摘要
长距离定向钻孔对高瓦斯或突出煤层进行"采前预抽",既能有效解决高瓦斯或突出矿井的瓦斯涌出量大及突出危害、确保安全生产;还能减少环境污染,使瓦斯变废为宝。文以千米定向钻机在高瓦斯或突出矿井进行区域性瓦斯防治为背景,介绍了千米定向钻进新技术,分析了长距离定向钻孔中常遇的问题,提出了切实有效的解决方案,能为今后高瓦斯或突出煤层的瓦斯治理提供技术借鉴。
Gas drainage before exploitation among high-gas or outburst seams with long-distance directional drilling can not only solve the problems like high gas, huge gas emission, outburst and ensure the safety production, but also decrease the environment contamination and turn gas into valuable resources. The paper introduces the kilometer orientated drilling technology, analyzes common problems, and provides effective solutions, which can be useful for the gas control in future.
