摘要
本文针对九龙矿地面水射流径向水平破煤瓦斯治理技术成功应用进行介绍,并对地面主孔数量和位置确定、高压水射流煤层径向射孔方法和作用,压裂方法与目的、压裂监测方法、治理效果进行论述。该技术的成功应用,为矿井瓦斯治理开创了一条全新技术路线,并在相关矿井得到推广应用。
This paper introduces the successful application of surface water jet radial horizontal coal breaking gas control technology in Jiulong Mine,and discusses the number and location of main holes on the ground,the radial perforation method and function of high pressure water jet coal seam,fracturing method and purpose,fracturing monitoring method and treatment effect.The successful application of this technology has created a new technical route for mine gas control,and has been applied in related mines.
