摘　　要：利用FLAC 3D数值模拟软件,综合考虑深埋煤层综放开采条件下采高和埋深对垮落带高度的影响,计算得出采高和埋深的单因素和双因素回归分析方程。通过对比分析,回归方程比传统经验公式更加适用,且回归方程所得结果与实际垮落带高度十分接近,对深部综放工作面的安全生产有着一定实际应用价值。By using numerical simulation software FLAC 3D and considering overall the influence of mining height and buried depth on the height of caving zone in the conditions of full-mechanized caving mining in deep seam, the single-factor and double- factor regression analysis equations were calculated. The contrastive analysis results showed that the regression equations were more applicable than the traditional experience formula, and the height of caving zone calculated by the regression formulas were closer to the field measurement, which had a certain practical application value to safety production of deep fully mechanized caving face.
