Exploration of Coal Mining Face Structure and Water Rich Anomalies
Geological structure and water rich areas are the main factors affecting the safe mining of coal mining faces.If the geological structure and water rich areas are not exposed in a planned manner,it will not only affect the excavation efficiency of coal mines,but also cause safety accidents.Taking 80201 first mining face of the 8#coal seam in Shanxi A Mine as the research object,comprehensive geophysical exploration and drilling techniques were used to detect the mining face structure and rich water area,as well as the use of slot wave seismic detection and radio wave tunnel perspective technology to detect abnormal structural areas.Based on the detection results,the range of the rich water area was determined using audio electric perspective method.Finally,the water outlet area of the detected borehole was drained and grouted for sealing.The mining exposure showed that there were geological structures such as faults in the mining face until it reached the geophysical anomaly area,and there was a small amount of water seepage on the roof when it reached the rich water area,indicating that the detection technology used on site had a good effect.
