Research of the impact of open-pit mining on the land and water resources in Kryvbas

Main effects of mining operations on the land and water resources while mineral are considered. Identify that intensive open-pit underground development deposits has resulted in disturbed natural environment, which, turn, have changed geomorphological hydrogeological structure region. Current stage determined terms Kryvyi Rih iron-ore basin. The analysis showed аs a result technical activities Kryvbas, minimum 15-20 mln ha disturbed, 59 % this area is used for different mine workings, 38 covered with waste rock dumping or from concentration, 3 sites subsidence, caving, other surface disturbances due to mining. Thus, about 1 km3 drainage extracted annually during extraction. As result, landscapes been replaced by new technogenic objects, Key technological objects largest enterprises Kryvbas industry as well their parameters studied. Dynamics accumulation emissions discharges production wastes basin location shown. means gross discharge contaminating substances. On average, more than 235.62 thous. t/year enter air dust. Also identify Region average 2296.8 m3/year contaminated water. Certain measures proposed facilitate reduction impact indicated environmental components. They aimed at involve implementation resource-saving technologies along reclamation objects. Keywords: operations, impact, object, dump, resources, resources.
