首先通过理论分析,对开滦煤矿生产中洗煤、选煤两步工艺做最佳数学模型建立;然后分别阐述了精煤回收率的最大获得值γmax的数值模型建立、最佳经济效益Yx的数学模型的建立;最后推导出生产的最佳数学模型。并结合开滦炼焦厂、选煤厂的实际生产计算出煤的最佳经济收益。
First of all, through theoretical analysis, the best mathematic model of coal washing and coal preparation in Kailuan coal mine production is established. Then the numerical model of the maximum recovery γmax of coal recovery is established respectively. The mathematical model of the best economic benefit Yx The establishment of model; and finally deduce the best mathematical model of production. Combined with the actual production of the Kailuan coking plant, coal preparation plant to calculate the best economic benefits of coal.
