This paper presents an attempt to analyze the modern influence of underground mining on geoecological environment. The coal mine, from the point of view of environmental impact, is a complex composed of overground and underground parts, each of them having influence on a biosphere. The basic directions of negative influence are the following: withdrawal of land from usage and disturbance of lands; exhausting of water resources and disturbance of surface waters regimes; pollution of surface waters; pollution of a surface by wastes of a mining and coal preparation; relief deformation and creation of technogenic landscapes. Detailed monitoring of geoenvironment is necessary to avoid negative influence of underground coal mining industry.
