Study on Optimal Roadway Bolt Supporting Scheme with Easy-Breaking Roof
The roadway bolt supporting with easy-breaking roof is a complex systematic problem, and the success or failure of roadway bolt supporting is determined by pre-stress level in some sense. To well recognize the bolt supporting effect under different pre-stress level, the laneway which has cracky roof is taken to systematically analysis the changing situation of roadway’s stress and deformation by using 2-dimension finite difference code -FLAC2D.The theoretical analysis and practical observation results show that high pre-stress scheme is the best way to improve the roadway surrounding rock strength and to control the cracky roof roadway’s deformation. It has some references to engineering design, construction and maintenance for similar soft rock mines.
