Study on surface movement rules of mining inclined coal seam under thick loose strata

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.
