摘　　要：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。築ased on the coal layer unloading method by deep hole blasting, The authors usedaccumulating equipment to imporve explosion energy, helping crevice to expend, connecting with other crevice, increasing coal permeation rate. The authors built simulationsoftware with the help of the Visual C++ language, draws the curve about the crevicelength, damage, permeation rate. At last, the authors conclude that directed blasting isbetter than traditional basting.
