The ecological consequences of long-term development of coal deposits for the components of the environment, buildings, communications and infrastructure facilities have been analysed. The stress-deformed state of the rock massif around the preparatory working in the development of multiple coal layers is determined. The parameters of the development of the contiguous layers in the conditions of the mines of the Lviv-Volyn Coal Basin are substantiated. The complex of nature protection measures allowing to reduce the negative consequences of disturbance of the earth’s surface in the development of multiple coal layers is substantiated.

The ecological consequences of underground coal mining and the mechanisms of transformation of the rock mass and the earth's surface are determined. To increase the efficiency of environmental activities of coal mining enterprises, the expediency of introducing the technology of stowing of the worked-out areas with grouting solutions using rock from dumps, ash, waste from coal processing plants is substantiated. The implementation of the proposed technological solutions will ensure the protection of land, buildings and structures from under-mining, as well as improve the environmental situation in coal mining regions.

Many years of coal production have led to significant changes in the stability of the rock mass and the earth's surface in the territory of the coal mining regions of Ukraine. The reasons for such changes are the increase of fracture and decrease of the strength of rocks, stratification and hanging of rocks in the boundary parts of workings, the presence of interstices in the coal-face workings, large-scale subsidence of the earth's surface, underworking of a considerable number of buildings, structures and infrastructure.
