1 深孔爆破技术研究的主要内容及方法深孔爆破技术是在工作面一条平巷中采用强力煤电钻和联接式钻杆 ,平行于工作面钻出一个或一组深孔炮眼。将炸药卷用导爆索按照一定的间隔连接后 ,利用钻杆拉入炮眼内 ,装入雷管 ,炮眼两端炮泥封堵 ,发炮器引爆落煤 ,实现一次起爆。研究的主
1 main contents and methods of deep-hole blasting technology Deep-hole blasting technology is the use of powerful coal electric drill and joint drill pipe in a laneway face, drilled one or a group of deep-hole blastholes parallel to the working face. After the explosive coils are connected with the detonating cord according to a certain interval, they are pulled into the blasthole by the drill pipe, the detonator is installed, the blasting mud is blocked at both ends of the blasthole, and the blasting device detonates the coal to achieve a detonation.
