K2101综采背拉工作面回撤方案优选与收尾控制技术

摘要

In combination with the K2101 fully mechanized coal face mining roadway layout method, two working face withdrawal plans were proposed, and compared from the technical and economic aspects. By comparison, the withdrawal support from the middle lane is superior, before the end , K2101 face need to adjust the dip of mining direction , by taking a series of measures to control the glide of the transport, which has a higher guiding signiifcance for the safety and efifciency stopping and withdrawal.%结合K2101综采背拉工作面回采巷道布置方式，提出了两种工作面下段的回撤方案，并从技术和经济两个方面对回撤方案进行比较。经比较，从中间巷回撤支架较优。K2101工作面下段收尾前需进行调斜开采，通过采取一系列措施控制住了运输机的上窜下滑，对综采背拉工作面的安全高效收尾和回撤有较高的指导意义。
