综采面支承压力及塑性区变化规律数值模拟研究

摘要

以白坪矿二，煤层为具体原始条件，利用三维数值模拟软件FLAC^3D，分析了随采高不同，综采工作面前方支承压力及煤壁塑性区分布特征和变化规律。%Using three-dimensional numerical simulation software FLAC^3D, the paper analyzed the variation of support pressure and plastic deformation zone in the different mining height in fully mechanized mining face.
