煤矿风井地面瓦斯抽采技术及综合利用技术研究应用

Study and Application of Surface Gas Drainage Technology and Comprehensive Utilization Technology in the Coal Mine Air Well

针对煤矿生产中涌出的瓦斯威胁着工作面的安全生产,以马兰矿井为研究对象,在分析该矿井地质、煤层、瓦斯涌出情况的基础上,选择斜向钻孔的瓦斯抽采方式,并将所抽采处的瓦斯用于矿井的发电,同时完成了瓦斯发电站设备及系统的选型。

In view of the gas emission in coal mine production threatening the safety production of the working face,taking the Malan Mine as the research object,on the basis of analyzing the geological,coal seam and gas emission situation of the mine,the gas drainage mode of the inclined borehole is selected,and the gas in the drainage area is used for the power generation of the mine,and the equipment and system selection of the gas power station is completed.
