Physical and Mechanical Properties of Ore and Rocks after Flooding
Abstract
The authors investigate the physical and mechanical properties of hornstone, gabbro-dolerite and rich chalcopyrite–pyrrhotine ore subjected to flooding at the Oktyabrsky deposit in the Talnakh ore province. The analysis of the petrography, chemistry and mineralogy of the test samples showed no substantial differences in their properties after flooding. The comparison of the strength and deformation characteristics of rocks from the uniaxial compression and tension testing results demonstrate the decrease of both in water-saturated rocks and the increase in the room-temperature dried samples. The limit strength, elasticity modulus and internal friction angles have smaller values in rocks after drying than in the initial samples.
