井下大巷采用矿车运输的煤矿,常遇到矿车清底的问题。徐庄矿井下大巷运输采用600毫米轨距,容量为1吨的矿车,自投产以来,由于没有有效的清车手段,使矿车积煤逐渐增多,严重影响了运输效率。曾作过统计,1000辆/次仅运煤400～500吨,白白浪费了大量的电力,机械和人力。随着生产规模的扩大,运输跟不上的矛盾日益突出。为了提高矿车的实际装载能力,扭转运输跟不 Underground mine car transport using coal mines, often encounter the problem of clear car bottom. Xuzhuang mine roadway transport using 600 mm track gauge, a capacity of 1 ton of tub, since commissioning, since there is no effective means of clearing the car so that the accumulation of coal accumulating, seriously affecting the transport efficiency. Statistics have been made, 1000 / only coal 400 to 500 tons, wasted a lot of electricity, machinery and manpower. With the expansion of the scale of production, the contradiction between the transportation and the transportation has become increasingly prominent. In order to improve the actual loading capacity of the tub, to reverse the transport and not
