Abstract
Exploratory waste, which is created in the course of mining activities, constitutes more than half of all wastes produced in Poland. In majority, they are considered inert, i.e. harmless for the environment, which enables them to be employed in reclamation of degraded areas. However, the lack of basic nutrients and inappropriate granulometric composition necessitates the introduction of components which remove these limitations. The aim of the conducted research was assessing the possibility of producing mechanically and chemically stable soil-like material out of compost from municipal waste and exploratory waste: coal gangue and drill cuttings from shale gas exploration. Physicochemical properties of the created mixtures were investigated, and their impact on the growth of test plant – common wheat – was evaluated. It was observed that the mineral component, which comprised coal gangue and drill cuttings mixed in the weight ratio of 10:1, was a significant source of potassium, whereas the compost yielded nitrogen and improved the physical properties determining the adequate water-air relations. The best conditions for the growth of the best plants were achieved with the mixture consisting in 50% of compost and 50% of mineral component.
