带有控制孔的深孔松动爆破技术在过断层中的应用研究

Application of Deep-hole Blasting Technology with Control Holes in Removing Hard Fault

采煤机直接破碎坚硬岩石断层的效率较低。通过设计带有控制孔的深孔松动爆破技术预先使岩石破裂,可以提高采煤机破碎岩石的效率。实践表明,带有控制孔的深孔松动爆破为综采工作面过坚硬断层提供了一条解决问题的途径。

The efficiency of making the rock broken by the shear directly is low. It can be improved through using deep-hole loose blasting technology with control holes to rupture the rock firstly. Practice has proved that deep-hole loose blasting with control holes provides a way for the fully-mechanized mining face to pass the hard fault of rock smoothly.
