摘　　要：主要分析了绳索取心钻进工艺在煤田沉积岩地层钻探中的应用方法与存在问题。煤田沉积岩绳索取心钻进大幅度提高了效率和质量,减轻了工人的劳动强度,降低了成本,加快了勘探进度,但是煤系地层的自有特性还有很多制约绳索取心钻进地方,通过不断地在技术上进行研究与探索,必将使绳索取心钻进在煤田钻探的应用中上一个新的台阶。This paper mainly analyzes the application method and existing problems of rope core drilling technology in coalfield sedimentary rock formation drilling.Rope core drilling for coalfield sedimentary rocks has greatly improved the efficiency and quality,reduced the labor intensity of workers,lowered the cost and accelerated the exploration progress.However,there are still many restrictions on rope core drilling due to the self-owned characteristics of coal measures strata.Through continuous research and exploration in technology,rope core drilling will surely take a new step in the application of coalfield drilling.
