Paper Title:
Study on Rational Deployment of Dewatering Depressurization Project of the Cambrian Limestone Geothermal Water
  Abstract

Based on the analysis of geological structure and characteristics of the Cambrian limestone’s aquifer in the eighth mine of Pingdingshan Coal Mining Cooperation, defining rich aquifer regions of the Cambrian limestone , influencing radius in mining aquifer, thickness of water isolated stratum and geothermal gradient between the Group F seam’s base and the Cambrian limestone’s roof by TEM and DC electrical methods,7 dewatering depressurization holes at a depth of 150m are designed to discharge the Cambrian limestone’s geothermal water in the West Roadway’s floor of Group F seam. 7 discharge water holes’ water inflow is 300 m3/h , and the Cambrian limestone’s drawdown is 17.2 m in the West Roadway in 277 days. The geothermal water temperature is 50°C and the water can be raised to the surface for comprehensive utilization, in order to reduce the high pressure geothermal water hazards and avoid the waste of geothermal water, which is great significant for safety production in coal mines , energy saving and emission reduction.
