Abstract: To study the mountainous terrain of the expected impact of mining subsidence, according to the particularity of loess mountainous terrain, the unit volume deformation of slope under the condition is decomposed into incremental deformation normal underground volume deformation and the plastic slip caused by volume, and then use the relevant expected Additional models will affect the hillside slippage results with conventional mining subsidence superimposed, mountainous terrain as mining subsidence expected results. Through research and analysis, the impact of loess slope slip mountainous terrain conducted in-depth discussion of the theory. And conducted face Tongchuan Mine Y905 as an example to validate the theoretical analysis results match the actual measurement data, confirmed the hillside slippage in considering the impact deformation of surface subsidence, with its superimposed manner expected, more suitable for the western loess mountains mining subsidence prediction.
