| Abstract: | Analysing for correlation between coal rock acoustic logging curve amplitude and static mechanical parameters, extracting the parameters of more significant correlation,and establishing the statistical relation model. Applying the model to quantitative prediction of coal rock mechanics parameters.By contrast with predictive values and measured values, it is proved that prediction accuracy of the prediction model can satisfy the requirement of practical production. |
