应用距离判别法预测煤矿冲击地压危险性

Prediction of Rock Burst Risk in Coal Mine by Distance Discriminant Method

以某矿区为实例,确定了影响该矿区冲击地压的主要地质及开采技术因素,应用距离判别法建立了距离判别预测模型,并利用统计软件对该矿区的冲击地压实测数据进行模型预测,预测效果非常明显。结果表明,建立的距离判别分析模型用于预测冲击地压强度是可行的,可以在实际工程中进行推广应用。

Take a coalmine as example,its main geology and mining factors of effecting the risk of rockburst were determined.The forecasting model was established by using the distance discriminant method,and the testing data was input into the model to predict the rockburst.The results show that this forecasting model based on distance discriminant method can predict the risk of rockburst effectively,and can be applied to the prediction of rockburst in the mining area.
