一、国外薄煤层开采机械化简况纵观国外主要产煤国家薄煤层开采技术动向,总的趋势是重视对薄煤层开采机械化的研究工作,效果显著,基本解决了薄煤层普采和综采的技术问题。现以苏联、西德、英国、美国、法国、波兰等国为例作以下简述。 First, the foreign thin seam mining mechanization brief overview of the main coal-producing countries in the thin seam mining technology trends, the general trend is to pay attention to the thin seam mining mechanization research work, the effect is significant, basically solved the thin seam coal mining and fully mechanized mining technology problem. Now the Soviet Union, West Germany, Britain, the United States, France, Poland and other countries as an example for the following brief.
