摘　　要：为了研究综采面直接顶稳定性影响因素的影响程度,本文运用Fl AC^(3D)数值模拟软件建立了综采面稳定性模型,通过控制变量法得出端面直接顶板在不同液压支架支护阻力,不同端面距以及不同直接顶厚度条件下的顶板下沉量曲线,得出液压支架支护阻力、端面距和直接顶的厚度3个因素与端面直接顶稳定性的关系,为煤矿工作面安全生产提供理论依据。In order to ensure safe and efficient production of coal mine,the stability model of fully mechanized face was established by using FLAC3D numerical simulation software.The control variable method was used to obtain the direct roof subsidence values under the conditions of different hydraulic support resistance,different end-face distance and different direct roof thickness,furthermore the relationships between the stability of the direct roof and its influence factors were drawn out such as support resistance,end-face distance and direct roof thickness,providing a theoretical basis for the safe production of coal face.

关 键 词：支护阻力 端面距 直接顶厚度 数值模拟
