Abstract
The development of mineral deposits has strong transformative effect on the geological environment. At the same time, all the components of geotechnical conditions (relief, structure of rock massifs, hydrogeological and geocryological conditions etc.), formed over a long geological time, are actively changing. Geological processes are activated and new mining-geological processes are formed. New strata are formed on the Earth's surface along with the technogenic formations and technogenic deposits. Today, the scale of technogenesis in mining is comparable to the results of geological activities that have been going on for many millions of years. The reaction of the geological environment is immediate and is expressed in the development of large-scale engineering and geological processes, which often do not allow the further development of mineral resources and threaten the human life. Therefore, even at the early stages of prospecting and/or exploration, it is necessary to understand the dynamics of changes in surrounding medium in order to develop methods for proper managing of the ore extraction. By the example of a number of objects, all the stages of study of engineering-geological conditions are considered, the dynamics of their change, which led to the formation of engineering-geological processes affecting the further development of mineral resource, is estimated.
Highlights
Geotechnical conditions (EGC) are an integral system of interrelated components that determine the complexity of the field development, the nature and scale of changes in the geological environment under the influence of mining processes (Abaturova, 2017; Gang etc., 2013).The active influence of mining into the upper layers of the earth's crust disrupts the natural balance that has developed over millions of years
The study of the engineering-geological conditions formed in the geological time at the deposits should be carried out in stages corresponding to the regulations for the study of mineral deposits
During opening and exploiting mineral resources, the impact on the geological environment is manifested in the form (Fig. 1):
Summary
Geotechnical (engineering-geological) conditions (EGC) are an integral system of interrelated components that determine the complexity of the field development, the nature and scale of changes in the geological environment under the influence of mining processes (Abaturova, 2017; Gang etc., 2013). The active influence of mining into the upper layers of the earth's crust disrupts the natural balance that has developed over millions of years. A number of changes, both of the geological nature (activation of exogenous geological processes) and technogenic (development of engineering and geological processes) arise that, in turn, complicate the technology of mining, threaten human life and health, and harm the environment (RadwanekBąk etc., 2020)
