提起采煤,矿工们不需考虑即可脱口说出打眼放炮,扶棚钉道,开机割煤。但对于开采方法那就未必都知道了。其实采煤技术也象其他科学技术一样,风风雨雨几经周折。世界上经过几百年摸索和发展,到目前已形成了两大采煤体系:一是以前苏联、法国、波兰、中国为代表的长壁式采煤法;二是以美国、澳大利亚为主的房柱式和短壁式开采方法。所谓长壁式采煤就是把煤层划分成100～300米宽、1000～2000米长的区段,开出断面巷道,一边作为进回风,一边作为运输。这种方法采煤,只用少数掘进巷道就可以投入生产。长壁式开采有两种:一种是前 Mention of coal mining, miners who need to blurt out their mouths to speak out, the canopy Dingdao Road, cut the coal boot. But not necessarily for mining methods that know. In fact, coal mining technology, like other science and technology, ups and downs after several twists and turns. After several hundred years of exploration and development in the world, two major coal mining systems have been formed so far: one is the long-wall coal mining law previously represented by the Soviet Union, France, Poland and China; the second is the coal mining by the United States and Australia Column and short-wall mining methods. The so-called longwall coal mining is the coal seam is divided into 100 to 300 meters wide, 1000 to 2000 meters long section, out of the section of roadway, while as the return air, while as transport. This method of coal mining, only a few tunneling can be put into production. There are two types of longwall mining: one is before
