Analysis of classification and utilization of coal gangue in Yonglong Mining Area
Regarding the coal gangue in the Yonglong mining area,which has basically no calorific value and no utilization value,it is divided into different particle sizes and used for power generation,brick making,building materials,road paving,underground filling,etc.according to different calorific values.This has realized the transformation of resources in the mining area from waste to treasure,promoted local employment,and achieved a win-win situation in economic,social and ecological benefits.However,its comprehensive utilization is only at the lowest end of the value chain.Therefore,during the period from the end of the"14th Five-Year Plan"to the"15th Five-Year Plan",attention should be paid to the basic theoretical research of coal gangue,responding to national policies,developing new-quality productive forces based on local conditions,increasing the added value of products,and promoting the transformation and upgrading of the enterprise's industrial structure.
