胶带输送机在煤矿井下原煤运输中发挥着重要作用,但只能铺设在笔直并无较大起伏的环境中,这样就给大量推广使用造成了障碍,特别是沿煤层走向掘进的各采煤工作面的下运输道,多为起伏不平,有时起伏还较大,甚至两端高,中间低,为长走向综采或普采工作面在设备配备上造成了一定困难。例如范各庄2274综采面下运输道就是一个典型例子,如图 Belt conveyors play an important role in the transportation of raw coal in coal mines, but can only be laid in a straight and undulating environment, thus causing obstacles to a large number of popularization and use, in particular, coal mining heading along coal seams Under the surface of the transport lane, mostly undulating, and sometimes fluctuating is also larger, or even high at both ends, the middle of low, for a long move to fully mechanized or general mining face in the equipment equipped with some difficulties. For example, Fangezhuang 2274 fully mechanized mining area under the carriageway is a typical example, as shown
