摘要
为了在有带式输送机的松软突出煤层巷道中高效抽采瓦斯,研制了具有高钻速、跨输送机施工能力、工艺适应性强等特点的ZDY2800LG型全液压钻机。文章介绍了该钻机的结构组成及主要参数,为检验钻机的性能,进行了工业性试验,通过地层摸索、寻求突破和高效钻进三个阶段详细介绍了钻机的工业性试验的整个过程,探索出了一条在松软破碎煤层中高效钻进的工艺方法。
In order to ensure the efficient gas drainage in belt conveyor roadway in soft outburst coal seam,ZDY2800 LG type hydraulic drilling rig is developed,which is of high drilling speed,the ability of drilling construction over belt conveyor, and strong adaptability for different processes. The structural composition and major parameters are introduced. The industrial test is also carried out,which is detailed from three stages including stratum groping,seeking breakthroughs and efficient drilling. The technology is an efficient drilling method in soft and broken coal seam.
