With the extraction of mineral resources a significant volume of solid waste including tailings TS and coal gangue CG has been generated resulting in severe environmental pollution and safety hazards [1] [2] [3] [4] The comprehensive utilization of solid waste has perennially been a focal point within the field of mining engineering [5]
In China the reclamation of coal mining subsidence land began in the late 1970s At present coal gangue filling reclamation is an important means for mining land reclamation Li et al 2020 Coal gangues are backfilled and covered with soil in subsidence areas to reconstruct mining disturbed soil which serves the dual effect of mineral processing waste disposal and
The coal gangue and fly ash used in the experiments were collected from a gangue dump and a power plant in the Coal Mine respectively In practical applications due to the limitations of the backfill process and equipment only gangue with a particle size of 50 mm or less is generally used for backfill Li et al 2017 Li et al 2017
Coal gangue CG is an associated product in the process of coal mining and washing accounting for approximately 10 15% of the raw coal production and in some small and medium sized coal mines
Whether the application technology of coal crusher is stable in coal mining will directly affect the economic benefits and profits of coal enterprises The crusher manufacture and development are closely related to power machineries such as electric motor and steam engine The coal mine crusher development with power machinery development The
more water and can be easily transported by the pipeline system A special designed jaw crusher was used to crush coal gangue Two stages were needed before the coal gangue particle size reached the demanded size <25 mm In the first stage coal gangue was crushed into sizes between 25 mm and 50 mm
The large scale open air storage of coal gangue often leads to oxidation and decomposition due to natural weathering resulting in decreased strength and instability which limits its wider application in concrete pavement To address these issues this paper proposed a composite consolidation treatment for weathered coal gangue WCG assessing its
