中煤提精技术落地盘州 助力煤炭资源“吃干榨净”

Core Viewpoint - The coal industry is advancing supply-side structural reforms and green low-carbon transformation, focusing on efficient and clean utilization of low calorific value coal and coal slurry to minimize resource waste and environmental impact [1][2]. Group 1: Project Overview - The Changneng low calorific value coal comprehensive utilization project occupies approximately 275 acres with a total investment of 600 million yuan, planned in three phases with designed annual processing capacities of 500,000 tons for phase one, 1 million tons for phase two, and 1.5 million tons for phase three [1]. - Phase one of the project has been completed and is operational, while construction of phase two is progressing rapidly [1]. Group 2: Technological Innovation - The project utilizes a proprietary "low-quality coal de-ash and quality enhancement deep processing technology," achieving a coal recovery rate exceeding 50%, with resource utilization efficiency improved by over 30% compared to traditional methods [2]. - The technology requires only 1.5 to 2 tons of medium coal or 2.5 to 3 tons of coal slurry to produce 1 ton of premium coal [2]. Group 3: Environmental Impact - The project incorporates advanced coal slurry water treatment and water recycling systems, achieving a closed-loop operation with no wastewater discharge, thus minimizing water resource consumption and ensuring zero pollution [2]. - The project plans to establish a new building materials project with an annual output of 500,000 tons and a soil remediation project with an annual processing capacity of 1.5 million tons, effectively utilizing high-ash tailings generated from premium coal extraction [2]. Group 4: Economic Value - Upon full production, the project is expected to convert 3 million tons of underutilized medium coal and coal slurry into over 1.7 million tons of high-value premium coking coal, generating an estimated economic value exceeding 2 billion yuan annually [2].
