Restoration of Mined Areas | Ecological Restoration

Pandey suggested a holistic strategy for restoration of mine-spoils. The strategy includes: 1. Policy measures and incentive mechanism to store fertile top-soil layer for use in post-mining restoration operation, 2. Protection to adjacent refugia, remnant vegetation and ancient trees, 3. Attracting seed dispersers, 4. Rainwater harvesting, 5.

Restoration priority assessment of coal mining

Coal is the main energy source in China, but the share of coal consumption in the energy mix has declined from 71.5% in 2008 to 59.0% in 2018 (National Bureau of Statistics of China, 2019). As China increases the clean energy consumption, more and more coal mines that are unsafe, polluting, or wasteful are continually being shut down.

Coal fines have traditionally been an unwanted by‐product in the coal mining industry and remain a major disposal challenge. The coal fines business was established to tackle this challenge. MRI commissioned a 5,000 tonne per annum screening, agglomerating and briquetting operation near Vryheid in February 2014 to process the waste dump and current tailings of the Keaton's Vaalkrantz Colliery.

Analysis of Plant and Soil Restoration Process

Vegetation and soil restoration are the key to ecological reconstruction in the damaged areas of open-pit coal mining areas. Ecological stability is an important indicator of the degree of ecological restoration. In this study, the ecological stability and the process of plant and soil restoration were investigated at different refuse dumps in three coal mines, namely, the Wulanhada (WLHD
