Numerical Analysis of the Recovery Rate Influence with Stowing Roadway Mining in Daizhuang Shengjian Coal Mine
Daizhuang Shengjian Coal Mine has dense village above the ground. Through analyzing the process of stowing roadway mining, the author establishes a numerical calculation model about the influence of recovery rate on the mining with stowing roadway. Under the condition of fixed mining width, simulating the impact of different coal pillar width on horizontal stress of coal wall, vertical stress of coal pillar and roadway roof, at the end, according to the result of the simulation, the ratio of extraction to reservation and coal recovery ratio can be determined
