综放工作面邻近抽放技术的试验研究

Experimental Technology Research on Draining gas of Fully-mechanized Top Coal Caving Face from Adjacent Working Face

通过对综放工作面采场及瓦斯运移的理论研究,提出了利用综放工作面上一个区段已有的巷道,向正在开采的综放工作面顶板施工瓦斯抽放钻孔,抽采采空区瓦斯富集区瓦斯的方法,并进行了现场试验,为综放工作面解决瓦斯超限问题提供了一种新途径。

Based on the theory for fully-mechanized top-coal caving mining and gas migration and the use of a roadway for a fully-mechanized top-coal caving mining section ,the paper proposes a way to drill holes on its roof to drainage enrichment gas in the gob area. Field tests have been clone and the paper provides .a new way to solve the problem of exceeding gas at the fully-mechanized top-coal mining face.
