Description

Mining geology reconnaissance probing sampling device

Technical Field

The utility model belongs to the technical field of drilling sampling, and particularly relates to a mining geological investigation drilling sampling device.

Background

The drilling and sampling are used for exploring geological conditions, knowing lithology and geological structures, exploring hydrogeological conditions, exploring bottom surfaces and physical geological phenomena and extracting rock and soil samples and water samples. The mine drilling sampling is to collect a small part of ore or rock from ore bodies or some geologic bodies for analysis, test and identification, so as to achieve the specialization of researching the quality, rock characteristics and performance of the ore. The key issue of sampling is the reliability and representativeness of the sampling. Reliability refers to the degree of accuracy, i.e., the magnitude of technical error, of individual sample collection, processing, and measurement. Representative refers to the degree to which the sampled sample represents the sampled object. Factors influencing the sampling representativeness are the number, distribution and spacing of the samples and the geometric characteristics of the samples, in addition to the varying size of the ore body itself. However, the traditional sampling mode has large labor workload and is unfavorable for large-scale sampling.

The mining geological sampling device with the publication number of CN111537259A comprises a rotating piece, a connecting rod, a sampling tube, a bulldozer and a supporting device; the rotating piece is connected with the sampling tube through a connecting rod, one end of the connecting rod is provided with a threaded part, and the connecting rod is connected with a supporting device; the supporting device comprises a cylinder, a first threaded hole matched with the threaded part is formed in the cylinder, a plurality of connecting blocks are arranged on the circumferential side face of the cylinder, a supporting rod is connected to the connecting blocks in a rotating mode, a plurality of strip-shaped holes are formed in the surface of the sampling tube along the length direction of the sampling tube, a bulldozing piece is connected to the sampling tube, and the bulldozing piece is in sliding connection with the sampling tube through the strip-shaped holes. According to the utility model, the supporting device is connected to the connecting rod, so that the device is stable in sampling, the connecting rod is in threaded connection with the supporting device, time and labor are saved in sampling, the bulldozing piece is connected to the sampling pipe, and the soil in the sampling pipe is conveniently taken out. But the supporting device is three rod bodies, and the stability of the supporting device can be influenced for the environment with poor terrain or soil.

Therefore, the mining geological survey drilling sampling device is used for improving the efficiency of drilling sampling and ensuring the stability of the using process.
