一、概况新邱立井是1958年投产的。该井煤田地层属侏罗纪,煤层呈单斜构造,赋存不稳定。多属走向断层。倾角为10～30°。主要可采煤层有中层群、下层群,共13个煤层。见图1。水平分区石门开拓方式。采煤方法是走向长壁。通风方式为中央抽出式通风,配备两台 B—Y_1Д二段轴流扇风机。原设计第一水平为三级瓦斯矿井,投产后实际鉴定为超级。历年来,相对瓦斯涌出 First, an overview of the new Qiu Lijing was put into operation in 1958. The well coalfield strata belong to Jurassic, the coal seam is monoclinic with unstable occurrence. Mostly to the fault. Inclination is 10 ~ 30 °. The main recoverable coal seam has a middle group, the lower group, a total of 13 coal seams. see picture 1. Horizontal partition Shimen pioneering ways. Coal mining method is to the long wall. Ventilation for the central out of ventilation, equipped with two B-Y_1Д two axial fans. The original design of the first level of three gas mines, put into operation after the actual identification as super. Over the years, the relative gas emission
