Sažetak
Smaller open pits, which are common in Croatia, can be used for sanitary dumping of communal waste. The volume of successively excavated mineral resources (such as clay, coal, gypsum etc.) can be filled in by waste and the sterile excavated masses of either the overburden or interburden - soil, clayey interbeds or other fine-grained fractions, can be used to cover the waste. After filling in the quarries with waste and overburden, the original landscape can sometimes be restored. The available mining machinery can be fully utilized in waste re-loading and dumping as well as the manpower and supervisory services. This activity could be a source of additional income for the mine, especially when costs of the area/volume used are calculated, together with the costs of covering the waste with overburden material, as well as the machinery, manpower and supervision. All of the mentioned components have to be validated in order to complete the process safely and in time. Multiple effects could be achieved in this way. The waste is completely removed from the landscape, the less dense components of the waste (paper, plastic etc.) can’ t be blown away, and the self-heating process is suppressed. Also, there is no air pollution, and the groundwater and soil can be protected as well, with additional protective measures taken in accordance with the material and properties of the surrounding rocks. The testing object is an active clay pit in eastern Croatia that produces approximately 100, 000 m3/yr, which are used in a brickyard. The mine also excavates a quantity of 30, 000 m3 of overburden and interburden. There is a plan to dump approximately 20, 000 m3/yr of communal waste, in the course of daily mining operation. To this purpose, a system of the cassette waste dumping with the regulatory protective measures is planned. Finally, a sport-recreational complex could be built on the site, because the mine is in close vicinity of a town with 50, 000 inhabitants.
