二道沟矿深井开采热环境研究

二道沟矿井下作业面最高温度已超过30℃,深井高温热害已成为制约矿山安全高效开采和深部资源综合开发利用的重大技术难题之一。深井开采热环境研究是深井开采热害治理的基础,通过井下微气候参数测试、作业人员工作环境主观感受调查、高温采场热力分析及矿井通风系统热模拟等研究手段与方法,对该矿井下热环境及其变化规律进行了深入的分析,为矿山下一步的深井开采热害综合治理研究提供了技术保障。

Study on thermal environment of deep mining in Erdaogou mine

The underground temperature at the working face in Erdaogou gold mine is as high as 30 ℃. As a re- suit, the deep heat harm has become one of the major technical problems that restrict saree and efficient mining as well as deep resources development and utilization of the mine. The thermal environment research of deep mining is the foundation of heat influence control. Through underground microclimate parameter tests, investigations of the operat- ing workers＇ subjective feelings in the working environment, thermal analysis of the stope at hot environment and the thermal simulation of the mine ventilation system, the deep mining thermal environment and its change are analyzed in detail, which may provide technical supports for comprehensive control of heat influence in deep mines.
