| Abstract: | The Haigang section of 301 provincial highway in Gansu Province overlaps Yaojie Coal Resources deep expansion area.This paper constructs a calculation model to determine the evaluation range of the overlaps.By comparing the situation of other mining areas and combining with the geological conditions of Yaojie coal resources deep expansion area,the bedrock movement angle is determined.The upward movement angle γ and coal seam strike movement angle δ are 68 °.The relationship between the uphill movement angle γ,downhill movement angle β and coal seam dip angle is β=δ-0.7α,and the evaluation range of overburden is determined by calculation model. |
