摘要:
温度一直是制约煤矿高温火区爆破施工的重要因素，为了在相对高温区域进行爆破作业，采用PVC管注水装药的爆破方法达到预期的爆破施工进度及效果。PVC管注水爆破方法改变原来直接炮孔装药中孔壁与炸药直接接触时热量的传导路线，用PVC管和水将炸药与炮孔隔开,增加隔热层；同时，在PVC管中注水起到了降温作用，延缓了炸药的升温速度，提高了爆破施工作业的安全性及进度。
Abstract:
Temperature has been an important factor to restrict the blasting construction of high temperature fire area in the coal mine. In order to conduct blasting operations at the relatively high temperature range, a new blasting method using PVC tubes filled up with water was designed to meet with the expected progress and outcome. The current application will bring some changes to the heat transmission as a result of direct contact between the hole wall and the explosive in blasting hole charging method. The separation of explosive and blasting hole by waterfilled PVC tubes will create an insulation layer, and the inside water could lower the temperature and thus slow down the heating up of explosive. The new application has improved the safety of blasting construction operation and speeded up the whole process.
