摘　　要：我国现开采的大部分煤层均具有高瓦斯、低透气性的特点,而采用水力压裂增透技术在煤层卸压增透方面发挥重要作用。为提高瓦斯抽采效果,腾晖矿结合2-202工作面的地质条件,基于水力压裂增透的原理,制定水力压裂增透工艺技术参数和布置方式,并对其应用效果进行量化分析。实践表明,采用水力压裂增透技术有效改善了该工作面瓦斯抽采效果,降低回采过程中的瓦斯含量,保障矿井的通风安全。Most of the coal seams in China are characterized by high gas and low permeability,and hydraulic fracturing and permeation technology plays an important role in unloading and increasing the permeability of coal seams.In order to improve the effect of gas extraction,combined with the geological conditions of 2-202 working face in Tenghui Mine,based on the principle of hydraulic fracturing to increase permeability,technical parameters and layout of hydraulic fracturing to increase permeability were studied,with its application effect.Practice showed that the use of hydraulic fracturing and penetration technology effectively improved the gas extraction effect of the working face,reduced the gas content in the recovery process and ensured the ventilation safety of the mine.
