摘　　要：石煤型钒矿含矿岩层矿石硬度小,节理发育,开采难度大,资源利用率低。通过采用中深孔落矿分段空场法采矿,回收了大量的矿柱、并对原有采矿方法无法回采的破碎矿段也进行了安全高效开采,对于石煤型钒矿石大规模开采积累了诸多的实验数据和科学依据,为以后矿山安全高效生产打下了良好的基础。The ore hardness of ore-bearing strata in stone coal vanadium mine is small,the joints are well developed,the mining is difficult,and the resource utilization ratio is low.A large number of ore pillars have been recovered and the broken ore segments which can not be recovered by the original mining method have been mined safely and efficiently by adopting the medium-length hole caving and layering open stope method,a lot of experimental data and scientific basis have been accumulated for large-scale mining of stone coal vanadium ore,which lays a good foundation for safe and efficient production.
