摘要
为了提高煤矿的产能,降低生产成本,吕梁矿工作面回采期间过大断层、无炭柱期间需要放震动炮,程序繁琐且费用巨大,严重影响工作面推进和产量。结合该矿地质构造情况,提出了回采工作面过大断层、无炭柱超前预裂爆破技术,实践取得了成功。
In order to improve coal production and reduce production cost, Lvliang Mine recovery working face crossing large fault and non-coal pillar needs vibration shot, with trivial program and huge cost, which affects working face advancing and production, combined with the mine geological structure, recovery working face crossing large fault and non-coal pillar advanced pre-splitting blasting technology was put forward with success.
