摘要
深部松软巷道破坏给矿井正常生产及工作人员的安全带来了严重威胁,以桃园煤矿7244工作面机巷为例分析了深井松软巷道的破坏机理,提出锚注支护方案,并通过实践证明了该方案技术及经济合理性,同时对相似地质条件下松软巷道围岩控制也具有一定的借鉴意义。
The failure of deep soft-rock roadway poses a serious threat to normal production and workers＇safe‐ty .Taking the machinery roadway at 7244 working face of Taoyuan Colliery for example ,the authors propose the bolt-grouting support scheme by analysis of the failure mechanism of deep soft -rock roadway ,which has been proved to be of technical and economic rationality by practice and provide a reference for the soft surround‐ing rock control under similar geological conditions .
