摘　　要：煤矿井下随钻测量技术在瓦斯灾害防治、水害防治、隐蔽地质灾害探查等方面发挥着不可替代的作用,是煤矿井下钻探施工由“轨迹不可控”到“精确定向”的关键技术,大幅提升了我国煤矿井下灾害防治水平。介绍了随钻测量技术的原理和技术类型,回顾了煤矿井下随钻测量技术的发展历程,对有线随钻测量技术、泥浆脉冲无线随钻测量技术、电磁波无线随钻测量技术等代表性技术成果及其实际应用情况进行了详细阐述。基于新形势下智慧矿山、透明矿井建设需求,围绕煤矿灾害防治智能钻探,从“近钻头随钻测量”“定向长钻孔+地质探测”“定向长钻孔+瓦斯探测”等方面,展望了随钻测量技术的发展趋势。Measurement while drilling(MWD)technology plays an irreplaceable role in gas disaster prevention and control,water disaster prevention and control,hidden geological disaster exploration and so on.It is the key of coal mine underground drilling construction to change from“uncontrollable trajectory”to“precise orientation”,which greatly increases the level of disaster prevention and control in Chinese coal mine.This paper introduces the principle and technical types of MWD technology,reviews the development of MWD technology in underground coal mines,and expounds the representative technical achievements and practical applications of wired MWD technology,mud pulse wireless MWD technology and electromagnetic wave wireless MWD technology in detail.Based on the construction needs of smart mines and transparent mines under the new situation,the development trend of MWD technology is prospected from the aspects of“near-bit MWD”,“directional long drilling+geological exploration”,“directional long drilling+gas exploration”and so on,centering on the intelligent drilling of coal mine disaster prevention and control.
