工作面输送机的发展采煤工作面输送机于1902年开始在英国煤矿使用,当时的输送机为布莱刻特公司的带环刮板输送机。从1906年起,即受到工作面皮带输送机的强烈挑战。后来,振动式输送机也相继问世。到1947年英国煤矿实行国有化时,工作面输送机的总台数已达8500台,其中64%为皮带输送机;18%为链板输送机;另外的18%为振动输送机。 Face conveyor development Coal face conveyors began their use in British coal mines in 1902 when they were delivered by Bradley’s belt loop scraper conveyors. From 1906 onwards, it was strongly challenged by the face belt conveyor. Later, vibration conveyor also come out one after another. By the time of the nationalization of British coal mines in 1947, the total number of working face conveyors had reached 8,500, of which 64% belted conveyors, 18% were chain conveyors and the other 18% were vibratory conveyors.
