山西省霍县矿务局辛置煤矿南区副暗斜井上部车场,担负着南区的进风、排矸、上下人员、下放材料和设备等任务,设计为较大的半圆拱形断面(见图1),其净断面面积为31.1米~2,掘进断面积为42.2米~2。该车场大巷全长45米,岩层为f=4的砂质泥岩、页岩和砂岩,稳定性较差,所以确定采用双导峒法施工,永久支护为料石砌璇。
Huoxian Mining Bureau of Shanxi Province, Xinzhi coal mine in the south of the area under the dark incline well, responsible for the South District into the wind, gangue, up and down personnel, decentralized materials and equipment and other tasks designed for larger semi-circular arched section See Figure 1), the net cross-sectional area of 31.1 m ~ 2, tunneling area of 42.2 m ~ 2. The yard is 45 meters in length. The rock formations are sandy mudstone, shale and sandstone with f = 4. The stability is poor. Therefore, it is determined that the construction should be based on double guide method and the permanent support should be made of stone.
