Typical Pore Characteristics of Nontectonic and Tectonic Low-Rank Lignite in Mining Areas and Their Influence on Gas Desorption

Abstract Pore characteristics determine the control mechanism of gas adsorption and desorption in the coal bodies. The fundamental investigation into microscopic pore structures and adsorption–desorption characteristics of long-flame coal represents necessary support for the safe...

Experimental Investigation and Response Surface Optimization of Fiber-Reinforced Polymer Concrete for Mining Roadway Support

The escalating intensity and depth of coal mining operations have exacerbated underground strata pressure, resulting in fracture-induced air leakage channels that heighten risks of coal spontaneous combustion and gas explosions. These challenges necessitate enhanced flexibility a...
