Abstract

Work aim is to carry out geomonitoring of rock mass state, which provides for comprehensive accounting and analysis of all natural and man-made factors, as well as use of methods and control tools developed by authors.Work uses complex method, including: study of mining and geological conditions, structural features of rocks of deposits and conduct of mine surveying observations in mines based on innovative methods and means of geomonitoring developed by the authors. Research materials of geomechanical processes at the mines of Akzhal, Saryoba Sayak and others are presented during projects implementation of «Development of innovative methods for predicting and assessment of rock mass state to prevent technogenic emergencies» and «Comprehensive monitoring of slow deformation processes of the earth's surface during large-scale development of ore deposits of Central Kazakhstan», and also used in the educational process of Satbayev University. As a result of research: methodology for comprehensive assessment of rocks state has been developed, which makes it possible to consider features of geological structure of undermined strata and, thereby, improve quality of geomechanical support for mining operations; design of permanent forced centering point (FCP) for installation of high-precision instruments has been developed, which makes it possible to ensure speed and accuracy of centering, as well as to exclude use of tripods; scientifically substantiated possibility of predicting stress-strain state of rock mass in the studied deposits, i.e. it is possible to determine: tensile strength - σco; clutch - K; density - γ and strength of rocks - f according to the scale of M.M. Protodyakonov; composition of hardening solution from mining waste has been developed to increase stability of sections of ledges of quarry, which has high fluidity, adhesion to rocks and sufficient strength.
