本论文是在深孔卸压爆破基础上，研究采用切缝药包装置，提高爆破能量利用率，使裂纹进一步向纵深扩展，沟通原有裂纹，提高煤层渗透率。并用VisualC＋＋语言开发了爆玻模拟软件，并模拟了不同抗拉强度下的裂隙，损伤因子，渗透率的变化曲线，得出切缝药包爆破要优于普通爆破的结论。
In this paper, based on the deep-hole pressure relief blasting, the research adopts the kerf bag device to improve the utilization rate of blasting energy, make the crack further extend to the depth, communicate the original cracks and improve the permeability of the coal seam. The software of explosive glass explosion was developed by using Visual C ++ language. The curves of crack, damage factor and permeability under different tensile strengths were simulated. The conclusion was drawn that the kits of cracked kits should be better than ordinary blasting.
