Gravitational and tectonic stresses in the rock mass and their determination by measurements in separate points
(National Mining University, 2017-09-30)
Purpose. Stress state in rock mass is the most important factor affecting processes around mine working. The methods used for calculation of stresses based on hypotheses of elastic thrust, hydrostatic state or spherical ...
