摘要
以国有重点煤矿原煤成本的历史数据为基础,对吨煤成本及其构成进行分析,旨在揭示我国煤矿成本水平的变化趋势及成因.分析结果表明:我国煤矿的吨煤成本呈总体上升的趋势,而国家的政策调控、物价上涨、人工成本的增加、煤炭价格的影响是产生这种趋势的主要原因.
Based on the historical cost data of China key state-owned coal mines, studied the unit cost of coal mining and its component. This composition revealed that China unit cost of coal mining was rising during the few decades. While the causes are various, such as policy of operation, pricing variation, labor cost, etc.
