摘要
矿井瓦斯是威胁煤矿安全生产的有害气体,为了减少和消除矿井瓦斯对煤矿安全生产的威胁,利用机械设备和专用管道成负压,将工作面、采空区涌出的瓦斯抽出来,排放到其他安全地点。介绍了寸草塔二矿瓦斯抽放系统的布置以及通过对实测数据分析,探索ZWY-270/355-G型瓦斯抽放泵在条件相似工作面使用时的有效瓦斯抽放半径。
Mine gas is remove its threat on mechanical equipment and was discharged to harmful,and is threatening the safety production mine gas safety production in coal mines,using and dedicated pipeline ,the gas exists in working the other safe places.The paper mainly introduced of coal mine, in order to reduce and the the negative pressure caused by face and mined-out area was drained the arrangement of gas drainage system of Cuncaota No.2 Coal Mine, the measured data was also analysed,to explore the effective radius of gas drainage for ZWY - 270/355 - G type gas drainage pump on working face with similar conditions.
