摘要
大同煤矿集团公司同忻矿井下输煤系统中,原设计在主井皮带尾安装一台MMD破碎机,用于大块矸石破碎。由于该处无法安装缓冲装置,造成煤流对皮带磨损;同时,因皮带胶面变薄,遇大块矸石或长条物料卡堵破碎机并与皮带接触,造成皮带纵撕事故。因此,提出变换破碎机位置的方案来解决这一问题。
In underground coal conveying system of Tongxin Mine of Datong Coal Mine Group, belt tail of main shaft install a MMD crusher in original design for large waste rock crushing. As there can＆#39;t install the buffer device, it causes belt wear by coal flow; at the same time, due to thinner belt surface, large waste rock or strip material plugs crusher and contacts with the belt, it causes longitudinal belt tear accident. Transformming crusher position to solve this problem is proposed.
