【摘要】：针对东露天矿开采过程中,爆破钻孔下方存在大范围高温火区,使得钻孔无法装药的现状,分析了高温火区产生的原因,采用温度场反演方法指出最佳灭火介质灌注点,选择了适宜的灭火降温技术,成功将高温火区温度降低到60℃以下,为露天煤矿高温火区的治理提供了参考。
[Abstract]:In view of the fact that there is a large area of high temperature fire area beneath the blasting borehole in the course of mining in East Open-pit mine, the causes of the high temperature fire zone are analyzed, and the optimum fire extinguishing medium pouring point is pointed out by using the inversion method of temperature field. The suitable fire-extinguishing and cooling technology has been selected to successfully reduce the temperature of high-temperature fire zone to below 60 鈩，
