Abstract：There occurred problems of weak foundation of bolt and anchor cable, poor roof stability and unreasonable parameters in 921102 roadway heading face of Dashe Mine, and the roadway could not be used safely during the service period. According to the actual geological situation of the roadway, the comprehensive research method of theoretical analysis and field monitoring was adopted to carry out the combined support of bolt and anchor cable. The field industrial test showed that the support scheme reduced the displacement of the roof and floor of the roadway and the two sides, which could alleviate the deformation and failure of the surrounding rock of the roadway in the working face. It has reference significance for the surrounding rock control of the roadway in the slipway tunneling face under similar geological conditions.
