摘要
Abstract
The characteristics of overlying strata destruction and surface movement caused by coal seam mining by similar material and numerical simulation experiment methods are simulated and analyzed.Through the results contrast of underground mining,the study also summarized the stability conditions and development rules of loess landslide of coal measure strata in different occurrence conditions.Taking the same 30° dip angle of coal seam,the results show that the loess landslide is in the state of critical instability when working face advances to 100 meters and the landslide has the same inclination with the coal strata,whereas,as the coal strata and the landslide have the adverse inclination,the loess landslide is in the state of critical instability when the working face advances to 120 meters.It turns out that the status of the same inclination between coal measure strata and landslide is easier to induce the loess landslide than the status of the adverse inclination.关键词
