煤与瓦斯突出矿井低透气性极软煤层深孔注水技术研究

Coal and Gas Outburst Extremely Low Permeability of Soft Coal Seam Deep Water Injection Technology

通过对义安煤矿低透气性煤层深孔注水技术的实践和研究,逐渐摸索出适合该矿的煤层注水技术和措施,从而达到了在地质条件复杂、瓦斯涌出量大、煤质极为松软等条件下降尘固帮、消减瓦斯、安全回采和掘进的目的,为职工的身心健康和矿井安全生产打下坚实基础。

Ngee Ann by low permeability coal seam deep mine water injection technology and the practice and research,and gradually worked out for the mine＇s coal seam techniques and measures to achieve in complex geological conditions,large amount of gas emission,coal and other very soft Solid help decrease dust conditions,reducing gas,mining and excavation safety purposes,for the physical and mental health workers and lay a solid foundation for mine safety.
