我国第一台二米落地式双绳摩擦提升机在河南省巩县大峪沟煤矿诞生。这台提升机是由洛阳矿山机械研究所、洛阳矿山机器厂、巩县大峪沟煤矿共同改制并试验成功的。河南省巩县大峪沟煤矿是一九五八年兴建的小型煤矿,开采方法比较落后,机械化程度不高,二十多年来虽经多次大的技术改造,生产面貌也大为改观,原煤产量比原设计增长了七倍多,但仍满足不了形势发展的需要。一九 China’s first two meters floor-mounted double-rope friction hoist in Gong County, Henan Province Dayu ditch mine was born. This hoist is Luoyang Mining Machinery Institute, Luoyang Mining Machinery Factory, Gongxian Dayugou coal mine co-restructuring and successful trial. Dayuogou Coal Mine, Gong County, Henan Province, was a small coal mine built in 1958. Its mining methods are relatively backward and the degree of mechanization is not high. Over the past 20 years, despite its large-scale technological transformation, its production landscape has also been greatly improved. Raw coal output more than seven times more than the original design, but still can not meet the needs of the situation. One nine
