英文摘要In this article, based on the prototype of the metal mine, by applying the geological mechanics modeling test, We deeply analyzed the surface's deformation and subsidence varying rules versus excavating steps, the varying rules for the range of surface's deformation and subsidence following with mining levels and the varying rules of surface's deformation and subsidence versus time with the thick covering terrane. This test realistically simulates not only the complex geological condition of the selected sections but also the excavating process of natural mining. The surface's subsidence and deformation are little when we have mined from -270m to -550m, But its increase rapidly after mining to -200m. The creeping graph of the measuring points takes on the character like the pattern described by epsilon(t) = epsilon(0) + k(1)e(k3/3 root t) On the condition of the present mining level, the creeping graphs all tends to be convergent. The surface displacement tends to be stable in about 46 to 50 days after the finishing of the excavating. According to the results of the experiment, the optimum initial-mining altitude was adopted by the mining company.
