100T分体型车载钻机穿越采空区试验研究

Experimental Study on 100T Split Type Truck-mounted Drillling Rig Passing through Goaf

100T分体型车载钻机由钻机车和动力泵站组成,动力泵站采用标准集装箱吊装规范,方便运输吊装,其封闭箱式的设计隔音降噪,克服了元部件过去因直接暴露在外部环境下导致的寿命缩短和后期维护工作量增加的问题,同时100T分体型车载钻机技术性能先进、制造精良、质量可靠,具有工艺适应性强、移动搬迁迅速、占地面积小的特点,具备施工孔深500 m(孔径Ф711 mm)和孔深2500 m(孔径Ф153 mm)的钻孔能力,能够满足地面矿山应急救援和煤层气开发需要。在山西晋城寺河矿区进行了现场工业性试验,顺利完成了一口终孔直径Ф171.5 mm、井深1096 m穿越采空区的L形煤层气生产井。试验中未发生任何机械故障,试验结果验证该100T分体型车载钻机具备较强的工艺适应性和稳定性。

The 100T split type truck-mounted drilling rig consists of a drilling locomotive and a power pump station.The power pump station adopts standard container hoisting specifications to facilitate transportation and hoisting.Its closed box design,sound insulation and noise reduction,overcomed the problems of shortening the service life of components and increasing the later maintenance workload caused by direct exposure to the external environment in the past.At the same time,the 100T split type truck-mounted drilling rig has advanced technical performance,excellent manufacturing,reliable quality and strong process adaptability It is characterized by rapid movement and small floor area,and has a construction hole depth of 500 m(hole diameterФ711 mm)and hole depth 2500 m(hole diameterФ153 mm),which can meet the needs of surface mine emergency rescue and coalbed methane development.The field industrial test was carried out in Shanxi Jincheng Sihe mining area,and a crossing goaf L-shaped coalbed methane production well with a final hole diameter ofФ171.5 mm and a well depth of 1096 m was successfully completed.No mechanical failure occurred during the test.The test results verify that the 100T split type truck-mounted drilling rig has strong process adaptability and stability.
