The overall complexity of studying the discipline is 4.5 credits (162 hours)

The purpose of discipline. Formation of theoretical knowledge and practical skills to determine the physical and mechanical properties of mining breed stresses arising in the array, which affect the stability of mining.

Problems of discipline.

- determination of physical and mechanical properties of rocks by laboratory and production testing of samples of these rocks;

- evaluate the stress state of the rock mass by identifying tensions in the sides of pits and dump slopes;

- set of strength parameters of rock by the results of theoretical studies undisturbed by surveying the array shifted shooting rocks in the quarry;

- to analyze the stability of the rock mass on ledges in the dumps around the underground workings based on loads of equipment, construction of supporting prisms and walls, the influence of water, the presence of layers of plastic rocks laxatives and other factors;

- identify possible array type strain and violations stability at slop structures using hydrogeological and engineering-geological documentation;

- calculate the parameters of gravitational movement and releasing rock underground, open shafts and bunkers;

- generate students' research skills, experience with textbooks, manuals, scientific books, periodicals, and other sources of information;

- encourage students to systematic self-study work.
