Description

Technical Field

[0001] The utility model relates to the technical field of coal mine exploration, in particular to geophysical prospecting, exploration and excavation equipment for coal. Background Art

[0002] Coal mine exploration refers to the process of exploring, evaluating, and developing coal resources to ensure safety, efficiency, and economic benefits. Geological exploration technologies are crucial foundational to coal mine exploration. These technologies, including drilling, well logging, and seismic wave detection, are used to obtain information on underground coal reserves, coal seam inclination, and lithology.

[0003] Exploration equipment is required in coal mine exploration. During the use of existing equipment, coal mines and soil are usually sampled through sampling cylinders to achieve the effect of analyzing coal quality. However, when taking out samples, the sampling cylinders need to be repeatedly disassembled and installed to achieve the sampling effect. The sampling process is relatively cumbersome, which affects the efficiency of coal mine exploration. In addition, coal mine exploration requires the use of dust detectors to monitor coal mine dust, but the dust detectors are inconvenient to clean. Long-term use will cause dust to adhere to the surface of the dust detector, affecting the monitoring effect of the dust detector.

[0004] Therefore, it is necessary to provide a new geophysical prospecting and excavation equipment for coal to solve the above technical problems. Utility Model Content
