摘要
通过测试新元煤矿3号煤层瓦斯基础参数,分别研究了瓦斯压力和瓦斯含量与埋深的关系。采用分源预测法对矿井瓦斯涌出量进行预测,分析了矿井进行瓦斯抽采的必要性和可行性,得出:新元煤矿3号煤层开采期间,建立瓦斯抽采系统对3号煤层及其邻近层和采空区的瓦斯进行抽采是必要的和可行的。
Through the test of basic parameters gas in No.3 coal seam,the author studied the relationship between gas pressure and content.And adopt source prediction method forecasted gas emission,and analyzed the necessity and feasibility of gas extraction.We found that during the mining of Xinyuan Coal Mine,it is necessary and feasible to build gas extraction at adjacent layer and goaf of No.3 coal seam.
