摘　　要：论述立井深孔掏槽爆破理论与技术发展现状，对新型的立井深孔分段掏槽爆破进行了数值模拟及现场应用研究。结果表明，采用这种掏槽爆破方式，可使立井深孔爆破的炮眼利用率达到85％～90％，取得明显的经济效益和社会效益。The progression in theory and technology of longhole cat blasting is expounded and the numerical simulation and site tests of longhole staged cut blasting method for shaft excavation are discussed in this paper. The longhole utilization factors of 85%-90% have been obtained by use of the new method of cut blasting with obvious economic and social benefits.
