| 摘 要： | 对某矿回采动压巷道梯形金属支架的收敛量测值进行分析，反求出支架上的压力，初步掌握了该矿回采动压巷道的压力变化规律，认识到，此类巷道用锚、带、喷联合支护较适宜。为了检验锚、带、喷联合支护的安全、可靠性，在采用此支护形式的运输顺槽内进行了长期的巷道收敛监测，并利用时序分析中的门限自回归模型对所测的八组收敛观测序列值进行拟合，对本巷道的未来收敛情况进行预报。

| Abstract: | The convergence values of trapezoidal steel supports observed in extraction galleries of a coalmine are analyzed,the pressure distribution on the supports is reversely calculated,and the changing law of the pressure is preliminarily obtained.Then we realized that it is suitable for such kind of gelleries to use the combined supports with bolting strip and shotcrete. In order to test the safety and reliability of the new type of supports,the roof convergence in headgates with such kind of supports was observed for long time. By using the threshold and autoregressing model of time series analysis,eight groups of observed se-ries values are fitted to forecast the future convergence values of the headgate. |
