Roof Stability of Rectangle Coal Roadway: In Light of Calculation of Compressive Bar Stability
The roadway roof is a key factor to the roadway stability. The analysis of roof stability is mainly based on numerical calculation and on-site observation, while the basic theory of the bearing mechanism is relatively weak. We have founded a critical pressure calculation model, on the theory of comp...
