井下煤和矸石液压式自动分选技术

Hydraulic automatic separation technology of coal and refuse in underground mine

针对当前煤矿生产过程中,煤炭出井后进行煤、矸分选,排放大量的矸石,介绍了一种井下煤、矸石自动分选方法,该方法利用煤、矸石的破碎力不同,采用液压旋转分选油缸对煤、矸石进行破碎性自动分选,实现煤炭开采过程中,在井下直接把矸石分选出来,将矸石留在井下。

According to the present mine production process,raw coal out off the mine will have a coal and refuse separation process.A great amount of coal refuse will be discharged.The paper introduced a coal and refuse automatic separation method in underground mine.The method has used the different breaking forces of the coal and rock.Hydraulic rotary separation cylinders can be used to make a breaking automatic separation of coal and refuse.In the coal mining process,coal refuse can be separated in underground min...
