摘要/Abstract

摘要： 依据矿山生态足迹定义，基于生态足迹模型，建立了生态成本分配模型，将生态成本分摊到某露天矿的开采成本中，从生态的角度出发，将外生成本内生化进行最终境界的设计，进行境界优化迭代，得到考虑生态成本下的最终境界，并分析了生态成本对最终境界的影响。优化结果表明：考虑生态成本下圈定的矿山最终境界缩小了11.29%；开采出的矿岩量较未考虑生态成本下圈定的最终境界的矿岩量少，矿石量减少15.38%，岩石量减少了30.45%；将矿山生态成本内生化圈定的境界得到的净利润，比未考虑生态成本圈定的境界，并以该境界核算出对应的生态成本进而得到的矿山综合利润多出了13.46%，生态成本内生化对最终境界优化有很大影响。

Abstract: Based on the ecological footprint definition and model,the distribution model of ecological costs is established,so as to allocate the ecological costs into mine production costs of an open-pit mine.The ultimate boundary is designed transforming the exogenous costs into endogenous costs from the perspective of ecology.Through the iteration of ultimate pit optimization,the ultimate boundary is obtained by considering ecological costs,besides that,the influence of ecological costs on the ultimate boundary is analyzed.The optimization results show that:the ultimate boundary delineated by considering ecological costs is reduced by 11.29%,quantity of ore and rock of the ultimate boundary delineated by considering ecological costs are reduced by 15.38% and 30.45% respectively,compared with the ones of the ultimate boundary without considering ecological costs.The net profit of the ultimate boundary delineated by transforming the ecological costs into endogenous costs is raised by 13.46%,by comparing with the mine comprehensive costs by the ecological costs calculated by the ultimate boundary without considering ecological costs.The above analysis results show that the influence of the transforming ecological costs into endogenous costs on ultimate boundary is significant.
