Deep open pit walls design using rock mass stress-strained state

One of the main deep open pit mining problems is the wall stability for a long time. It is obvious that the basic area of stress concentration in deep pits is the lower  edges of pit  walls. We have been studying the possibility of reducing stress concentrations like these by means of the alteration of the open pit bottom part configuration. To do this, there was considered  the  shape with a smooth passage from walls to the bottom of the pit (by widening the berms in the lower part) instead of trapezoid shape. Calculations were carried out  for deep open pits with a flat and rounded bottom across and along the strike of the ore body.

Investigation of present-day stress-strain state of rock mass by the results of observations at geodynamic polygons

The methods are suggested for treatment of the results of optical distance and levelling measurements at the underground geodynamic polygons involving in their calculation the tensors of additional stresses and deformations, component of rotation and specific energy of deformability. As an example, consideration is given to changes in time of movements, deformations and specific energy of deformability at one of geodynamic polygons of the Kola peninsular.

Systematization of factors to be considered in mine abandonment design

Subsoil is not just a source of mineral resources; it also serves as a burial site of industrial and domestic wastes, a storage place for oil and gas, and an environment for constructing underground facilities and creating preservations and nature sanctuaries. Subsoil area development is intensified and diversified with each passing year, exerting great influence on ecological systems and all their components. Special attention should be paid to terrain as upper facet of lithosphere, submitted to maximal impact of anthropogenic processes. Activation and emergence of natural and anthropogenic processes causes changes manifested in various combinations of negative events. Most important events include deformations of rock mass and land surface: exhaustion and pollution of ground and surface water, waterflooding and swamping of tapped sites, soil dehydration and salinization, air pollution, land site withdrawal from commercial circulation etc.
