中梁山煤矿是一个具有煤与瓦斯突出的超级瓦斯矿井,在生产建设中,揭开“突出”煤层的工作量相当大.建矿以来,全矿共发生47次煤与瓦斯突出,其中揭开“突出”煤层发生了16次.重大的瓦斯事故都发生在揭煤过程中.这是我矿进行生产准备在安全上的一个重大隐患.而石门突出发生的原因中,因放炮引起的突出就占87%.因此,如何搞好石门揭煤放炮工作,对促进我矿煤炭生产的迅速发展具有十分重要的意义.过去我们放震动炮采用矿井动力线路远距离放炮办法,也可以达到目的.但要调改线路设备的闭锁装置、敷设临时电缆和安装
In Liangliangshan Mine, a super-gas mine with coal and gas outburst, the workload of uncovering “prominent” coal seams is quite large in production and construction. Since the construction of the mine, 47 coal and gas outbursts have occurred in the mine, “Outburst” seam occurred 16 times.Major gas accidents occurred in the uncovering process, which is my mine production safety in preparation for a major hidden danger.But Shimen salient reasons, due to blasting caused by the outstanding Accounting for 87% .Therefore, how to do a good job in Shimen exposing blasting coal, to promote the rapid development of coal mining in our mine has a very important significance.In the past we put the shock cannon mine using power line long-range blasting method can also be achieved. To change the line equipment, locking device, the laying of temporary cables and installation
