摘要
鉴于年产超1 000万吨的大型水泥原料矿山和砂石原料矿山具有投资额大、运营费用高,矿区占地面积大、开采深度高,开采技术条件复杂,矿石质量变化大,对周边环境及配套条件要求高等特点,结合大型矿山的设计,提出了大型矿山前期矿点的选择应充分评价矿区及周边环境、矿石品质、矿山储量折减程度、矿山地质条件、开采条件、可综合利用资源等重要技术因素;同时,应对大型矿山进行合理分区开采规划、合理平衡采矿与剥离的超前关系、合理选择开拓运输系统、科学确定溜井平硐系统参数、合理配置开采设备、充分利用采空区排废、合理设计排废场等节能降耗措施,为大型矿山建设提供了技术应对方法.
Abstract
Large-scale cement raw material mines and sand-gravel raw material mines with an annual output of more than 10 million tons have the characteristics of large investment,high operating costs,large mining area,high mining depth,complex mining technical conditions,large changes in ore quality,and high requirements for surrounding environment and supporting conditions.Combined with the design of large-scale mines,it is proposed that the selection of large mines in the early stage should fully evaluate the important technical factors such as mining area and surrounding environment,ore quality,mine reserves reduction,mine geological conditions,mining conditions,and comprehensive utilization of resources.At the same time,it is necessary to carry out reasonable mining by areas,reasonably balance the advanced relationship between mining and stripping,reasonably select the development and transportation system,scientifically determine the parameters of the chute system,rationally allocate mining equipment,make full use of mining pit with waste filling,and rationally design waste dumps,which provide technical measures for large mine construction.
