Description

Technical Field

[0001] The present invention relates to the field of mining development detection technology, in particular to a mine wall geological acquisition and detection method. Background Art

[0002] Sampling in mining development is a crucial step in ensuring the accuracy of mineral resource exploration and assessment. The sampling process must adhere to certain principles and methods to ensure representative samples, thereby providing reliable data support for subsequent analysis and assessment.

[0003] The sampling method should be determined based on factors such as the size, thickness, structural structure, and mineral grain size of the ore body. For example, when sampling a tungsten ore body, systematic sampling is usually carried out in different areas of the ore body, such as the head and tunnel faces. The collected samples are then processed and tested to determine the boundaries of the ore body and provide a basis for further development of the mine.

[0004] During the sampling process, selective sampling must be avoided, that is, not avoiding the poor in favor of the rich or avoiding the rich in favor of the poor, to ensure the representativeness of the sample. In addition, sampling should be random and uniform, and detailed records should be kept to facilitate subsequent analysis and data management.

[0005] After sampling, samples undergo a series of preparation and analysis procedures. Sample preparation includes crushing, mixing, and fractionation to create test samples that meet testing requirements. In the laboratory, samples are tested using various analytical techniques, such as X-ray diffraction (XRD), infrared spectroscopy (IR), and scanning electron microscopy (SEM), to qualitatively and quantitatively analyze the mineral composition. Summary of the Invention

[0006] The purpose of the present invention is to provide a mine wall geological acquisition and detection method to solve the problem that existing mine sampling is inaccurate and the error between sampling test results and actual results is large.

[0007] In order to solve the above problems, the present invention adopts the following technical means: A mine wall geological acquisition and detection method comprises the following steps: S100. Collect rock samples from multiple mine walls as reference samples; S200. Splitting and mixing multiple reference samples to prepare a mixed sample; S300. Divide the mixed sample into the number of reference samples and select the mixed sample in the middle or at both ends as the test sample; S400. Add water to the test sample to prepare a slurry, and then test the slurry.

[0008] Furthermore, the step S100 includes: S110. Determine the sampling points on the mine wall; S120. Use a hollow borer sampler to take samples according to the locations of the sampling points, and each sample is used as a reference sample.

[0009] Furthermore, in step S110, the sampling points include outer edge sampling points and central sampling points, the outer edge sampling points are arranged in a regular triangle, a regular quadrilateral or a regular pentagon, and the depth of the sampling points is 30-60 cm.

[0010] Furthermore, the step S200 includes: S210. The reference sample collected each time is divided according to the sampling direction in a ratio of 1:2:1, and the sample is crushed after division; S220. Mix the reference samples at the same segmentation position to obtain three groups of mixed samples.

[0011] Furthermore, in step S300, after the test sample is selected, the test sample needs to be screened to screen out particles smaller than 50 mesh for detection.

[0012] Furthermore, in step S400, the amount of water added to the test sample is 20-30% of the weight of the test sample.

[0013] The present invention has the following beneficial effects during the sampling process: It can improve sample representativeness, ensuring that each sample component is equally representative of the whole, thereby avoiding over- or under-representation of certain components, which can lead to biased analytical results. It can also reduce errors and improve sample representativeness, thereby increasing the confidence of statistical analysis. By ensuring equal opportunity for each sample point, the sampling process is transparent and free from subjective factors. It can also optimize sampling efficiency, enabling refined management, accurately predicting grade changes during ore mining, reducing mining dilution rates, and improving resource utilization efficiency. Furthermore, it can avoid contamination and interference, and the sampling device can be cleaned after each sampling to prevent cross-contamination, ensuring sample accuracy and representativeness. Most importantly, it can improve analytical accuracy and better reflect geological characteristics and ore grades, which is of great significance for mineral exploration and evaluation.
