Abstract: Analysing for correlation of coal rock physico-mechanical parameters and three lateral resistivity logging parameters in LuoYuan mine field. The results show that the correlation of three lateral resistivity logging parameters and rock physical parameters is low, but the correlation of three lateral resistivity logging parameters and rock mechanics parameters is significant. Linear regression analysis was carried out on parameter of high correlation, and select the regression equation with higher significantly and small residual error as a prediction model of rock mechanics parameters.Applying the model to quantitative prediction of rock mechanics parameters in During inspection hole. By contrast with predictive values and measured values, it is proved that the prediction model has a strong practicability.
