摘要
煤矿井下生产出来的矸石一直向地面矸石山排放,不但占用耕地面积、污染环境,而且还经常出现煤矸石自燃、山体垮塌等危险,也不利于有用物资的回收。矿内输送带运输矸石排放系统有效地解决了这些难题。
The gangues dug out in the coal mine has been discharged directly to ground waste hill, and this is not only occupy the cultivated land, pollute the environment, but also frequently result in the such risks as self-combustion of the gangue, land slide, etc. Besides this is unfavorable to the recycle of the useful materials. The discharge system for the belt conveyance of the waste rock in the mine well solves these problems.
