浅孔抽放技术在高瓦斯兴黔煤矿综采面的应用

分别对浅孔抽放机理和瓦斯运动特征进行了分析,并对浅孔抽放技术的参数设计、施工技术以及抽放工艺做了介绍,论述了该技术在兴黔煤矿综采工作面的应用,不仅解决了该矿瓦斯对工作面生产的制约和影响,同时也降低了该矿井回风流中的瓦斯浓度,在确保安全生产的同时,也带来了巨大的经济效益。由于安全可靠,操作简单,因此,近年来该技术在低透气性高瓦斯综采工作面得到了普及和应用。

Application on Draining Methane by Shallow Boreholes Technology in Full-mechanized Mining Face of High Gas Xingqian Coal Mine

The author analyses the mechanism and law of gas movement of draining methane of shallow boreholes respectively and introduces parameter design,constructing technology and drainage technology of draining methane of shallow boreholes,states the application of this technology on the full-mechanized mining face of Xingqian coal mine.It not only has resolved restraint and affect of the gas to production and reduced the gas density of wind tunnel,which ensures safety production,at the same time,it also brings huge economic benefits.Because this technology is safe and reliable,operation is simple,thus in recent years,this technology has obtained a large number of popularization and application on low permeability and high gas full-mechanized mining face.
