摘要
目前国家政策推行在冲击地压矿井中应用采掘机械智能化背景下,更换原掘进工艺势在必行,通过炮掘工艺与综掘工艺优缺点对比,综掘工艺在该矿三软、大倾角、冲击地压煤层中推广应用后,提高了掘进工作面安全系数和工作效率。
At present, the national policy promotes the application of the mining machinery intelligence in the impact ground pressure mine, it is imperative to change the original driving technology, by comparing the advantages and disadvantages of the blasting driving technology and the comprehensive driving technology, the application of fully mechanized heading technology in the soft coal seam with large dip angle and rock burst has improved the factor of safety and working efficiency of heading face.
