摘要
文中为研究沙土层覆盖下的厚煤层综放开采地表移动规律,在敏东一矿01工作面上方建立了地表移动观测站进行观测,通过对该工作面开采期间的地表移动观测数据分析,得出了在内蒙东部草原地区沙土层覆盖条件下厚煤层开采地表移动的特征及预计参数。
In this paper,in order to study the law of surface movement of fully mechanized top coal caving mining in thick coal seam covered with sandy soil,the surface movement observation station was set up above working face 01 in Mindong No. 1 Coal Mine,based on the observation data of surface movement during the mining period of the working face,the characteristics and the predicted parameters of surface movement in thick coal seam mining under the condition of sandy soil cover were obtained in the grassland area of east of Inner Mongolia.
