英国国际采矿协会有限公司主席布伦劳德等人,在西德《幸福》杂志一九八一年第九期上发表了一篇题为“英国采煤工作面机械化”的文章。文章分析研究了英国从1960年到1980年工作面机械化的效果,提出了一个很值得深思的问题,即是否机械化程度越高越好?在这二十年内,英国为煤矿付出了大量资金,主要用于工作面机械化,使机械化工作面产量从占总产量的37.5%提高到了94%。但是,大量统计数据证明,上述变化并没有使煤矿取得最佳利润。
Blenderder, chairman of the British International Mining Association Limited, published an article entitled “mechanization of coal mining face in the United Kingdom” at the ninth issue of “Happiness” magazine in West Germany. The article analyzes and studies the effect of face mechanization in the United Kingdom from 1960 to 1980 and puts forward a very worthwhile question: whether the higher degree of mechanization is better? During these two decades, the United Kingdom has paid a lot of money for coal mines, mainly For mechanized face, mechanized face production increased from 37.5% of total output to 94%. However, a large number of statistics show that these changes did not make the best profits from coal mines.
