【 摘 要 】

The underground coal preparation is a cutting-edge technology of the coal industry worldwide. This paper introduced the meaning of implementing the underground coal preparation, and the practical applications of underground mechanical moving screen jig, underground heavy medium shallow slot and underground air jigger. Through analyzing the main separation equipment and the advantages and disadvantages of three primary processes from aspects of process complexity, slime water treatment, raw coal preparation, etc., the difference among technology investment, construction scale, production cost and economic benefit is concluded.
