我井设计能力年产21万吨,一对斜井开拓,中央边界式通风。现采水平走向长度2.5公里,倾斜长度1公里。可采煤层为高炭一层,其厚为0.45—0.6米。直接顶厚0.3—1.2米左右,属泥岩或粉砂岩。煤层倾角为6—11°。矿井属高瓦斯矿井。区内小断层多,古河流冲刷频繁,造成大面积的煤层缺失或变薄。 1957年投产以来,采用上山盘区巷道布置,采区前进,区内后退,走向长壁式开采。1978年以来。为了适应采煤机械化的发 I well design ability with an annual output of 210,000 tons, a pair of inclined shaft to open up, the central boundary-style ventilation. The mining level is 2.5 km in length and 1 km in length. Coal seam can be a high carbon layer, the thickness of 0.45-0.6 meters. Direct top thickness of 0.3-1.2 meters, is a mudstone or siltstone. Seam angle is 6-11 °. Mine is a high gas mine. Small faults in the area, the ancient river erosion frequently, resulting in a large area of ​​the coal missing or thinning. Since its commissioning in 1957, it has adopted the layout of the roadway in the uphill area to move the mining area forward and the area to retreat toward long-wall mining. Since 1978. In order to adapt to the coal mechanized hair
