【摘要】：针对当前松软突出煤层钻进用大扭矩钻机转速低、高转速钻机采用分体式结构搬迁使用麻烦等不足,结合松软突出煤层瓦斯抽采钻孔施工需要,研制了一款高转速、长行程、履带行走式的跨输送带螺旋钻机;开发了高转速动力头、长行程给进装置、吊装提升装置和具有保护功能的液压回路等关键技术;在晋城王坡煤矿现场试验结果表明:该钻机结构设计合理、液压系统先进、搬迁使用方便、钻进效率和钻孔成孔深度高,在松软突出煤层中具备200 m深的瓦斯抽采钻孔施工能力。
[Abstract]:In view of the shortcomings such as low rotational speed of large torque drilling rig for drilling in soft outburst coal seam and trouble of moving and using high rotating speed drilling machine with split structure at present, a high speed and long stroke has been developed according to the need of gas drainage drilling in soft outburst coal seam. The key technologies such as high speed power head, long stroke feeding device, hoisting device and hydraulic circuit with protective function are developed. The results of field test in Wangpo Coal Mine of Jincheng show that the drilling rig is reasonable in structure design, advanced in hydraulic system, easy to move and use, and has high drilling efficiency and drilling hole depth. In the soft outburst coal seam, it has the construction ability of 200 m deep gas drainage borehole.
