【摘要】：針對東露天礦開采過程中,爆破鉆孔下方存在大范圍高溫火區(qū),使得鉆孔無法裝藥的現(xiàn)狀,分析了高溫火區(qū)產(chǎn)生的原因,采用溫度場反演方法指出最佳滅火介質(zhì)灌注點,選擇了適宜的滅火降溫技術(shù),成功將高溫火區(qū)溫度降低到60℃以下,為露天煤礦高溫火區(qū)的治理提供了參考。
[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，
