摘要
随着我国煤矿综采技术的推广应用,掘、抽、采比例呈失衡态势,瓦斯抽放技术发展相对落后,以往瓦斯抽采工艺远不能达到要求。为保证煤矿接续生产,各矿陆续引进定向钻机及随钻测量系统工艺,对未形成工作面实行区域预抽。改善目前矿上瓦斯抽放系统的不足,本文主要阐述了柳林煤田的各矿定向施工目的及施工效果。
along with the our country coal mine fully mechanized technology popularization and application, driving, pumping, adopt pro- portional unbalance situation, gas drainage technology development is relatively backward, the gas drainage technology far can not meet require- ments. In order to ensure continuous production of coal mine, all mine introduces directional drilling and MWD system process, do not form a working surface of regional drainage. To improve the present mine gas drainage system is inadequate, this article mainly expounds the Liulin coal mine directional construction purpose and construction.
