Research of the internal structure of diabase samples by optical-acoustic and computer x-ray tomography

Popis výsledku v původním jazyce

The paper examines the internal structure of overburden diabase specimens from the Pavlovskoye ore deposit. Petrographic and elemental analyzes were performed using a scanning electron microscope. The physical and mechanical parameters of the specimens were evaluated, including the ultimate uniaxial compressive strength, the ultimate tension strength, the modulus of elasticity, and Poisson’s ratio. We determined the geometry of internal defects, such as cracks about 200—300 microns long, related to decompaction between grains. It is shown that the dynamic elastic moduli can tbe determined from precise elastic wave velocity measurements.
