| 摘 要： | 控制预裂爆破技术作为区域防突措施的补充,能快速有效地消除煤巷掘进工作面的局部突出危险性,为了合理布置控制预裂爆破技术中的控制孔和爆破孔,通过理论计算和现场测试两种方法,得出控制预裂爆破单孔的有效影响半径为2.5 m,以此为设计依据对控制预裂爆破钻孔进行了科学合理的布置,并对布孔方式进行了效果检验。结果表明,这种方法能够快速有效地消除掘进工作面前方的突出危险性,提高煤巷掘进的速度,缓解矿井采掘接替紧张的局面。

| Abstract: | As a supplement to regional outburst prevention measures,the controlled pre-splitting blasting technology can quickly and effectively eliminate the local outburst hazard at the coal driving face.In order to reasonably arrange the control hole and the blasting hole in the controlled pre-splitting blasting technology,both the theoretical calculations method and field testing method are applied in this paper,and the effective influence radius of the single hole of the controlled pre-splitting blasting is 2.5m.... |
