在潘三选煤厂的实际配煤流程中,可以利用现有工序标准的定量数据建立一个合理准确的模型,并通过一个实例进行统筹分析。这个模型在满足产品热值要求的前提下,实现末煤洗选比例有不同的取值方案。通过建立模型并分析,可以为决策者提供理论支持,使其合理组织生产,利用最低的入洗比例达到最佳的产品配煤效果。同时也为组织者提供数量标准作为参考,及时修正关键环节存在的问题。

In the actual coal blending process of Pansan Coal Preparation Plant, a reasonable and accurate model can be established by using the quantitative data of the existing process standards, and an overall analysis is carried out through an example. This model can consider that under the premise of meeting the requirement of product calorific value, the ratio of final coal washing can have different value schemes. Through the establishment and analysis of the model, it can provide theoretical support for decision-makers,so that they can organize production reasonably and achieve the best blending effect of products with the smallest washing proportion. At the same time, it also provides the quantity standard as a reference for the organizer to correct the problems existing in the key links in time.
