摘　　要：为了研究煤矿首采工作面顶板岩层的运移规律,有效保证冲击地压和煤与瓦斯突出高危工作面的安全开采,综合运用理论计算、监测预测和数值模拟3种方法对某矿11041首采工作面岩层垮落步距进行预测研究。研究与分析结果表明,3种方法所得出顶板岩层运移规律与垮落步距具有较好的一致性。There were three methods： theoretical calculation, forecasting of monitoring and numerical simulation were applied to study the 11041 first working face＇s roof strata caving pace and research the rock movement regularity to effectively ensure the security of working face which exists rock burst and gas outburst dangerous. The results showed that the roof strata movement regularity gotten by three methods was consistent with roof strata caving pace.
