Hello,

perhaps you can use the spectral reflectance of the minerals as an indirect assessment of the rock strength. But this makes only sense if you are aware of the nature of the rock regarding the type of rock (magmatic, sedimentary, metamorphic), fissures, layering, cracks, joints, burial history, degree of diagnesis and so on. The results from spectral measurements alone won't give a valuable information on the strength of a rock.
