Coal mining wastes valorization as raw geomaterials in
The state-dependent properties of coal mining wastes (e.g., water retention, hydraulic conductivity, shear strength) are found to be governed by complex During the coal mining process, a significant amount of coal wastes is produced, including (1) mining wastes, (2) washery wastes, and (3) secondary Coal wastes: handling, pollution, impacts, and utilization

A systematic review exploring the utilization of coal mining
Surface/open cast mining and deep underground mining are considered two basic methods for coal extraction globally. The rising trend of coal mining activities has resulted in the accumulation of mining and processing wastes with low carbon levels over the past few decades [6]. Fig. 1 presents different life cycle stages of coal with details of Abstract and Figures. Coal mine spoils (CMSs), the solid wastes originated from the rock formations and soil cover overlying or interbedded with coal seams, are a worldwide environmental(PDF) Understanding the salinity issue of coal mine spoils in

Coal mine wastes recycling for coal recovery and eco
The mining industry is globally criticized for generating large amount of solid wastes often with a potential environmental impact. This study presents a feasible approach of recovering residual coal from coal mine waste rocks (CMWR) and reusing the derived tailings to produce ecofriendly fired bricks. The first step aims at the production ofIn China, coal mining wastes have traditionally been dumped in cone-shaped heaps that have the potential to pollute air, soil and water environments and landscapes through dust generation, leachate production, self-ignition and as a consequence of an absence of vegetation cover. Since 1980s, the disposal technique for The impact of disposal and treatment of coal mining wastes

Potential resources from coal mining and combustion waste
Coal production presents major sustainability challenges as it continually generates large amounts of waste, in addition to previously accumulated waste that have flow-on adverse effects on society and the environment. We have explored some of the opportunities for repurposing, reusing, reprocessing or recycling discards of the coal Coal mining wastes weather rapidly when exposed to the elements (Bishop, 1973; Skarżyńska, 1995a) but may remain relatively intact when buried deeply within an unburnt spoil heap (Taylor, 1975), thus depending on various factors (e.g., how the original wastes were processed and deposited, how long they have been left there, Coal mining wastes valorization as raw geomaterials in

Recycling utilization patterns of coal mining waste in China
Fly-ash and coal gangue are the two main industrial solid waste in China. The chemical compositions (shown in Table 1) were SiO 2, Al 2 O 3, Fe 2 O 3 and some impurities. As the coal gangue is main solid waste for coal mining, one of the most common approaches to waste rock is to stack construction that encapsulate the most pyrite rich One of these lines of research is based on coal mining waste, which once activated thermally, it becomes a highly pozzolanic product (ACM).

The Challenges of Reusing Mining and Mineral-Processing Wastes
The origin of mining and mineral-processing wastes is closely related to the formation of the target resource or minerals. For example, many coal deposits exist in subsided regions resulting from mountain formation; hence, the overlays of coal resources are generally not very thick and consist of relatively inactive sedimentary rocks.CMWs (coal mine wastes) as the waste products of coal exploitation or washing plants are a source of pollution that generates waste management problems, especially those that are very old and without a known owner. CMW chemical composition indicates that it contains SiO2-Al2O3-Fe2O3 in such percentages that it can be used in Feasibility study on the utilization of coal mining waste for
