摘要
经对赵庄矿实施穿层钻孔预抽煤巷条带煤层瓦斯进行治理效果的分析,验证了赵庄矿进行瓦斯治理以掩护顺槽掘进的可行性,并对实施穿层钻孔进行瓦斯抽采过程中的层位选择、钻孔布置、封孔工艺等进行了说明,从而为矿井安全高产高效生产提供技术支持和安全保障。
On the analysis of gas control effect in pre-drainage roadways of belt seams in Zhaozhuang Mine by layer-through borehole, the paper verified the feasibility of covering gateway excavation with gas control. In addition, horizon selection, borehole layout, and sealing process in the process of gas drainage of layer-through borehole are illustrated, which could provide technological support and safety insurance for efficient and safe production.
