Optimization design of bolt-mesh-cable support for working face transportation roadway in close distance coal seams
CHEN Qing-feng
Abstract：Aiming at the high labor intensity and slow driving rate under the original "bolt-mesh + joist steel shed" support in Jinda Coal Mine,an optimization supporting scheme design of "bolt-mesh-cable" was proposed according to the results of geological mechanics test,which uses combined bolting system of extensible bolt and supplement support of cable.Simulation analysis of FLAC3D showed that,with the application of bolt-cable combined support system,the surrounding rock deformation of 10107 transportation roadway was effectively controlled,the supporting effect was significant,and the roadway was used safely during production.
