摘要: 针对新安煤矿煤层透气性低,松软破碎且瓦斯抽采衰减快的特点,基于高压水射流在煤岩体中扩展裂隙,改变应力场规律,重点分析了水力化措施瓦斯治理技术的层位影响,固定次序的必要性、优越性,利用顶板水力压裂和底板水力冲孔双重的卸压特征,通过优化设计钻孔参数,执行二次异层位综合水力化瓦斯治理措施,从而快速消突,实现瓦斯抽采达标。Abstract: Aimed at the features that the permeability of coal seam is low, soft and broken, fast gas extraction attenuation in Xin' an Coal Mine, based on water jet extension fracture in coal and rock and changing the stress field of law, we analyze the horizon effect of water jet measures gas control technology, the necessity and the advantages of the fixed order. Using the double pressure relief features of roof hydraulic fracturing and floor plate hydraulic punching, through optimizing design of drilling parameters, we perform the second different layers of an integrated water gas management measures to achieve the goal of quickly eliminating dangerous about coal and gas outburst, gas drainage reaching the standard.
