Geothermal Disaster Comprehensive Prevention and Control Measures in Construction Mine

Abstract：According to less study on the geothermal disaster control technology of the construction mine and the geothermal control com- plicated status, based on the mine geothermal disaster features of high environment temperature of the mine roadway heading face, high loading of temperature reducing; high cooling lost of the ventilation supply along the routing, thermal and moisture change insufficient be- tween the low moisture air and the roadway heading face and the low utilization rate of the temperature cooling equipment in the construc- tion mine, a comprehensive control measures combined with the non-mechanical refrigeration and mechanical refrigeration were designed for the temperature cooling of the construction mine. The non-mechanical refrigeration method would include a ventilation volume in- creased, a rational ventilation mode selected, double roadways heading, ventilation with double insolated air ducts, thermal sources con- trol, management enhanced and others. When the non-mechanical cooling method could not meet the requirements of the temperature cooling, the mechanical temperature cooling method would be applied. An analysis was conducted on Zhaolou construction mine as exam- ple. The analysis showed that the operation effect of the mechanical cooling system was good and the temperature of the roadway heading face in the underground mine could meet the requirements of Mine Safety Regulations.
