Abstract: With the continuous promotion of intelligent mining and excavation in the country,situations of strained relations of mining and excavation continuity occurr from time to time,and the excavation and face laying engineering is difficult to meet the needs of pushing mining speed.In response to the problem of strained relations of mining and excavation continuity,the "110" construction method roof cutting and retaining roadway along goaf technology is implemented to eliminate isolation coal pillars in stoping roadways.The technology of retaining roadway along goaf can significantly improve coal mining efficiency,increase resource recovery rate,alleviate the tension of mining and excavation continuity,reduce mining costs,and reduce impact on environment.
