摘要
地压灾害对于地表及井下人员、设备都是极大的威胁,矿山通过建立地压监测系统来对地压灾害进行预测。在位移和应力监测中,由于监测数据的获取都是非等时距的,因此难以建立合理的预测模型。通过在高阳铁矿地压灾害预测中的运用表明,利用非等时距灰色预测模型进行地压灾害预测,预测值与监测值拟合较好,模型精度高,能为地压灾害的预测提供依据。
It＇s a huge threat of the ground-pressure disaster in the mine to the miners and equipments of the surface and underground.Generally,the mines forecast the ground-pressure disaster by building the monitoring system of ground-pressure.The data is unequal interval in the monitoring of general displacement and stress,so it＇s difficult to build the reasonable forecast model.The ground-pressure disaster forecasted by building the model of unequal interval grey model in Gaoyang iron mine proves that the forecasting data and the monitoring data by the model are closely fitted and the model is highly accurate.This model can provide a basis for the forecast of ground-pressure disaster.
