Conclusions
-
1.
Investigations of the acoustic and strength properties of Karaganda sandstones have enabled the authors to derive empirical equations for the interrelationship of these parameters.
-
2.
The experimental data justify the recommendation of the ultrasonic pulse method for assessing the strengths of sandstones, because it is less laborious and enables investigations to be performed on the rock mass in situ.
