为了解决矿体开采模式顶层设计的方向性问题,以矿山实际开采成本为基础,以开采年限内取得的总效益为目标函数,借助Analytica决策分析平台,建立矿体开采模式决策分析模型,计算不同生产能力、矿石价格、资源储量条件下有轨开采和无轨开采的开采总效益和年均效益,分析3种不同要素对矿山开采模式的影响;将模型用于云南锡业集团老厂分公司白龙井13-8号矿体的开采规划中,确定该矿体应选择无轨开采模式.
In order to solve the directional problem of top design about ore mining mode, based on the mine actual mining costs, the total benefits within the mine life was regarded as objection function, the ore mining mode decision analysis model was established with the Analytica software. The mining total benefits and annual benefit of rail mining and trackless mining on the conditions of different production capacity, ore prices and reserve were calculated, the impact of those factors to ore mining mode were analyzed. The model was applied in 13-8 ore body in the mining plan of Laochang branch Bailongjing production area, and the mine should choose trackless mining mode was determined.
