As such, this paper provides a detailed overview of the physical and chemical properties of coal gangue and its resource utilization methods in the environmental field, particularly in soil remediation, soil reclamation, the preparation of adsorbents for heavy metals, dyes, and CO 2, and as catalysts for organic degradation and catalytic ...

Coal gangue, a solid waste generated from coal mining, contains nutrients and trace elements comparable to those in soil, making it a promising covering material. This study …

The present study specifically focused on the substrate ratio, aiming to 1) determine the optimal amounts of water-retaining agent, bentonite, and coal gangue to be mixed with …

Our objective was to test the influence of different thicknesses and particle sizes of coal gangue mulch on soil water infiltration and evaporation and to determine an optimized …

Coal gangue has a higher bulk density than typical soil and fewer capillary pores; its incorporation into soil enhances soil aeration and porosity, providing certain nutritional components but struggling to form soil aggregates and lacking active microbes.

Coal gangue, a solid waste generated from coal mining, contains nutrients and trace elements comparable to those in soil, making it a promising covering material. This study investigates the effects and mechanisms of coal gangue coverage on the physicochemical properties of soil, enzyme activity, and the growth of ryegrass.

A pot experiment was conducted to test the effects of coal gangue and garden soil treatments on morphological, photosynthetic and biochemical characteristics of R. delavayi cultivation, and substrate properties in six different ratio (9:1, 8:2, …

Coal gangue has a higher bulk density than typical soil and fewer capillary pores; its incorporation into soil enhances soil aeration and porosity, providing certain nutritional components but struggling to form soil aggregates and lacking active microbes.

The present study specifically focused on the substrate ratio, aiming to 1) determine the optimal amounts of water-retaining agent, bentonite, and coal gangue to be mixed with topsoil soil (sandstone soil) and 2) provide a practical method for vegetation restoration in arid mining areas based on modified soil substrates.

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 …

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 …

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 degraded soils such as sandy soil, heavy metal-contaminated soil.

Our objective was to test the influence of different thicknesses and particle sizes of coal gangue mulch on soil water infiltration and evaporation and to determine an optimized design for coal gangue mulch.

The crushed gangue is ground into powder and sent to be refined into bricks. In addition to the above 7 uses, coal gangue can also been found the uses in porous ceramics, soil conditioners, water treatment adsorbents, and power generation, etc.

A pot experiment was conducted to test the effects of coal gangue and garden soil treatments on morphological, photosynthetic and biochemical characteristics of R. delavayi …

Coal gangue occupies large swathes of land resources, resulting in ecological fragility and various environmental problems. Despite coal gangue having mineral elements similar to those in soil,...
