工作面预留煤爆破法直接过断层技术

Technology of Passing Through Faults Directly Using Explosion Method with Pre-retaining Coal at Face

根据工作面的实际情况,采用预留煤底爆破法直接过断层,并采用聚氨酯帮锚技术,减少了储量损失,减少了搬家次数,提高了单产和经济效益。

According to the actual situations of face, the bottom explosion method with pre - retaining coal is applied in passing through faults directly. The side anchor technology with polyurethane is also applied. The reserve loss is reduced. The number of moving is reduced. The yield and economic benefits are raised.
