在我国埋藏量丰富的许多煤矿,现已普遍进入深井开采阶段,由于采煤工艺的需要,长距离、大运量的下运带式输送机已逐步成为井下的一种主要运输设备;但下运带式输送机的技术关键在于它的制动系统。目前国内已有几家工厂、研究所对下运带式输送机的制动技术进行工业性试验,为促进下运带式输送机更快 Many coal mines with rich reserves in our country have now generally entered the stage of deep well mining. Due to the need of coal mining technology, the down-going belt conveyors of long distance and large capacity have gradually become a major transportation equipment downhole. However, The key to the technology of the belt conveyor lies in its braking system. At present, there are several factories in China, and the Institute has conducted industrial tests on the braking technology of the down belt conveyor to speed up the down belt conveyor
