Support Technology for Soft Roadway With Multiple Cross-mining

According to the support technology problem for soft roadway with multiple cross-mining,based on the geological and mining two factors,the main reasons of surrounding rock deformation and the deformation law under the condition of dynamic pressure are analyzed,one support design idea with reinforcing rock mass,closing surrounding rock and high resistance yield support is put forward,the electromagnetic wave velocity and the surrounding rock of roadway convergence deformation monitoring show that the new design scheme can control surrounding rock deformation in an acceptable range when roadway cross mining again,the safety and efficiency of the mine production were ensured
