DEVELOPMENT OF FORECASTING METHODS FOR GEOMECHANICAL PROCESSES IN ROCK MASS ARRAYS

Abstract

Significant horizontal tectonic stresses with a zonal distribution of vectors that determine the geomechanical state
of the massifs during mining and construction works have
been established within the Tien Shan mountain system.
Timely and objective assessment of the geomechanical
state of the rock mass not only prevents the impact of negative geomechanical processes, but also generally determines the technical and economic indicators of mining
works and mountainous construction activities.
At the same time, the practice of designing, building and
operating mining enterprises and other construction objects in the republic shows a high level of manifestations
of negative geomechanical processes in rock massifs at
the stages of their construction and operation.
In order to study the geomechanical processes that took
place in the rock masses throughout the geological history
of the studied objects accumulated in the so-called "geological memory", to predict their possible manifestation
and control them, we offer a method of zonal and phased
forecasting of the geomechanical state of an array including: a method of geological assessment at the first stage
within the folded zone, a method of mining and geological
assessment within the field at the second stage and methods of mining and technological assessment and monitoring of the state of the rock mass near the mining area or
exposure in the dynamics of work at the third stage.
Application of the developed methods for assessing the geomechanical condition of rock masses of some: ore deposits – Tereksai, Khaidarkan, Trudovoye; coal deposits –
Kara-Keche, Min-Kush, Kok-Moinok, Tash-Komur, gave
positive results when choosing the location of the open pit
openings and dumps, the optimal parameters for stripping, mining, sinking and second works, design and planning of new sites.
In this article, the author reveals the essence of the method
of assessing the first stage – the stage of geological assessment of the rock massif of the folded zone of the field
location, which allows switching to the second and third
stages of the assessing methods, which contribute to the
creation of a geomechanical model of the object, which
will be highlighted in subsequent publications of the author.
