Abstract

The importance of the impact of emerging ecologic-geomorphological situations in areas of active mining development of Kazakhstan on the life of the population is difficult to overestimate in conditions of a dry climate, water scarcity and the use of outdated technologies for the extraction of solid minerals. This article examines the ecologic-geomorphological situations of mining areas of arid platform-denudation plains of Kazakhstan and gives their characteristics, which is based on an analysis of the leading natural and anthropogenically caused geodynamic processes, their spatial coverage, ratios and comparative assessment as an indicator of geomorphological risk within selected morphogenetic types of relief.

Highlights

The analysis of the ecological and geomorphological situation and the assessment of geomorphological risks associated with anthropogenic activity is one of the main tasks of geoecology, and causes great scientific and practical interest
The objective of this study was to study the problem of the formation of dangerous geomorphological situations and associated geomorphological risks within the platform-denudation plains of the arid zone of Kazakhstan, the territory of which is rich in mineral resources and has been actively developed since the 30s of the XXth century
The relevance of the problem under study is caused by the fact that the ongoing mining of surface and underground character is the cause of the deterioration of the general environmental situation, the increasing potential of geomorphological risks in the region, and the health of the population, which is a necessary basis for modern economic development of both Central and all Kazakhstan

Summary

Introduction

The analysis of the ecological and geomorphological situation and the assessment of geomorphological risks associated with anthropogenic activity is one of the main tasks of geoecology, and causes great scientific and practical interest. The geomorphological environment is not static, it changes in time and space by geodynamic processes. Changes in this environment, caused by the activation of geodynamic processes and, the redistribution of the products of destruction of rocks, are usually called geomorphodynamics. Undesirable geomorphodynamic situations can generate geomorphological risks, which, in this case, are designated as risks to human life and life, arising from damage caused by dangerous geodynamic processes and phenomena, both natural and anthropogenic in nature. The objective of this study was to study the problem of the formation of dangerous geomorphological situations and associated geomorphological risks within the platform-denudation plains of the arid zone of Kazakhstan, the territory of which is rich in mineral resources and has been actively developed since the 30s of the XXth century. The relevance of the problem under study is caused by the fact that the ongoing mining of surface and underground character is the cause of the deterioration of the general environmental situation, the increasing potential of geomorphological risks in the region, and the health of the population, which is a necessary basis for modern economic development of both Central and all Kazakhstan
