixedly connected to both sides of the conveyor belt 4 to prevent soil on the surface of the conveyor belt 4 from falling down through both sides.

[0068] In one embodiment of the present invention, an elastic air cushion 14 is fixedly connected to the inner side of the conveyor belt 4; the elastic air cushion 14 and the elastic sidewall 13 are both designed as hollow structures and are interconnected through guide holes 15; a set of spray holes 16 are evenly distributed on the side of the elastic sidewall 13 near the conveyor belt 4.

[0069] When the elastic air cushion 14 on the inner side of the conveyor belt 4 moves to the drive roller 3, the drive roller 3 will squeeze the elastic air cushion 14, compressing the air inside it. The compressed air enters the hollow structure of the elastic sidewall 13 through the guide hole 15, and then is evenly sprayed out through the nozzle 16. The sprayed airflow can form an air curtain on both sides of the conveyor belt 4. On the one hand, it can blow the soil sample at the edge of the conveyor belt 4 towards the middle of the conveyor belt 4 so that it can be fully captured by the X-ray fluorescence analyzer 5. On the other hand, the airflow can also clean the soil powder attached to the surface of the elastic sidewall 13, preventing long-term accumulation from affecting the protective effect of the sidewall. At the same time, the hollow structure design also reduces the weight of the overall components and reduces the load on the conveyor belt 4 during operation.

[0070] Both the elastic air cushion 14 and the elastic side guard 13 are provided with a set of diaphragms 17; the interiors of the elastic air cushion 14 and the elastic side guard 13 are divided into a set of independent cavities 18 by the diaphragms 17; a set of guide holes 15 are provided and respectively connect the independent cavities 18 of the elastic air cushion 14 and the elastic side guard 13 to each other; the spray holes 16 correspond one-to-one with the independent cavities 18 of the elastic side guard 13.

[0071] By setting multiple diaphragms 17, the interior of the elastic air cushion 14 and the elastic sidewall 13 is evenly divided into multiple independent chambers 18, and the number of independent chambers 18 in the elastic air cushion 14 and the elastic sidewall 13 is the same. The independent chambers 18 of the two are interconnected through guide holes 15, and the spray holes 16 are connected to the independent chambers 18 of the elastic sidewall 13. This independent chamber design allows each chamber of the elastic air cushion 14 to generate and spray compressed air independently and in sequence when it is squeezed by the transmission roller 3, which improves the accuracy of airflow control and avoids the problem of airflow running around or uneven distribution in the traditional integral structure. When a minor damage occurs in one independent chamber 18 during the operation of the conveyor belt 4, the other independent chambers 18 can still work normally, ensuring the continuity and stability of the air curtain. In addition, the setting of diaphragms 17 also enhances the structural strength of the elastic air cushion 14 and the elastic sidewall 13, making them less prone to deformation under long-term repeated squeezing and airflow impact, maintaining a stable working state, and extending the service life of the elastic air cushion 14 and the elastic sidewall 13.

[0072] In one embodiment of the present invention, the elastic element includes a connecting cylinder 19 and a connecting rod 20; the connecting cylinder 19 and the connecting rod 20 are respectively hinged to the conveyor belt 4 and the soil sampling plate 7; a piston 21 is slidably and sealed inside the connecting cylinder 19, and the piston 21 is fixedly connected to the connecting rod 20; a spring 22 is fixedly connected between the piston 21 and the connecting cylinder 19.

[0073] When the conveyor belt 4 drives the soil-taking plate 7 to move, the soil-taking plate 7 contacts the ground and performs soil-taking operations. At this time, the soil-taking plate 7 is subjected to the reaction force of the ground, which will push the piston 21 to slide adaptively in the connecting cylinder 19 through the connecting rod 20. The piston 21 compresses the spring 22 and changes the volume of the two chambers in the connecting cylinder 19.

[0074] In one embodiment of the present invention, a pressure plate 23 is hinged inside the bucket 8; a hollow elastic telescopic block 24 is fixedly connected between the pressure plate 23 and the soil-boring plate 7; the cavity of the connecting cylinder 19 near the soil-boring plate 7 is connected to the elastic telescopic block 24 through a conduit 25.

[0075] The connecting cylinder 19 is connected to the bucket 8 via the conduit 26 in the chamber near the conveyor belt 4.

[0076] As the soil-collecting plate 7 moves from bottom to top, it lifts off the ground when it reaches the left drive roller 3. Spring 22 drives piston 21 to move towards the soil-collecting plate 7, increasing the angle between the soil-collecting plate 7 and the conveyor belt 4. At this time, the volume of the chamber on the side of the connecting cylinder 19 closest to the soil-collecting plate 7 decreases. The internal gas is forced into the elastic telescopic block 24 via conduit 25, causing the elastic telescopic block 24 to expand and push the pressure plate 23 to rotate inside the bucket 8. The pressure plate 23, in conjunction with the inner wall of the bucket 8, compresses the soil entering the bucket 8, increasing the degree of soil fragmentation and further exposing its internal materials. After the soil-collecting plate 7 rotates to the top, the increased angle between it and the conveyor belt 4 improves the efficiency of soil falling from the bucket 8 onto the conveyor belt 4. As the soil-collecting plate 7 moves from top to bottom, the angle between the soil-collecting plate 7 and the ground... The impact force generated by the contact is transmitted to the piston 21 through the connecting rod 20, causing the piston 21 to slide towards the conveyor belt 4 inside the connecting cylinder 19 and compress the spring 22. As a result, the volume of the chamber near the soil-taking plate 7 in the connecting cylinder 19 increases, creating a negative pressure. The gas in the elastic telescopic block 24 flows back to the connecting cylinder 19 through the first conduit 25. The elastic telescopic block 24 contracts and pulls the pressure plate 23 to reset, preparing for the soil-taking operation. At the same time, the volume of the chamber near the conveyor belt 4 in the connecting cylinder 19 decreases. This chamber injects gas into the inside of the bucket 8 through the second conduit 26, realizing that the bucket 8 is sprayed from the inside out, thereby removing the soil remaining in the inside of the bucket 8 during the previous soil-taking process, so as to fully refresh the sample and prevent the new sample from being contaminated or interfered with. This structural design realizes the linkage control of soil taking, soil pressing, dropping, and clearing actions without the need for an additional power source, simplifying the structure of the overall device.

Samples were collected using aquatic sediment measurement techniques and sent to the laboratory for multi-element analysis. Through statistical analysis and mapping, a comprehensive geochemical anomaly zone dominated by gold was delineated at the regional scale. A3. Set up a dense soil monitoring network in the anomaly area, use the X-ray fluorescence detection device to perform multi-element detection, obtain the content data of key elements and generate on-site maps, and focus the areal anomalies to several specific surface element concentration centers. A4. Deploy ground geophysical exploration equipment in the concentration center to detect the spatial distribution, occurrence and burial depth of low resistivity, high polarizability bodies or ore-controlling structures related to mineralization, so as to achieve a perspective from surface chemical anomalies to underground physical structures. A5. On the GIS 3D platform, the surface element anomalies, underground geophysical anomalies and known geological structures are spatially integrated and coupled to establish a "geo-physical-geochemical" integrated model. Based on the anomaly intensity, consistency and geological rationality, several optimal drilling verification targets are selected. A6. Design and implement verification drilling for the optimal target location, conduct precise analysis of the obtained core samples to directly verify the accuracy of the comprehensive geophysical and geochemical prediction, and evaluate and provide feedback on the effectiveness of the entire process.

3. The rapid gold deposit delineation method based on geophysical and geochemical data analysis according to claim 2, characterized in that: The operation method of the X-ray fluorescence detection device mentioned in step A3 is as follows: A31. Move the cart (1) to the designated position, and use the electric telescopic rod (11) to drive the dust cover (2) to descend. The rubber pad (12) will be in contact with the ground and seal the gap. The bucket (8) of the soil-taking board (7) will contact the ground. A32. The transmission roller (3) and the conveyor belt (4) are driven to rotate by the motor (6), and the conveyor belt (4) drives the multiple soil sampling plates (7) on its surface to circulate. A33. When the soil-taking plate (7) rotates to the bottom, the bucket (8) scoops up the soil and stores it inside. When the soil-taking plate (7) rotates to the top, the soil in the bucket (8) falls to the surface of the conveyor belt (4) under the action of gravity. A34. The transmission roller (3) squeezes the air inside the elastic air cushion (14). The compressed air enters the elastic sidewall (13) through the guide hole (15) and is then sprayed out evenly through the spray hole (16) to blow the soil at the edge of the conveyor belt (4) towards the middle of the conveyor belt (4). A35. The soil passing through the surface of the conveyor belt (4) is subjected to fluorescence analysis by an X-ray fluorescence analyzer (5) to detect the characteristic X-rays released after the material is excited and to identify the elemental composition contained therein.
