Description

Technical fields:

[0001] This invention relates to a precision mining technology for karst-type gold mines, belonging to the field of well mining operations. Background technology:

[0002] Cave-type gold deposits are an important type of gold ore body, characterized by their considerable size and often relatively high ore grade. 。 It is a ore-bearing structure that contains gold-bearing hydrothermal fluids. It is a gold ore body enriched in a natural cave formed by the geological action of groundwater, which caused the collapse, deposition, leaching, and secondary enrichment of pre-formed vein-like gold polymetallic ore bodies and marble karst.

[0003] The ore grade is affected by the enrichment degree and enrichment variation of gold in the karst-type gold ore body, which leads to the need to take samples and conduct tests before mining each layer. After obtaining the test results, subsequent mining processes such as hole layout, rock drilling, and blasting are carried out. Before hole layout, the stope needs to be sampled and hole layout is carried out according to the test results, which makes the mining process complicated and the cycle long. At the same time, the high-grade ore is lost and diluted due to the co-mining of high- and low-grade ore. Summary of the Invention:

[0004] The purpose of this invention is to provide a precision mining process for karst-type gold mines that can quickly achieve precise mining of karst-type mines by progressively decreasing the grade of ore from high-grade to low-grade, thereby improving mining efficiency and the quality of extracted ore.

[0005] This invention is implemented by the following technical solution: a precision mining process for cave-type gold mines, which includes the following steps:

[0006] Step 1: Determine the sampling points in the mining area;

[0007] Step 2: Take pictures of the sampling points determined in Step 1 to obtain the sampling point image information;

[0008] Step 3: Sample the sampling points taken in Step 2 to obtain the sampled data;

[0009] Step 4: Test the sample obtained in Step 3 to obtain the gold content data of the sample;

[0010] Step 5: Combine the gold content data of the sample obtained in Step 4 with the image information of the sampling points in Step 2 to obtain the gold content image information;

[0011] Step 6: Take photos of the mining area to obtain image information of the mining area;

[0012] Step 7: Compare the mining area image information obtained in Step 6 with the gold content image information obtained in Step 5 to obtain the gold content distribution map of the mining area.

[0013] Step 8: According to the gold content distribution map obtained in Step 7, the ore body in the mining area is precisely mined in order of gold content from high to low.

[0014] Preferably, in step 1, there are 15 or more sampling points.

[0015] Preferably, the settings of the camera device are the same in steps 2 and 6.

[0016] The advantages of this invention are: compared with the prior art, it eliminates the sampling and testing process for each layer, and can quickly realize precise mining of karst-type mines from high-grade ore to low-grade ore in a step-by-step manner, thereby improving mining efficiency and the quality of mined ore, and also avoiding the loss and dilution of high-grade ore caused by the mixed mining of high-grade and low-grade ore. Detailed implementation method:

[0017] Example: Precision mining technology for cave-type gold mines, comprising the following steps:

[0018] Step 1: Determine sampling points in the mining area, with at least 15 sampling points;

[0019] Step 2: Take pictures of the sampling points determined in Step 1 to obtain the sampling point image information;

[0020] Step 3: Sample the sampling points taken in Step 2 to obtain the sampled data;

[0021] Step 4: Test the sample obtained in Step 3 to obtain the gold content data of the sample;

[0022] Step 5: Combine the gold content data of the sample obtained in Step 4 with the image information of the sampling points in Step 2 to obtain the gold content image information;

[0023] Step 6: Take photos of the mining area to obtain image information of the mining area;

[0024] Step 7: Compare the mining area image information obtained in Step 6 with the gold content image information obtained in Step 5 to obtain the gold content distribution map of the mining area.

[0025] Step 8: According to the gold content distribution map of the mining area obtained in Step 7, the ore body of the mining area is precisely mined in order of gold content from high to low.

[0026] In steps 2 and 6, the settings for the camera are the same.
