ENSURING SAFE MINING OPERATIONS IN THE DEVELOPMENT OF SOKOLOVSKOYE IRON ORE DEPOSIT

Abstract

Intensification of natural environment development is the main reason for the growth in the number of technonatural disasters. The number of injured and died in the mining industry is higher than in other industries in Russia and Kazakhstan.
Complex hydrogeological conditions of the rock mass of Sokolovskoye deposit determine the need for constant search for new solutions to improve industrial safety. The presence of undrained hydrogeological horizons and complexes, karst, the presence of thixotropic rocks in the section create conditions for the accumulation and breakthrough of water and mud masses into the mine. The overwhelming number of breakthroughs of sand-clay deposits is accounted for the main mining horizons in
production and delivery. For a complete understanding for the mechanism of formation and implementation of hazardous phenomena, it is necessary to study the geological environment in order to prevent catastrophic events, improve measures and means to ensure the safety of personnel. At present, there is a significant amount of information about the engineering and geological conditions of the deposit's rock mass, on the basis of which the measures have been developed to ensure industrial
safety and technological solutions for mining. The current stage of the development of the deposit has made it necessary to study in detail the specific hydro-geological and geomechanical conditions in order to improve the efficiency of drainage operations in local areas of the rock mass to be planned for the organization of ore mining.
