EXPRESS-TECHNIQUE OF GEOTECHNICAL SUPPORT OF MEASURES ON ENGINEERING PROTECTION IN ROCK MASSIVES

Abstract

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.
