基于多元线性回归的底板破坏深度研究

Floor failure depth study of multiple linear regression to predict in Jiaozuo Mining Area

针对焦作煤田大采深、高承压、底板相对隔水层较薄的特点,利用多元线性回归的方法对底板破坏深度进行预测,对高承压高应力破碎底板突水机理进行研究。并采用钻孔分段注水观测、钻孔成像的方法对底板破坏深度进行实测。预测数据与实测数据对比表明,基于多元线性回归的方法所得出的预测结果非常接近现场实测结果,预测方法可以为焦作煤田的底板突水预测预报研究提供可靠的参考依据。

Jiaozuo coal mining depth for large, high-pressure, relatively impermeable layer of thin plate characteristics, the use of multiple linear regression method to predict the depth of damage on the floor, on the floor in high stress broken high pressure water inrush mechanism research. And the use of sub-injection observation drilling, drilling imaging method for depth measurement floor damage. Forecast data and measured data show that the prediction was based on the results of multiple linear regression results are very close to the measured results, the method can predict sudden water to bottom of Jiaozuo Coal Research estimates provide a reliable forecast of reference.
