西铭矿煤层气资源安全高效开采利用研究

Research on Safe and Efficient Exploitation Coalbed Methane Resources in Ximing Coal Mine

西铭矿属国有大型矿井,同时为高瓦斯矿井,近年来随着瓦斯治理工作的加强,矿井瓦斯抽采量逐步增大,因此,煤层气资源高效开采利用成为矿井低碳发展的重要前提。本文通过分析高抽巷投资费用、抽采效果,论述了该矿煤层气高效开采利用手段可多方面考虑,如底抽巷、底抽钻场等可节约成本,解决了矿井瓦斯问题,为煤层气高效开采提供保障,同时对该矿瓦斯抽采方式、抽采方法、抽采规模等方面进行综合评价,指出煤层气开采面临的问题及抽采方式的优化选择。

Ximing coal mine is a large state-owned mine,at the same time it is a high gas mine,in recent years with strengthening the gas control,the mine gas drainage quantity increases gradually,so the coal bed gas resources high-efficient exploitation becomes important premise of low carbon development in the mine,this article through analyzing investment cost and extraction effect of the high drainage roadway,discusses that the means of coal bed gas efficient exploitation and utilization in the mine can be considered in many aspects,such as the floor roadway,bottom pumping drilling field and so on can save the cost,solve the problem of coal mine gas and provide guarantee for coal bed gas high-efficient mining,at the same time synthetically evaluates gas extraction ways,extraction methods,extraction scale and other aspects of the mine,points out the facing problems of coal bed gas exploitation and the optimal selection of extraction way.
