选煤厂原煤质量的变化,影响设备的调整和选煤指标的主要因素之一,因此掌握控制原煤质量并预先进行估算是重要的。为此需要预测采区的原煤质量;结合采煤作业尽可能精确地估计入选煤的可选性;计算出一个选煤特性的估计值。 Coal quality changes in the coal preparation plant, the impact of equipment adjustment and one of the main factors in the selection of coal, it is important to master the quality control of raw coal and pre-estimated. To do this, it is necessary to predict the quality of the raw coal in the mining area; to estimate the feasibility of the selected coal as accurately as possible in combination with the coal mining operation; and to calculate the estimated value of a coal preparation property.
