摘要
为解决泉店煤矿14010工作面热害问题,通过分析工作面热量来源,即原岩温度、空气自压缩放热、煤体散热、设备散热等,理论计算工作面最佳风量为22 m^(3)/s,同时采取工作面下行通风、喷雾洒水、机械制冷等措施,工程实践证明工作面温度维持在28℃左右。
In order to solve the heat damage problem of the 14010 working face in Quandian Coal Mine, by analyzing the heat sources of working face, such as original rock temperature, air self-compression heat release, coal body heat dissipation, equipment heat dissipation, etc., the optimum air volume of working face is calculated to be 22 m^(3)/s, at the same time, measures such as downward ventilation, spray water spraying and mechanical refrigeration are adopted. The engineering practice proves that the temperature of the working face is maintained at about 28 ℃.
