一、前言近年来,日本煤矿向深部过渡的趋势日益明显,保证深部采煤工作面周围巷道维护问题,是关系到深部采煤安全和生产两方面的最重要的问题,需要对这方面进一步采取措施。通过巷道支护的刚性化来防止支架变形,普通过刷帮作业保证巷道所需断面积,则是巷道维护措施中的最重要的问题。不过,过去在这方面未作过机械化的偿试,其基本原因是井下作业内容比较复杂,

I. Introduction In recent years, the trend toward the deep transition of Japan’s coal mines has become increasingly evident. Ensuring the maintenance of roadways around deep coal mining faces is the most important issue that concerns both deep-seated coal safety and production and needs to be further taken in this regard Measures. Through the rigidity of roadway support to prevent the stent deformation, the general brush work to ensure the required cross-sectional area of ​​the roadway is the roadway maintenance measures in the most important issue. However, in the past, no mechanized reimbursement was made in this respect. The basic reason for this is that the underground operations are complicated,
