摘　　要：针对14218工作面矿压显现现象,采用理论分析与现场观测,分析了工作面在不同覆岩形态下的矿压显现机理;分析了支护系统中,支架"抬头""低头"工作形态对直接顶变形失稳的影响;得出了工作面在煤柱下方、煤柱采空区毗连区、采空区下方矿压显现特点,针对不同的矿压显现采取措施,并在实际中取得了较好的效果。According to the phenomenon of underground pressure appearance in 14218 working face,the mechanism of underground pressure appearance in different overburden forms is analyzed by theoretical analysis and field observation. In the support system, the influence of the working forms of "up" and "down" of support on the deformation and instability of direct roof is analyzed. The characteristics of ground pressure appearance in the working face under the coal pillar, adjacent area of coal pillar and under the goaf are obtained point, according to different mine pressure appearance, measures are taken,and good results are achieved in practice.
