摘　　要：天井是井下采矿不可缺少的一项重要工程,传统的天井施工方法存在劳动强度大、效率低、安全性差的缺点。针对此问题,本研究提出了综合成井法的深孔爆破方式,通过爆破机理分析,应用现场爆破成井实例进行验证。研究结果表明,该法具有安全性高、成井效率高及成本低的特点。在凿岩爆破方面,对施工过程中遇到的关键问题,提出了相关的控制措施。通过现场优化爆破分段高度试验,得出了在此条件下的最优分段高度为4.3 m,为该方法在同类矿山推广过程提供了借鉴。The patio is an indispensable and important project in underground mining.The traditional patio construction method has the disadvantages of high labor intensity,low efficiency and poor safety.In order to solve this problem,this study puts forward the deep hole blasting method of comprehensive well completion method,and verifies it by analyzing the blasting mechanism and applying the field blasting well completion example.The research results show that this method has the characteristics of high safety,high well completion efficiency and low cost.In the aspect of drilling and blasting,the relevant control measures are put forward for the key problems encountered in the construction process.Through the field experiment of optimizing blasting sublevel height,the optimal sublevel height under this condition is 4.3 m,which provides reference for the popularization of this method in similar mines.
