摘　　要：在极易冒落的复合顶板条件下,通过在破工序中采取轻割浅割、留顶帮人工挖刷等多种手段减轻对顶板的松动破坏,在支护工序中采取加大锚梁网支护本身的密度和采用联合支护弥补单一支护方式的不足等方法的探索,成功解决了逮复合顶板综掘的四大技术难题,而且应用效果良好。On the condition of compound roof which is droped easily, in breaking up procedure, incise it gently and slowly, put apart roof and side and then dig it by hand, and so on, we use them mitigating breakage to roof. In support procedure, we increase itself consistency of sustentation with anchor- girder- wire netting, adopt united support to offset shortage of simplex support. By aforementioned exploration, not only succeeded to solve four big technical difficult problems of integrative mechanisation tunneling technic under coal bed with compound roof, but also the application effect was good.
