A full exploration and understanding of the hydrogeological environment around the mine can avoid the mining accidents caused by the unfamiliarity with the hydrogeological environment in the process of coal mining. Mine hydrogeology exploration has always been a difficult technical problem in mine exploration, with strong hydrogeology concealment and regional characteristics. It is difficult to guarantee the accuracy of exploration through a geophysical exploration technology. Therefore, it is necessary to strengthen the investigation of mine hydrogeological environment by combining different geophysical exploration techniques to make up for the shortcomings between different geophysical exploration techniques, so that the survey results can be mutually verified, thus improving the accuracy of the survey results and improving the safety of mine excavation.展开更多

The water prevention and control effect is fully guaranteed and plays a key role in the safety in production of coal mines. As one of the main energy sources, coal has a large number of mined-out areas due to long-term mining. Due to the differences in geological conditions, it is necessary to apply the comprehensive geophysical exploration technology scientifically and reasonably to provide technical support for water prevention and control. In this paper, the commonly used geophysical techniques are discussed respectively, and the application of integrated geophysical techniques is studied in order to improve the effect of water prevention and control in coal mines.展开更多
