Abstract Ever since the commencement of industrial-scale coal mining (in northeast England around 1600), substantial environmental impacts have been recorded as arising from both the mined voids and from the wastes left behind at the surface. In the early days of coal mining, complaints about such impacts were strident, as the newly established …
37 coal mining wastes have been viewed as problematic geomaterials. They are chemically Journal of Cleaner Production, Submitted Oct 2021; Published Dec 2021.
The term mine waste implies that the material has no current economic value and is an unwanted by-product of mining. However, some mine wastes can be useful and this has been recognized since the beginning of mining and smelting . For example, the use of slag in road construction can be traced back to the very early days when the …
