摘　　要：围岩压力的变化是导致煤矿巷道变形速度加快、使用寿命减少、甚至出现冒顶事故的重要因素。对煤矿巷道围岩压力进行结构安全性分析和预测,是保证煤矿安全生产的重要手段之一。结合朱仙庄煤矿工程,以围岩压力监测系统对围岩的实际监测为依据,运用一元非线性回归的方法,比较指数函数、对数函数和双曲线函数三种模型的线性相关系数与残差平方和,选取最优的非线性回归分析模型对所测围岩压力数据进行分析。通过所得拟合曲线判断煤矿巷道围岩压力的变化情况,并根据其图形的变化趋势预测将来一段时间的围岩的压力大小和稳定性,为煤矿巷道的动态施工提供一定的依据。The change of the rock pressure is a significant factor leading to coal mine roadway speedy deformation,reduction of available life and even roof collapse accident.Analyzing and predicting the structural safety of the rock pressure in coal mine roadway are both the important means to ensure the production stay safety in coal mine.Combined Zhu Xianzhuang coal mine project,according to the actual monitoring value acquired by rock pressure monitoring system of the surrounding rock,using the method of nonlinear regression analysis,the linear correlation coefficient and residual sum of squares of three models about exponential function,logarithmic function and hyperbolic function are compared,the optimal nonlinear regression analysis model is chosen to analyze the measured data of rock pressure.By the fitted curve to judge the change of rock pressure in coal mine roadway,according to the change of its graphic trend prediction of the future for a period of time the size of the rock pressure and stability,it provides a certain basis for the dynamic of coal mine roadway construction.
