摘要
采矿设计中,矿体产状变化大,采矿方案的选择极难解决。结合赵普白钨矿段开采条件实际,充分考虑其影响因素,设计了一套合理可行的采矿改进方案,能确保当矿体厚度大于5 m且倾角小于50°时,矿石能借助其自重进行溜矿。实践表明,该方案采矿成本较类比矿山节约近16元/t原矿,作业安全性好,生产能力大,对同类复杂矿体开采的矿山具有较好的指导意义和推广运用价值。
In mining design,orebody occurrence varies greatly,and the selection of mining scheme is very difficult to solve.A reasonable and feasible mining improvement project is designed combining with the actual mining conditions of Zhaopu scheelite ore block with the full consideration of its influencing factors,it can ensure that ore can be passed by its self-weight when the thickness of ore body is large than 5 m,and the dip angle is less than 50°.The practice shows that comparing of the above mentioned and the similar schemes,the mining cost can be saved nearly 16 yuan/t per raw ore with good operation,safety and large production capacity,therefore it has better guiding significance,promotion and application value to the similar complex ore body mining.
