Comprehensive Exploration of Water Damage in 200 Working Face of Shuanglong Coal Mine
The water hazard in 200 working face of Shuanglong Coal Mine was unknown.In order to determine the water hazard in the area,the method of geophysical exploration combined with drilling was applied for comprehensive study.High-density electrical exploration was used to determine 9 low-resistivity anomaly areas,with a total of 4.75×104 m2.The water quantity was verified by drilling,and the regional hydrogeological type was determined to be simple type dominated by fissure water filling.Through comprehensive exploration,it can be seen that the water damage risk and water quantity in the 200 working face area were small.
