摘要
文章总结了顶煤预爆破现场试验情况介绍了顶煤预爆破效果监测方法,给出了预爆破工艺参数。得出远离煤壁预爆破破碎顶煤试验工艺是可行的。
This paper is summarized an in-situ test of pre-blasting top coal of fully-mechanized top-coal caving mining face. The monitoring method of the effect of pre-blasting top coal is presented. Moreover, the process of the pre-blasting is provided. It is concluded that the approach and process parameters using pre-blasting at far away from mining face to crush top coal is feasible.
