以往三十年,欧洲煤矿生产广泛实行机械化。机械化技术所达到的精确、完美程度令人惊叹不已。一、前言过去三十年里,人们致力于实行工作面附近生产机械化,尤其是致力于实行运输、采煤机械化,同时还致力于实行支护机械化。在支护机械化方面已发展到使用掩护式支架。与此同时,在巷道掘进机械化方面也取得了引人注目的成果:从设计液压装载设备到设计部分断面掘进机及全断面掘进机,
In the past three decades, mechanization of coal production in Europe has been extensively implemented. The precision and perfection achieved by mechanization is amazing. I. Introduction In the past three decades, people were committed to the mechanization of production in the vicinity of work surfaces, and in particular to the mechanization of transportation and coal mining while also devoting their efforts to the mechanization of support. In the support mechanization has been developed to use the shield bracket. At the same time, remarkable achievements have also been made in roadway mechanization: from designing hydraulic loading equipment to design of section boring machines and full-face boring machines,
