Effect of filling materials on reclaimed soil potassium adsorption and desorption in mining area

Meitan xuebao
Coal mining causes land subsidence, soil degradation, and nutrient depletion in agricultural areas. Filling and reclamation with various materials is a common method for restoring subsided land in the eastern mining areas of China.

Effects of Underground Mining on Soil–Vegetation System: A Case Study of Different Subsidence Areas

Ecosystem Health and Sustainability, 2023
The influence of coal mining subsidence on the surface ecological environment can be characterized as the evolution of a complex system. Examining the ecological damage caused by coal mining subsidence from the perspective of internal soil–vegetation ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

Advanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Study on the destruction law of physical and shear properties of soil in mining disturbance

Scientific Reports, 2023
Underground mining activities can easily trigger surface subsidence and cause damage to surface soil. However, there is still a lack of studies on damaged soil, restricting ecological remediation in mining-induced subsidence regions to a certain degree ...

Food insecurity and unemployment among immigrants in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Surface Subsidence Prediction Method for Coal Mines with Ultrathick and Hard Stratum

Advances in Civil Engineering, 2019
Overburden conditions consisting of ultrathick and hard stratum (UTHS) are widespread in China and other countries, but existing surface subsidence prediction methods ignore the strong impact of UTHS on surface subsidence.
