摘要
为了解决石炭系特厚煤层综放工作面在生产特殊时期需过大量岩石区域的问题,提出了用深孔爆破的方法在巷道预裂岩石区域来减小回采时截割岩石的阻力,实施该方法后,工作面过岩石区域时岩石已经松动破碎,可较快通过岩石区域,现场取得了较好的效果。
In order to solve the problem that a large number of rock areas are needed in the fully mechanized top coal caving face in the extra-thick carboniferous coal seam during the special production period,a method of deep-hole blasting in the pre-split rock area of roadway is proposed to reduce the resistance of cutting rock during mining,after carrying out this method,when the working face passes through the rock area,the rock has been loosened and broken,and can pass through the rock area quickly.
