摘要
结合双鸭山矿区集贤煤矿煤层瓦斯地质特征,通过超长钻孔施工工艺参数、爆破装药结构设计,提出超长钻孔爆破煤层瓦斯增透技术,并对瓦斯抽采工艺进行研究,最终实现集贤煤矿煤层瓦斯安全抽采。
Combined with the geological characteristics of Jixian Coal seam gas in Shuangyashan mining area,the super long drilling technology parameter,blasting charge structure design,the gas drilling and blasting long AR technology,and the gas of mining technology,the eventual realization of Jixian Coal seam gas drainage of coal mine safety.
