贺西煤矿4号煤瓦斯抽采系统设计

Design of Gas Extraction System for No. 4 Coal in Hexi Coal Mine

为有效解决4号煤瓦斯涌出量大、通风困难,贺西煤矿根据瓦斯储量、可抽采量,从钻孔、封孔、管道负压计算、管道布置等多方面进行瓦斯设计,实现瓦斯综合治理,有效实现矿井安全生产。

In order to effectively solve the problem of large gas emission and difficult ventilation in No.4 Coal Mine,Hexi Coal Mine has carried out gas design from drilling,hole sealing,pipeline negative pressure calculation,pipeline layout and other aspects according to the gas reserves and recoverable amount,to achieve comprehensive gas control and effectively achieve mine safety production.
