矿山同其它企业不同,是直接开发自然资源的。开采矿体的空间和时间是有限的。矿山生产因资源和矿体空间大小的限制而表现作业地点的移动性和矿山寿命有限性,又因矿山寿命有限而产生矿山从建设到结束其生产规模不是恒定不变的。一般要经过三个阶段:从投产到达产的生产规模上升阶段,达产后生产规模稳定阶段,矿山后期生产规模下降阶段。生产发展的不同阶段,其经济效果是不相同的。
Unlike other enterprises, mines develop direct natural resources. The space and time to mine the ore body is limited. Due to the limitation of resources and the size of the ore body, mine production shows the limited mobility of the work site and the life of the mine, and the production scale of the mine from the construction to the end is not constant due to the limited mine life. Generally go through three stages: from the production to reach the production scale of the rising stage, after the completion of production scale stable stage, the late stage of decline in production scale of the mine. The different stages of production and development, its economic effect is not the same.
