湖南隆回县大园煤矿位于箍脚底煤田复向斜的东南翼,第三水平又位于复向斜的轴部,构造复杂,地层受到严重挤压,积聚着较大的构造应力.该井田共含三层煤,Ⅰ煤不可采,Ⅱ煤局部可采,主采煤为Ⅲ煤.Ⅲ煤厚0.5～1.8米,平均厚度为1米,其品种为无烟煤,透气性低,顶板为较厚的炭质泥岩、砂质泥岩,突出较为严重.1968～1985年共发生突出580次,突出煤矸总量为35700吨, The Dayuan coal mine in Longhui County, Hunan Province is located in the southeast wing of the synclinorium of the foot coal bed and the third level is located in the axis of the syncline. The structure is complicated and the formation is severely squeezed and a large tectonic stress is accumulated. With three layers of coal, Ⅰ coal can not be taken, Ⅱ coal locally recoverable, the main coal for the Ⅲ coal. Ⅲ coal thickness of 0.5 to 1.8 meters, an average thickness of 1 m, the varieties of anthracite, low permeability, roof is thick Of the carbonaceous mudstone, sandy mudstone, prominence is more serious.From 1968 to 1985 a total of 580 times outstanding, highlighting the total amount of coal gangue 35700 tons,
