Abstract

The paper considers one of the most dangerous slope exogenous processes formed on the rock dumps of coal mining enterprises landslides-flows. The mechanism of occurrence, movement and accumulation of landslides-flows, mechanisms of negative impact on objects and territories is described. The factors of activation of landslides-flows on rock dumps of coal mining enterprises (anthropogenic, meteorological, hydrological, hydrogeological and geological factors).

Highlights

Production processes of mining enterprises are associated with the movement of significant volumes of rocks: their loosening, mining, sorting, transportation, storage and further processing
On these territories there is a violation of natural landscapes and the formation of special man-made landscapes, represented by various elements of the relief of anthropogenic origin: quarries, rock dumps, waste piles, tailings, man-made deserts, etc
Technogenic soils involved in the formation of these landscapes are characterized by a decrease in the total number of rigid structural bonds and an increased content of fine dust particles in connection with the use, during mining and overburden removal drilling and blasting and mechanical methods of disintegration of rocks

Summary

Introduction

Production processes of mining enterprises are associated with the movement of significant volumes of rocks: their loosening, mining, sorting, transportation, storage and further processing (if necessary). Technogenic soils involved in the formation of these landscapes are characterized by a decrease in the total number of rigid structural bonds and an increased content of fine dust particles in connection with the use, during mining and overburden removal drilling and blasting and mechanical methods of disintegration of rocks These circumstances cause the active involvement of man-made soils in dangerous slope exogenous processes of gravitational, water-gravity and fluvial nature (landslides, falls, debris flows, etc.). It is especially worth noting the rock dumps of coal mining enterprises, which in addition to large volumes of storage is characterized by a long period of their operation due to the long time of development of the field. As well as manifestations of dangerous exogenous processes on the rock dumps of coal mining enterprises, the consequences can be catastrophic
