Abstract
The paper presents the estimation of the engineering-geological conditions of the surface mining in Ainskoe gold field. The mechanical-and-physical properties of the rock are described in this paper, and the stability calculations are provided for the pit walls. Recommendations are given for the geoecological safety measures during the surface mining.
Highlights
The exploration of mineral deposits using the surface mining poses a lot of problems related to the geodynamical disbalance of the environment, contamination of the atmosphere, surface and ground waters
A predictive estimate of the engineering-geological conditions is very important for the surface mining and the stability of pit walls
Since the Ainskoe gold field is located in seismic area with the earthquake intensity of 9, the pit wall analysis is carried out accounting for seismic forces
Summary
The exploration of mineral deposits using the surface mining poses a lot of problems related to the geodynamical disbalance of the environment, contamination of the atmosphere, surface and ground waters. The surface mining has an effect on the geological environment resulting in the modification of the stress-strain state of subsurface rocks, instability of pit walls and the development of geological hazards. In this connection, a predictive estimate of the engineering-geological conditions is very important for the surface mining and the stability of pit walls. Its natural and climatic factors affecting the surface mining include the climate, geological structure, composition and mechanicaland-physical properties of rocks
