A mineral-strength conversion model based on LIBS technology and rapid batch testing and application of uniaxial compressive strength by Qinghe ZHANG, Xiaorui WANG, Chuanbing WANG, Weiguo LI, Fengqiang GONG, Xinsheng ZHANG, Jingguo LI

“…Results indicate that the coefficient of determination R2 of each element in the spectral-elemental prediction model is between 0.96 and 0.99, and the model can effectively obtain the content of each element; the elemental-mineral prediction model has the best prediction effect of quartz and aluminum phosphate, followed by feldspathic and mica mineral groups, and good prediction effect of chlorite and turbidite zeolite as well. The multiple linear regression model (R2 = 0.850 2) is more suitable than the least squares method (R2 = 0.719 6) for the nonlinear relationship between the predicted value of mineral mass fraction and uniaxial compressive strength, and the introduction of the correction coefficients can be more effective in realizing the accurate conversion of minerals-strengths. …”
