Rekultywacja terenów poeksploatacyjnych w Kopalni Dolomitu „Radkowice” w Radkowicach

Jednym z najistotniejszych działań na rzecz ochrony środowiska w kopalniach odkrywkowych jest rekultywacja terenów pogórniczych. Składają się na nią przedsięwzięcia projektowo-techniczne i organizacyjno-wykonawcze, których celem jest przywrócenie terenom pogórniczym właściwości użytkowych i przyrodniczych. Z uwagi na to artykuł prezentuje sposób i zakres wykonania prac likwidacyjno-rekultywacyjnych oraz efekty rekultywacji terenów poeksploatacyjnych w Kopalni Dolomitu „Radkowice”.

One of the most important environmental protection measures in open-cast mines is the reclamation of post-mining areas. In 2018, after mining the Radkowice-Podwole deposit, the reclamation of the excavation began – and the areas surrounding it to make it a place with water – in order to make it a place with a forest and make it a place with grass, trees, and bushes. The reclamation aims to accumulate groundwater and to create a water reservoir in the excavation with the surface elevation of +220 to +221 m above sea level. As a result, the groundwater level will be increased, while the Bobrza river will change from being the supplying river back to the draining river. As part of the technical reclamation of the excavation, protective slopes were created from the western and north-eastern side. They were created at an angle of 12° to the elevation of +224 m above sea level, and at an angle of 25° at higher elevations. This process ensured the stability of the excavation and improved the landscape surrounding it. The amount of material used to build slopes in the western and north-eastern side was 800,000 m3. Other slopes are entirely rocky and they did not require stabilisation. A backwash filter from local rock material was created at the point of contact between the slopes and the planned water levels. Different species of trees and bushes were planted in the areas after former dumping grounds. As a result of the reclamation activities, the post-mining areas after the operation of the „Radkowice” Dolomite Mine at the Radkowice-Podwole deposit were organised, which gives them a chance to be used for another purpose, and by creating a water reservoir the commune undoubtedly became more appealing to tourists. The reclamation of the excavation is still in progress. It is assumed to be completed in 2023 r.
