为解决采空区瓦斯大量涌出严重制约综采工作面生产的技术难题,针对岳城煤矿1302采煤工作面瓦斯浓度高的情况,基于煤炭开采时空接替、瓦斯抽采关系,提出适合高瓦斯煤矿瓦斯治理的井上下联合抽采采空区瓦斯技术模式.实践表明:该技术模式能够大幅度降低工作面瓦斯超限的威胁,有效抽采高瓦斯矿井采空区积聚瓦斯,提高了高瓦斯煤矿瓦斯抽采水平和安全生产效益.
為解決採空區瓦斯大量湧齣嚴重製約綜採工作麵生產的技術難題,針對嶽城煤礦1302採煤工作麵瓦斯濃度高的情況,基于煤炭開採時空接替、瓦斯抽採關繫,提齣適閤高瓦斯煤礦瓦斯治理的井上下聯閤抽採採空區瓦斯技術模式.實踐錶明:該技術模式能夠大幅度降低工作麵瓦斯超限的威脅,有效抽採高瓦斯礦井採空區積聚瓦斯,提高瞭高瓦斯煤礦瓦斯抽採水平和安全生產效益.

@@@@In order to solve the technical problem that the heavy gas emission may seriously restrict the production of a fully mechanized coal face,a combined gob gas drainage technology by both surface and underground boreholes was put forward for the high gassy mine in the light of the high gas concentration in 1302 working face in Yuecheng Mine and based on the relation between the time-space replacement and gas drainage during coal mining. The practice indicated that using this technology can greatly reduce the threat of disallowed gas concentration in the working face,effectively drain the accumulated gas in the gob of the high gassy mine and improve gas drainage level and safe production efficiency of the mine.
