【摘要】：为了提高煤矿火区高温爆破的安全性,采用远程控制装置进行装药施工。结果表明:远程控制装置可在远程控制一次性完成下放导爆索、装药、堵塞工作(危险时段),装置中的钢管以及容器底部少量的堵塞物能防止雷管爆炸产生的能量与冲击波引爆容器内部的炸药,另外,开关网路可使所有炮孔同时完成下放导爆索、装药、堵塞的工作,使整个炮区中在最短时间内完成装填工作并引爆炸药。远程控制装药施工方法使施工人员远离高温火区,在实际应用中操作简便,克服了传统高温爆破工艺限制炮孔孔数的不足,能够对高温火区进行大规模爆破,从而提高矿山剥离挖运效率,并提高高温爆破的安全性。
[Abstract]:In order to improve the safety of high temperature blasting in coal mine fire area, the remote control device is used for charge construction. The result shows that the remote control device can complete the down-detonation cable and charge at one time in remote control. Blockage operation (danger period, steel tubes in the device and a small amount of blockage at the bottom of the vessel can prevent detonators from exploding energy and shock waves to detonate explosives inside the vessel, in addition. The switch network enables all the holes to simultaneously complete the work of dropping the detonator, charging, and plugging. The loading work and detonation of explosives are completed in the shortest time in the whole gun area. The remote control charge construction method makes the construction personnel far away from the high temperature fire area and is easy to operate in practical application. It overcomes the limitation of the number of holes in the traditional high temperature blasting technology, and can carry out large-scale blasting in the high temperature fire area, thus improving the efficiency of stripping and transporting in the mine and improving the safety of the high temperature blasting.
