摘要
矿山企业经济效益的好坏与企业生产各环节的技术经济指标密切相关,其中原矿品位的高低对提高企业经济效益和最大限度地回收矿产资源起着决定性的作用。文中以此为前提,给出了以矿石品位表示的矿山企业盈亏平衡点和期望利润目标的计算公式,建立了市场经济条件下对边界品位实施动态优化的模型,为矿山企业的经济效益提高和资源的优化配置提供有效途径。
The economic performance of a mine is closely related to the technical and economic indices of the various links in the production chain.Moreover,the crude ore grade plays a decisive role in improving economic performance and recovering mineral resources to the full.On this condition,this paper presents the calculation formulas of mine enterprises＇breakeven point and expected profit target which are expressed in ore grade,and establishes the model to optimize the cutoff grade in a dynamic way under market economy.Thus,effective ways are provided for economic performance improvement and optimized allocation of resources for mine enterprises.
