兖州矿业(集团)公司东滩煤矿根据矿井特点采取降温措施,有效降低了深部开采综放面温度。该矿煤层埋藏较深,目前开采的-660 m水平岩石地温为29～33℃。地温对工作面气温影响较大且始终存在,目前尚没有可靠的降低围岩地温措施,因此只能从第2大热源电气设备散热入手。通过改进工作面电气设备的布置方式,使顺槽电气设备散热不
Yanzhou Mining (Group) Company Dongtan Coal Mine cooling measures taken according to characteristics of coal mines, effectively reducing the temperature of fully mechanized caving mining face. The coal seam of this mine is deeply buried, and the present-day rock-ground temperature of -660 m is 29-33 ℃. Ground temperature on the face of a greater impact on the temperature and there is always there is no reliable way to reduce the surrounding rock temperature measures, it can only start from the second largest heat source electrical equipment cooling. By improving the arrangement of the electrical equipment on the working surface, the cooling of the electrical equipment in the trough is not
