Abstract In the case of underground mining of mineral deposits under difficult mining and geological conditions and at great depths, one of the most urgent problems is the prevention of dangerous geodynamic events. The use of digital elevation models significantly expands the possibilities of preliminary assessment of the potential hazard of their manifestation. This article discusses the results of an assessment of the neotectonics and geodynamics of the Streltsovsky ore region carried out using digital elevation models. The interpretation of the obtained data is based on the concept of lateral tectonic flows adapted for the Far Eastern region of Russia. Digital elevation models based on the GTOPO30 made it possible to identify and evaluate the drift direction of three tectonic flows in the region. The direction determined by the relief coincides satisfactorily with the GPS direction.

The Kuhn-Magnyo copper-nickel deposit is located in the southeast of the Aldan-Stanovoy shield. Based on the results of geological exploration, the object is assessed as promising. The ore field, within which the deposit is located, is confined to a complex junction of several regional tectonic structures. The area has an intensely dissected relief, increased seismicity. Therefore, an assessment of the possibility of dangerous geodynamic phenomena during its operation is required. This work describes its preliminary assessment based on the results of morphometry on digital elevation models (DEM). Several morphostructural elements have been identified that directly determine the geodynamics in the area of the earth’s crust containing the deposit. The result of the study revealed a potential hazard.

The downy mildew (peronosporosis) is the most dangerous and harmful cucumber disease in the Far-Eastern region. Its harmfulness is the highest during the period of flowering – fruiting, because it may completely ruin the cucumber plants both in open and protected ground. Use of cucumber sorts with effective genes that are resistant to the disease is the most efficient way to fight cucumber peronosporosis. In this connection the publication adduces the facts of study the sorts and hybrids of different ecological and geographical origin from the genetic resources collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) in comparison with three zoned sorts of DV NIISH selection – Mig, Khabar, Amurchonok. The aim of researches – to identify the sort samples cucumber according to the main economically valuable traits and also to the degree resistance of genetypes to the main disease of the culture in the region – downy mildew (peronosporosis), for allow to select the source material for the creation of sorts and hybrids, highly productive and resistant to biotic and abiotic stress environmental factors in the monsoon climate conditions of Khabarovsk region. The perspective genetypes having both the resistance to the diseases and productivity are not revealed as a result of the evaluation of the collection of cucumber samples according to their susceptibility by fungus diseases and productivity. Slavyanskiy (Belarus) is more resistant to peronosporosis, especially in 2016 year conditions, although it was inferior to the damage degree of disease to the zoned sorts – Mig, Khabar, Amurchonok. This perspective sample is planned to be used as a source of donors of the main economically valuable traits in a further selective work.
