摘    要:为研究煤体微差爆破致裂提高煤体瓦斯抽放效率,本文采用模拟试验方法以导爆管长度精确控制微差时间,完成了单孔和三孔试件相似模拟爆破试验.单孔爆破试验结果表明:复合型切缝药包水介质耦合装药是最佳装药结构;不同微差间隔三孔爆破试验结果表明:合理微差间隔爆破可以形成确定方向裂缝并在其他方向形成一定的微裂纹.

关 键 词:毫秒爆破  水耦合  爆破成缝

Abstract:To improve mine gas drainage rate by blasting, the simulation blasting tests of one shot hole and three shot holes have been finished. In the test, the initiation can be accurately controlled by the Nonel. One shot hole test results show that water coupling charge is the best charge. Three shot holes test results show that the blasting effect of millisecond blast is superior to instantaneous blasting, and millisecond blast can make not only main cracking but also lots of micro - cracking.
Keywords:millisecond blast  water coupling  blasting cracking
