EXPRESS-TECHNIQUE OF GEOTECHNICAL SUPPORT OF MEASURES ON ENGINEERING PROTECTION IN ROCK MASSIVES
Currently, one of the main engineering and technical ways to solve the problem associated with the safety of open-pit mining at the existing risk of dangerous geological processes is the introduction of various engineering protection technologies. As practice shows, the unprofessional level of design decisions often leads to premature failure, and sometimes complete destruction of structures of protective structures with all the ensuing economic consequences. The implementation of a set of measures, which ensures a sufficient volume and completeness of the research, strict accordance and observation with design solutions, the requirements of current standards and regulations (including observation with qualification requirements), the proper level of supervision, maintenance at all stages of construction could guarantee a quality of emergency response. Visual methods of control widely used for geotechnical monitoring of protective structures for objective reasons do not provide highly reliable qualitative and quantitative information about the real state of the “engineering protection - rock mass” geosystem and forecast its changing over time. In solving this task, only the integrated use of information technologies and data of instrumental geomonitoring contributes to the correct (and in some cases, operational) technical decision-making with ensuring the high quality of their implementation. The express-techniques of geotechnical support of engineering protection measures in rock massifs presented in this article, which consists in the comprehensive use of modern interdisciplinary geomonitoring methods, computer modeling and feasibility studies, is aimed at improving the efficiency and reliability of design decisions made on the basis of low-budget studies.
