摘要: 对切顶卸压自动成巷无煤柱开采切缝爆破进行试验研究。以亿欣煤业XV1306 工作面为对象,结合亿欣煤业
XV1306 工作面情况,设计了以3 连孔起爆、间隔1 孔的起爆方式为主的爆破试验方案。结果显示,该工作面切顶卸压
自动成巷无煤柱开采切缝爆破施工按500 mm 间距试验最佳结果的爆破参数进行,采用多孔连爆不留间隔孔的方式。

Abstract: The experimental study on the slotted blasting in non-pillar mining for roof cutting and pressure relief automatic
roadway formation was carried out. Taking the XV1306 working face of Yixin Coal Industry Co., Ltd. as the object, combined with
the situation of XV1306 working face of Yixin Coal Industry Co., Ltd., this paper designed a blasting test scheme based on the
initiation mode of three consecutive holes with one hole interval. The results showed that the slotted blasting construction in nonpillar
mining for roof cutting and pressure relief automatic roadway formation in the working face was carried out according to the
blasting parameters of the best results of the 500 mm spacing test, and the method of multi-hole continuous blasting without
interval holes was adopted.
