PROPAGATION OF THE DANGEROUS GEOLOGICAL PROCESSES IN DNIPROPETROVSK REGION

Recently the actuallity of geological study in the city territory stipulate for the intensification of construction and the necessity of risk assessment of a display of dangerous geological processes. A technogenic load on the geological environment is increased in many times over in new construction, reconstruction of the old building, intensive learning of the subterranean space, accordingly the geological and hydro-geological conditions are fundamentally changed. So the natural groundwater regime (layered, temperature and hydrogeochemical) is broken, that frequently lead to for-mation or activation of the negative engineering-geological processes and the formation of the emergencies. The eco-nomic loss as the result of dangerous geological processes are enormous. Objective. To make the data analysis of a long-term monitoring of the dangerous geological processes (underflooding and landslides) on the territory of Dniprope-trovsk region. Conclusion. An assessment of the existent natural-technogenic situation and a forecasting of the chang-es of engineering-geological conditions is almost impossible without detailed study of the territory. In recent years the number of sites of an existent observation system for last years has been reduced: there were 334 plots in 1994 (on average every plot falls at 1800 km2), 215 were in 1999 (one plot at 3000 km2) and still are lasting. A shortage of the plots of observation is felt especially in the regions of the intensive technogenic influence is on the territory of the enter-prises of mining industry, industrial-urban agglomerations etc. The observational data on these plots would assist in timely reaction on the activation of the exogenic dangerous processes, i.e. on the prevention of the formation of the emergencies, instead of liquidation of their consequences. The dynamics of the process of underflooding remains progressive. The last data shows the tendency of the activation of the process in the regional scale and about the in-creasing of underflooding surface (from 7260 km2 in 2007 to 7290 km2 in 2014), that activates the processes of the landslides generation (only in Dnipropetrovsk 214 landslides were fixed in 1982, 314 were in 2002, 382 were in 2014). In recent years the complications of a geological situation were noted, first of all it affects the activation of the land-slides and underflooding. Therefore the study of the conditions of development, expansion and activation of the dan-gerous geological processes and also organization to observe them stands in a row of the first-priority and the urgent questions.
