中国的煤炭资源比较丰富,但是薄煤层资源却居多,很多都是1.3m以下煤层。在全国薄煤层可采储量约占整个可采储量的20%以上,总储量达到60亿t,该类资源分布较广,有些地区的煤质也比较好。多年来开采,不少矿井中的厚煤层已近枯竭,薄煤层的开采正规模化的进行,而且也得到了人们的充分重视。文章简要介绍中国薄煤层煤炭资源的储存情况、薄煤层开采机械的几种类型。薄煤层机械化开采较成熟的工艺主要有长壁式开采、螺旋钻机开采、连续采煤机房柱式开采、急倾斜煤层钢丝锯开采。
China is rich in coal resources, but thin coal seam resources are mostly, many of them are below 1.3m coal seam. In the country, the recoverable reserves of thin coal seam accounts for more than 20% of the total recoverable reserves and the total reserves reach 6 billion tons. Such resources are widely distributed and the quality of coal in some areas is relatively good. Many years of mining, many coal mines in the thick seam has been nearly depleted, thin seam mining is formally modeled, but also get people’s attention. The paper briefly introduces the storage of coal resources in thin coal seam in China and several types of thin seam mining machinery. The mechanized mining of thin coal seam more mature technology mainly longwall mining, auger mining, continuous coal mining machine room column mining, steep coal seam mining.
