摘要: 文中基于现场实测资料,开展了厚松散层下倾斜煤层开采地表移动的观测与研究,获得了地表移动的角值参数、动态参数和预计参数,揭示了特定地质采矿条件下地表移动变形的一般规律和特点,为"三下"压煤开采和开采沉陷预计提供了技术依据。Abstract: Based on field measured data, the observation and study on surface movement of inclined coal seam mining under thick loose strata were carried out. T he angular parameters, the dynamic parameters and the predicted parameters of surface movement were obtained, and the general rules and characteristics of surface movement and deformation were revealed. It provided a technical basis for the coal mining and surface movement prediction under the buildings,water bodies and railw ays.
