摘　　要：依据某矿94204工作面具体地质参数,结合工作面来压时顶板上覆岩层的活动规律,提出了实时进行矿压监测可以有效地预防煤矿企业发生顶板事故的几率。监测结果表明:94204工作面来压时,仅在采空区悬顶、煤壁片帮处来压强度较大,伴随工作面的不断推进,顶板来压强度逐渐减弱,来压步距呈现周期性变化,工作面通过加强支护管理,支护经济效果显著。According to mine 94204 face specific geological parameters, combined with the pressure of working face to the law of roof overburden activity, puts forward the mine pressure with the real-time monitoring can effectively prevent the risk of roof accidents of coal mining enterprises. Monitoring results show that the 94204 face to pressure, only in gob roof hanging, coal wall help to compressive strength is larger, along with the working face advancing, the roof weighting intensity gradually weakened, weighting interval periodic changes, timely by strengthening support management, supporting the economic effect is remarkable.
