For the Jinhuagong Mine 2103 roadway mining through the F3 fault, the top plate with broken and delamination phenomenon, leading to the roadway roof support difficulty, support effect was poor, restricting the roadway safe and fast mining, collision wedge advance support + wire rod type advance support + grouting anchor and other joint support measures was adopted for roadway roof maintenance, the mining rate was increased to 4.5 m/d, and the top plate subsidence at the fault zone was reduced to less than 0.12 m, with significant application results.
