一、引言在总路线的光辉照耀下和大跃进的形势鼓舞下,根据在苏联试验搪瓷溜槽使其在一定条件下部份地代替刮板运输机的经验,为我国煤矿大面积高产运动服务,并能节约钢材、节省电力、降低成本。于是自1958年即开始与北京、天津搪瓷厂等有关单位协作,研究、设计、制造、试验用于煤矿的搪瓷溜槽。在这过程中研究了瓷粉的性能,小批生产试制;而试验地点由小型煤矿扩大到大型矿井与手镐落煤、打眼放炮落煤、采煤康拜因落煤等落煤方法配合使用;而其长度亦由几节发展到几百节;在一个回采工作面的使用范围亦由局部发展到全部。实践证明,搪瓷溜槽用于煤
I. INTRODUCTION Inspired by the brilliance of the general route and the situation of the Great Leap Forward, China's large-scale and high-yielding coal mine service will be served according to the experiment of replacing the scraper conveyor partially with the test of the enamel chute in the Soviet Union under certain conditions. Save steel, save electricity, reduce costs. So since 1958 and Beijing, Tianjin enamel factory and other relevant units in collaboration with the study, design, manufacture, test for the enamel chute mine. In this process, the performance of porcelain powder and small-batch production trial were studied. The test sites were expanded from small coal mines to coal mines with large mines and hand-picks, ; And its length has also been developed from a few sections to hundreds of sections; in a mining face the scope of use also developed from the local to all. Practice has proved that the enamel chute for coal
