Hidden structural detection practice of coal mine re-mining working face

Hidden structure in coal mine working face is an important hidden danger affecting safety production, and it is also a difficult technical problem to identify, Mine borehole logging analyzer is a comprehensive borehole logging device for underground drilling, which can quickly complete the work of video, natural gamma ray, trajectory data acquisition in underground coal mine at one time, Ground processing software can process data efficiently, and automatically derive the results of borehole trajectory plane map, borehole trajectory profile map and video core map, etc. By using underground drilling and mine borehole logging technology, the occurrence of coal seams and faults in No. 42224 mining face of Chaijiagou Coal Mine determined by trench wave seismic exploration was analyzed, the concealed structure of the working face was basically identified, and the high efficiency and practicability of the technology in detecting concealed structure were verified, which provides a strong technical support for mine safety production.
