摘　　要：区域地层情况、构造情况以及沉积环境对于矿井工程的实施具有决定性作用。为研究沉积环境及构造情况对煤层开采的影响,以西南某勘察区为研究对象,分析了区域内地层、构造、沉积环境以及古地质情况对煤层的影响,得到以下结论:①区域内含煤地层分为4层,主要构造为2个大型构造;②煤系为海陆交互相沉积,沉积物堆积区是靠海的湖沼与盆地地带;③勘查区在地质作用下,煤呈灰黑-黑色,煤层水分北低南高,煤层厚度呈现中部高、南北两边逐渐变薄的现象。Regional stratigraphic conditions,structural conditions and depositional environment play a decisive role in the implementation of mine engineering.In order to study the influence of sedimentary environment and structure on coal seam mining,a survey area in southwest China was taken as the research object,and the influence of strata,structure,sedimentary environment and paleo geological conditions on coal seam in the area was analyzed,and the following conclusions were obtained:①The coal-bearing strata in the area are:There are 4 bottom layers,and the main structure is 2 large-scale structures;②The coal measure is the sedimentary of sea-land interaction facies.Sediment accumulation areas are lakes and basins near the sea;③Under the geological action of the exploration area,the coal is gray-black to black,and the coal seam moisture is lower in the north and higher in the south;the thickness of the coal seam is higher in the middle,and gradually becomes thinner on the north and south sides.
