以黄沙矿2上采煤工作面为研究对象,分析了该工作面矿山压力显现的规律与特点;以三次指数平滑法为基础,结合最小二乘法原理,建立了改进三次指数平滑法,并运用该方法对黄沙矿2上采煤工作面矿山压力进行了预测研究。研究结果表明:该工作面矿山压力显现具有明显的非线性和非规律性特点,且周期来压特性不明显,建立的改进三次指数平滑法可以用来对矿山压力进行预测研究,且预测精度较高;该方法对矿山压力的非现性、非规律性适应能力较强。
Taking the 2up coal mining face in Huangsha Mine as the study object,the paper analyzed the mine strata pressure behavior law and features of the coal mining face.Base on the cubic exponential smooth method,in combination with the principle of the minimum square method,the improved cubic exponential smooth method was set up and was applied to the prediction study on the mine strata pressure of the 2up coal mining face in Huangsha Mine.The study results showed that the mine strata pressure behavior of the coal mining face would have the obvious features of the nonlinear and non-law and the periodical pressurized features would not be obvious.The improved cubic exponential smooth method established could be applied to the prediction study on the mine strata pressure and the prediction accuracy would be high.The improved cubic exponential smooth method would have a high suitability to the nonlinear and non-law of the mine strata pressure.
