Coal gangue is an abandoned rock discharged during coal mining and processing. When mining coal, the rock layers or bottom plates from the roof of the coal seam, as well as the various types of rock excavated and blasted from around the coal seam during the excavation are all …
Using coal gangue as subgrade filler (CGSF) can address the accumulated issues of coal mine waste, but also save the constructing costs, which has the important ecological …
Synergy of 10 % fly ash-cement slurry encapsulation and CO 2 mineralization improved the mechanical properties of coal gangue. CO 2 mineralization enhanced the …
In this paper, for coal gangue coarse-grained subgrade fillers, particle crushing tests were carried out, and the relationships between load and displacement, crushing …
The high porosity and porous nature of coal gangue increase soil pore space, enhancing soil aeration and water holding capacity. This promotes root development and …
In this paper, the compression and fractal test of graded crushed gangue is based on fractal theory.
Crushed gangue backfilling material (CGBM) is most commonly used as a kind of solid backfill material for SBCM. When it is filled into the goaf, the phenomenon of particle crushing occurs in the process of cyclic …
In this research, the deformation, particle crushing, and morphology evolution of saturated crushed gangue under variable axial stresses (0, 2, 4, 8, 12, 16, and 20 MPa) were …
In order to increase the crushing rate of coal gangue coarse particles during tamping, improve the fine-rough ratio, and improve the physical and mechanical properties of …
The modified coal gangue not only serves as a multi-nutrient source, providing essential nutrients for the soil, but also acts as an effective soil amendment in rehabilitating …
