Challenges Faced by Geophysical Detection Technology in Mine Geological Guarantee System

With an analysis on the development status of the geophysical detection technology in the geological guarantee system of the mine high efficient mining, the paper pointed out four major challenges faced by the present geophysical detection technology.The challenges were the high accurate advance investigation of the water disaster in the mining goaf, the detection of the hidden structures in the overlong and over wide coal mining face, detail detection of the hidden structures in the fl oor of the deep seam and the prediction and early warning of the dynamic disasters during the coal mining period.The analysis showed that the challenges could be tak en up with further upgrading the capacity and level of the available geophysical exploration technology to comprehensively solve the geological problems, the research and development of the technology and equipment for the dynamic disaster monitoring and measuring early warning for the mining operation and the continuous innova tions on the idea and mode of the mine geological protection system in order to better play the role of the geophysical exploration technology in the mine high efficient a nd safety mining geological protection system.
