摘　　要：垂直平行密集束状孔落矿有底柱崩落法是一种新的采矿方法.通过爆破模型试验,测试爆破应力、观察分析爆破效果,探求最佳布孔形式,选择最优爆破孔网参数.试验结果表明:用平行束状孔取代扇形孔落矿,改善了爆破效果,简化了采场结构,减少了采切工程量.In the vertical-Parallel concentrated bunch-holes caving, the floor pillar caving is a new mining method. Optimum hole pattern and optimum detonation parameters are obtained by blasting model demonstration, blasting stress testing and blasting effect observation in the blasting operation. The result shows that the demolishing effect is improved, the construction of mind field is simplified and the quantity of ergineering working is reduced.
