摘要
在低透气性突出煤层,瓦斯抽采难度大,效率低,不能有效的达到抽掘采平衡,本文从影响抽采效率的因素出发,寻找提高效率的实践方法,通过现场实践和数据论证,阐明了提高抽放效率的可行性技术。
Prominent in low-permeability coal seam gas extraction is difficult, inefficient and can not effectively achieve the extraction of the mining excavation balance,this article from the impact of the efficiency of extraction of factors,the search for methods to improve efficiency of practice,practice and data through on-site demonstration,to clarify to improve the efficiency of the feasibility of drainage technology.
