【摘要】 针对国投哈密一矿原井田开拓方案存在的不足,结合影响井田开拓方案选择的各种因素,对原井田开拓方案进行了优化,根据煤矿建设项目的特点和生产实际,采用整体比选法中的费用现值法作为具体比选方法,通过对两个开拓方案从建设期、生产期及全寿命周期三个方面进行技术和经济分析比较,结果表明了优化后的开拓方案更为合理。整体比选法的应用,为合理确定井田开拓方案提供了有效的解决途径。更多还原

【Abstract】 In light of the deficiencies of the original minefield development scheme for the SDIC Hami No. 1 Mine,combined with various factors affecting the selection of minefield development schemes,the original minefield development scheme was optimized. According to the characteristics of the coal mine construction project and the actual production,the present value method of the overall comparison method was adopted. Through the technical and economic analysis and comparison of the two development schemes from the three aspects of construction period, production period and life cycle, it shows that the optimized development plan is more reasonable. The overall comparison and selection method is an effective solution to reasonably determine the field development plan.更多还原
