Experiment Research of Luming Molybdenum Mine Rock Physical and Mechanical Properties

Physical and mechanical properties of rocks are the fundamental factors affecting the slope stability, the rock physical and mechanical properties of the Luming molybdenum mine were tested and analyzed in the laboratory. The results can provide us the basic data and reference to do numerical simulation and physical simulation of slope stability. The experimental results showed that: the greater the depth of rock of Luming molybdenum mine, the greater the density becomes,so as the freeze-thaw coefficient; the rock strength complies with the general rule; uniaxial tensile strength of dried rocks is much larger than water-saturated rocks; various rocks compressive strength σ3 rose up with σ1 rising; the shear strength of the rocks containing weak structure surface is far less than the shear strength of the intact rocks.
