FIELD: mining industry.
SUBSTANCE: method includes mounting a sample between panels of capacitor converter of electromagnetic radiation, deforming thereof in loading device. Loading device has oppositely mounted in metallic body of loading device metallic rods, force detector and registration system. Compressing external force is applied to sample from first metallic rod through force detector body and it is destroyed due to reaction force of conic indenter of second metallic rod. Metallic body of loading device is a first plate of capacitor converter, second plate - second metallic rod, mounted in bushing of dielectric material, placed in metallic body. Stand has screen, frame, capacitor converter, loading device, force detector and registration system. Between ends of metallic rods force detector and sample are positioned. Second metallic rod is provided with conic indenter.
EFFECT: higher efficiency.
