煤炭灰分、发热量、单位面积产量与煤矿经济效益关系的探讨

Discussion of relationships among ash content of coal, calorific value, the yield per unit area and economic benefits of coal mine

对于企业来说,煤炭的单价及产量不仅影响着煤炭企业的经济效益,更关系到煤炭企业的生死存亡。单位面积产量决定了企业的原煤产量,而灰分、发热量又从质上决定了煤炭的价格。该文通过对灰分、发热量与单位面积产量之间平衡点的研究,来实现煤炭企业经济效益最大化。

To the enterprise, unit price and yield of coal not only affects the economic benefits of coal enterprises, but also related to the coal enterprises of vital importance. The yield per unit area has decided enterprise＇s output of raw coal, ash content, calorific value and from quality determines the price of coal. In this paper, through the study on the balance point between calorific value and ash, the yield per unit area, to realize the maximization of economic benefit of coal.
