Local Weak Support Effect on the Stability of Surrounding Rocks in Deep Roadway
Coal mine roadway roof and sides often take strong support, and the floor support is weak or none support. Because of the high stress, roadway damage phenomena have occurred often, take reasonable repair plan is the key to the recovery project. Reasonable repair plan not only can effectively control the deformation of surrounding rocks, but also can reduce the maintenance cost. According to the surrounding rocks’ property and depth of roadway in Anhui Huainan Pan-III mine, using FLAC3D numerical simulation software, analysis of the effect on plastic zone, surrounding rocks stress and displacement under different floor support, and put forward the repair plan to this coal, the related research conclusions can provide reference for design and construction to similar engineering.
