... by including rock strength and the quartz plus feldspar content to the analysis. The correlation coefficient of the multiple regression model is slightly higher than that of the simple regression model. Concluding remark is that the evaluation of the abrasivity characteristics of igneous rocks should...

... developed Specific Rock Mass Drillability (SRMD) index. Multiple linear regression analyses were used to develop a new equation for predicting the penetration rate of rotary drills. Comparison of measured SRMD with those predicted by multi-linear regression model showed good agreement with correlation...
