厚松散层条件下煤层开采地表沉陷,有其自身的特点和规律。文章分析了厚松散层在综放开采条件下地表移动参数的特点,得出了地表移动参数与地质、采矿因素之间的关系,为研究厚松散层下煤层开采地表移动规律提供理论依据。
Under the condition of loose and loose layer, the surface subsidence of coal seam mining has its own characteristics and laws. The paper analyzes the characteristics of the surface movement parameters of the thick loose layer under the conditions of fully mechanized top - coal caving mining. The relationship between the surface movement parameters and the geology and mining factors is obtained, which provides a theoretical basis for studying the surface movement rule of the coal seam under the thick alluvium.
