1前言伴随井下采掘现场向纵深部发展,运输距离越来越长。同时由于采掘现场向集中化、大型化发展,运输距离将更为加长。必须和这种趋势相对应,对于采用胶带输送机的运输技术,也进一步增大了长距离和大运输能力的重要性。从前以一个驱动部为主流的方式,其驱动部在一个场所,动力集中,驱动部电机功率大,需要有大强度的高耐张力的输送胶带。此外,采用多段化方式则使驱动部分散 1 Preface Along with underground mining site to the development of deep, longer and longer transport distance. At the same time as the mining site to the centralized, large-scale development, transport distance will be even longer. This trend must be commensurate with the importance of transport technology using belt conveyors that further increases the capability of long distances and large transport. In the past, one drive unit was the mainstream. The drive unit was concentrated in one place and the power of the motor in the drive unit was large. Therefore, a strong tensile tape with high tensile strength was required. In addition, the use of multi-segment approach is to drive scattered
