一、前言 本文根据最近召开的“欧洲经济共同体采煤新技术与新方法” 会议宣读的一些论文,摘选了复杂地质条件下采煤技术的有关资料。 长壁开采法在煤矿生产中占绝对优势,将近66％的煤是采用长壁开采法生产的。西德、捷克斯洛伐克和日本等国,几乎所有的煤都是采用长壁开采法生产的。 长壁采煤法比房柱式采煤法适应的地质条件范围广,特别是对于顶板极度破碎的急倾斜煤层来说,采用长壁开采法最有利。
I. Preface According to some papers read in the recently held “New Technologies and New Methods of Coal Mining in European Economic Community”, this paper extracts the relevant information of coal mining technology under complicated geological conditions. Longwall mining method is an absolute advantage in coal mine production, and nearly 66% of the coal is produced by longwall mining method. Nearly all of the coal in West Germany, Czechoslovakia and Japan is produced using longwall mining methods. The longwall mining method is more suitable than the post mining method to adapt to a wide range of geological conditions, especially for the roof crushed steep seam, the use of longwall mining method is the most favorable.
