English abstract

This paper covers topical issues of groundwater and surface water inflow depending on the quarry field spatial dimensions, which leads to an increase in the costs of dewatering and drainage. The spatial dimensions of a quarry field are one of the key indicators in determining the appropriate depth of mining the deposits of hard-rock building materials. The theoretical research is performed using the following methods: statistical and analytical research method for analyzing the hydrological characteristics of non-metallic deposits and their parameters; graphic-analytical method for determining the area of the quarry walls from which water flows due to groundwater and atmospheric precipitation; technical-economic method for assessing the patterns of changes in costs for dewatering the quarry depth; and method of options for selecting the type of water drainage equipment. As a result, patterns have been obtained that characterize the change in the normative inflow of atmospheric precipitation depending on the quarry field area and the change in the unit costs for dewatering depending on the type of the studied quarry field. The practical significance of the conducted research is to use the obtained results of developed design solutions, tested and implemented in the scientific-technical (project) documentation for the mining conditions of Sofiivskyi, Mykytivskyi, Boleslavchykskyi, Chaplinskyi, and Lyubimivskyi fields of non-metallic hard- rock minerals
