在煤矿掘进过程中,中深孔爆破是比较常用的爆破技术,对采煤作业有着重要的作用。文章介绍了煤矿掘进中深孔爆破的炮眼设置、掏槽方式、起爆方式、安全管理等问题,并分析了拒爆原因,提出了相应的处理措施。希望能够引起人们对这一技术的就能一步重视,能够对煤矿掘进中深孔爆破的实际工作提供借鉴与参考。
In the process of coal mining, medium-deep borehole blasting is a more commonly used blasting technique and plays an important role in coal mining operations. The article introduced the blasthole setting, undercutting mode, detonating mode and safety management of deep hole blasting in coalmine tunneling. The reason of rejecting blasting was analyzed and the corresponding treatment measures were put forward. It is hoped that people can pay more attention to this technology and provide reference for the practical work of deep-hole blasting in coal tunneling.
