错层位巷道布置在煤与瓦斯共采上的应用构想

The application idea of using stagger arrangement to achieve simultaneous extraction of coal and gas

随着煤矿开采深度和强度不断增加,瓦斯灾害的发生概率也随之增大,煤与瓦斯共采技术逐渐得到重视。本文致力于为提高煤矿瓦斯抽采率,实现高瓦斯矿井安全、高效生产找到更多可能的有效方法。通过对错层位巷道布置开采首采工作面之后其上覆岩层运动特点进行总结分析,试着从改革巷道布置方面着手,将错层位巷道布置与现有煤与瓦斯共采技术结合,从而提出了错层位巷道布置在煤与卸压瓦斯共采上的应用构想。文中做出了相应的预测,认为采用这种方法,比用传统方法抽采瓦斯在安全、经济方面更具优势,需要通过具体工程实践进行验证。

With the depth and intensity of coal mining increased ,the probability of the occurrence of gas disaster also increased ,more attention has been paid to the simultaneous extraction of coal and gas .This paper is dedicated to find more possible effective methods which can improve coal mine gas extraction rate and realize the safety and efficient production of high gas coal mine .From the aspect of reforming roadway layout and contacting the movement characteristics of the overburden when use stagger mine roadway arrangement after mining the first face ,and combining stagger roadway arrangement with existing coal and gas extraction technologies ,the application idea of using stagger arrangement mining seam to achieve simultaneous extraction of coal and gas was put forward .This paper made a corresponding predicted that this method has advantages in security ang economy compared with the traditional methods .advantages need to be verified by specific engineering practice .And this application idea need to be verified by specific engineering practice .
