摘要
随着采煤机械化程度和采煤技术的不断提高,采出的煤里混入了大量矸石,基于现有煤矸石分选技术的不足,介绍了一种新型井下煤矸石自动分选方法,该方法利用煤和矸石破碎力的不同进行选择性破碎,可以将大于50mm的煤和矸石在井下直接进行分离。
As the coal mining mechanization and coal mining technology continues to improve,the mined coal with large quantity of gangue,with the deficiency of coal gangue separation technology has existed,a kind of automatic separation method of coal gangue is proposed,it can be selective breaking according to the different Of breaking forces on the coal and gangue,the size more than 50mm of coal and gangue can be direct separated in the underground.
