Abstract The number of abandoned mines is continuously increasing in the world. sustainable exploitation these a top priority globally. Pit lakes created mining sites provide benefits and present risks for region. This paper presents methodology to assess natural hazards related pit lakes. proposed framework based on well-established internationally accepted risk management standards allows ass...

Yannan Coal Mine in Dayan Mining Area creatively utilizes water-preserving mining technology to block abandoned roadways build underground reservoirs and sedimentation tanks. It implements a zoned utilization management optimization technical plan for mine water, so that it can meet the needs of working face production surface domestic water use. This comprehensively recycles conservation makes...

In this study, we collected rhizosphere soils and root samples from a post-mining area and a natural forest area in Jecheon, Korea. We extracted spores of arbuscular mycorrhizal fungi (AMF) from rhizospheres, and then examined the sequences of 18S rDNA genes of the AMF from the collected roots of plants. We compared the AMF communities in the post-mining area and the natural forest area by sequ...

In order to elaborate the concept of an industrial ecosystem for circular economy old coal mining regions in Ukraine, we apply Corrine Beaumont's Lean Tribe Canvas model. The is based on combination several approaches, including smart shrinking, urban mines, specialisation. main idea this organize integrated processing accumulated waste and enrichment decades using innovative technologies retri...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...
