摘要
对深孔预裂爆破技术在赵固一矿的应用效果进行了考察,验证了该技术在薄基岩下开采中降低了初次来压强度,避免了工作面大面积受压,保证了工作面的设备不受损坏和工人的人身安全,提高了工作效率。
This paper inspected the application effect of the deep-hole pre-splitting blasting technology in Zhaogu No.1 Coal Mine,and verified that the technology reduced the initial pressure strength in the mining under the thin bedrock,avoided the large area pressure of the working face,guaranteed the equipment of the working face from damage and personal safety,and improved the working efficiency.
