具有刚性联系的双滚筒驱动带式输送机是井下采区最常用的运输设备，但两个滚筒磨损不均问题一直困扰着广大矿山工作者。本文对这一问题进行了分析计算，并提出了一些新的见解与解决方案。 Dual-belt driven belt conveyors with rigid linkages are the most commonly used transport equipment for downhole mining, but the uneven wear of both cylinders has plagued mine workers. This paper analyzes and calculates this problem and puts forward some new opinions and solutions.
