摘要：
Roof accidents have always been one of the most frequent and serious casualty accidents. The researched roof on tailentry D302 in Xinyuan Colliery is compound mudstone with 10m thick. During excavation of this roadway the collapsing length amounts to about 15m, which has a serious influence on the roadway safety. As a result, the combined support system of cable truss is put forward, then the support parameters are determined by numerical simulation and the final scheme is applied. The cable truss system was proved to play an important part in the scheme and the design method was reasonable and effective.
