日本近年来,由于高强度皮带的出现,个别地下矿山开始采用了斜井皮带运输机提升矿石,个别石灰石矿的外部长距离运输也开始采用皮带运输机。为便于集中控制和提高运输效率,实现装卸自动控制,采用斜井皮带运输的矿山均采用了井下一次破碎。日本生产的高强度皮带有:尼龙芯皮带,钢丝芯皮带和方钢芯钢绳皮带三种。特殊的还有:Butyl(I.I.R)皮带,可耐160～170℃的高温及可弯曲的钢板橡胶
In recent years, due to the emergence of high-strength belts in Japan, some underground mines have started to use inclined belt conveyor to lift ore, and the external long-distance transportation of individual limestone mines has also started to use belt conveyors. In order to facilitate centralized control and improve transport efficiency, to achieve loading and unloading automatic control, the use of inclined belt conveyor mine are used underground crushing. Japan's production of high-strength belts are: nylon core belt, steel core belt and square steel core rope belt three. Also special: Butyl (I.I.R) belt, resistant to 160 ~ 170 ℃ high temperature and bendable steel plate rubber
