According to the characteristics of difficult supporting and low safety of broken-tapes in coal roadway, we should apply the new technology of the bolt- injection supporting. It shown that the technology of controlled broken-tapes is workable, economic and rational, and is obtained obvious results. This paper suggests that it is worth popularizing and applying in the construction connecting with practical case.
