浅谈矿区贫瘦煤洗选方法研究

 郑州矿区所产原煤以贫瘦煤为主，属我国储量较低的稀有资源，具有高发热量、低硫、低磷、低挥发分、可磨性高等特点，是良好的动力煤、高炉用煤和化工用煤，被誉为绿色煤炭。由于质软、易碎等因素，长期以来被认为不能洗选加工。本文对该矿区贫瘦煤做了详尽的分析，提出了可行的选煤方法和选煤工艺。这一研究成果已经在郑州矿区付诸实施，打破了长期以来郑州矿区贫瘦煤不能洗选的一贯认识，为郑州矿区优化产品结构，延长产业链，实现循环经济作出了贡献。

Discussion on the Preparation of Meager-lean Coal in Zhengzhou Coal Mining Area

The meager-lean coal was the main raw coal product in Zhengzhou coal mining area, and it is a kind of scarce resource which is with high heat, low sulfur, low phosphorus, low volatile, higher grindability and other advantages among Chinese low reserves coals. It is known as ‘green coal’ because it is a kind of good power coal, blast furnace coal and chemical coal. Due to it is soft and fragile, it has been considered as not used to be prepared and proceeded. In this paper, the detailed analysis of the meager-lean coal in this area had been done, and the feasible method and technology of coal preparation were suggested. The research results had been implemented in Zhengzhou mining area, and it had broken the traditional mind that the coal in this area could not be washed. It is a great contribution for the optimization of the product structure, extendence of the industrial chain and achievement of the circular economy to the area.
