基于物探磁法的矿山地质灾害预测研究

Research on mine geological disaster prediction based on geophysical magnetic method

由于传统的矿山地质灾害预测方法存在预测峰值低的问题,为此进行基于物探磁法的矿山地质灾害预测研。首先,通过物探磁法划分矿山地质灾害易发分区单元网格,将地磁场变化特征以矩形阵势进行排列;再通过计算矿山地质灾害预测映射误差,剔除计算得出的映射误差;最后,构建矿山地质灾害预测方程式,完成矿山地质灾害预测。设计实例分析,结果表明,设计的预测方法预测峰值最高可达180.52gal,实验对照组最高仅为121.45 gal,设计的预测方法峰值更高,可以实现对矿山地质灾害的精准预测。

Due to the low peak value of the traditional mine geological disaster prediction method,the mine geological disaster prediction research based on geophysical magnetic method is carried out.Firstly,the unit grid is divided by geophysical magnetic method,and the variation characteristics of geomagnetic field are arranged in rectangular array;then,the mapping error is eliminated by calculating the mapping error;finally,the prediction equation of mine geological disaster is constructed to complete the prediction of mine geological disaster.The results show that the peak value of the designed prediction method can reach 180.52 gal,while the experimental control group is only 121.45 Gal.the peak value of the designed prediction method is higher,which can realize the accurate prediction of mine geological disasters.
