深井开采经济合理深度的研究

Study on the economic limit depth of deep mine

以深井开采为对象， 分析了矿井生产吨煤费用与采深的关系， 建立了判断深井经济合理开采深度的数学模型． 以孙村煤矿为实例进行了研究， 得到了有益的结论．

After the relation between the production cost and mining depth in deep mining being analyzed, a criterion has been set up to determine economic limit depth of deep mine. Based on it, a useful conclusion is obtained for Suncun Coal mine.
