Study on the Upper Limit of Roof Failure in Soft Rock Roadway

Study on the Upper Limit of Roof Failure in Soft Rock Roadway

This study addresses the issue of large deformation in soft rock roadways, using the 50213 tailgate of Guantun Coal Mine as a case study. Field investigations were conducted to assess the condition of roadway bolts, anchor cables, and the internal damage characteristics of the surrounding rock. The...
