  • 摘要: 保德煤矿大盘区工作面采前瓦斯超前治理模式要求井下定向长钻孔能够沿煤层钻进3 000 m以上,针对现有技术装备在超长定向钻孔施工中存在滑动钻进困难、进水水路压耗大、有线随钻测量信号传输距离受限、冲洗液无法循环利用等问题,开发了煤矿井下基于螺杆马达水力加压和超长钻具正反扭转给进的滑动钻进减阻工艺、基于回转钻进倾角控制和侧钻分支的复合钻进轨迹控制技术,设计了低压耗进水水路系统、泥浆脉冲无线随钻测量系统和冲洗液净化循环系统,结合保德煤矿生产需要,完成了主孔深度3 353 m、孔径120 mm的顺煤层超长贯通定向孔。钻进效果表明:滑动钻进减阻工艺有效降低了给进力,显著提高了深孔滑动定向钻进能力;基于复合钻进的轨迹控制技术,保证了钻孔轨迹沿煤层定向延伸,并提高了钻进能力和钻进效率;泥浆脉冲无线随钻测量信号长距离传输稳定可靠,克服了有线随钻测量信号传输的局限性;井下冲洗液净化循环系统净化效果良好,实现了井下定向钻进冲洗液循环利用。研究成果对支撑煤矿大区域瓦斯超前治理、以孔代巷工程、水害防治及地质勘探等技术进步具有重要意义。
