摘要
阿尔哈达矿区矿体形态复杂,厚度发生较大变化时空场法采矿往往存在许多问题。通过优化采矿设计研究,降低了采切比,既节资降耗又安全高效,促进三级矿量平衡,解决了膨胀夹缩矿体空场法采矿成本高的难题,为本矿山开采复杂矿体提供了技术支持,也为同行业类似矿山提供技术借鉴。
The forms of ore bodies in A＇erhada Mine are complex, and many problems often occur when the thickness changes largely. Through optimization design study on open-stope method, the mining-cutting ratio is reduced and then the cost and consumption are reduced, and the efficient is high and safe, three-grade reserve is promoted. The study result can provide technical support and reference for mining of complex ore bodies.
