辰通煤业综放工作面多位一体瓦斯治理技术

Multi-in-one Gas Control Technology in Fully Mechanized Top Coal Caving Working Face of Chentong Coal Industry

为了解决辰通煤业回采工作面瓦斯涌出量大、上隅角瓦斯浓度高的问题,结合矿井瓦斯涌出特点和二盘区地质情况,通过实施本煤层预抽、上隅角抽采和邻近层瓦斯抽采相结合的多位一体瓦斯抽采方法,分别对回采工作面煤层瓦斯、采空区瓦斯和邻近层瓦斯进行抽采,从而控制回采工作面瓦斯涌出量,实现了回采工作面安全开采。

In order to solve the problem of large gas emission and high gas concentration in the upper corner of the mining working face of Chentong Coal Industry,combined with the characteristics of mine gas emission and the geological conditions of the NO.2 plate area,through the implementation of the multi-in-one gas drainage method of the pre-drainage of this coal seam,the upper corner drainage and the adjacent layer gas drainage,the coal seam gas,goaf gas and adjacent layer gas are extracted respectively.As a result,the amount of gas emission from the mining face is controlled and the safe mining of the mining face is realized.
