摘 要:为了解决无保护层的煤层区域瓦斯治理的难点,分析了朱仙庄矿煤层及瓦斯赋存状况,提出了在不具备开采保护层的区域内,采用底板穿层钻孔区域防突措施,对掘进巷道进行打钻预抽。在详细介绍底板穿层钻孔的布置、抽采和计量方式的同时,通过理论计算和实际掘进作业两个方面,共同验证了底板穿层钻孔条带预抽区域措施可行性和可靠性,进而为穿层钻孔预抽区域措施在矿区的推广应用提供了范例。In order to solve the problem of gas control in the region of coal seams without protective seam,on the basis of analysis of coal seams and gas occurrence in Zhuxianzhuang Coal Mine,a method of gas control in region without protective seam was proposed,in which by boreholes drilled through floor of coal seam gas is pre-drained from roadways in excavation.Arrangement of boreholes drilled through floor,the ways of gas drainage and measurement were detailed.Theoretical calculation and engineering practice proved feasibility and reliability of the method.The case study provides an example for the method promotion in the mining area.
