Based on the damage analysis of elliptical aperture, the mechanism of coal dam-age in the developing process of coal and gas outburst was researched. The results show that the damage to coal by gas is mainly caused by the concentrated tensile stress appea
Stress distribution rules and deformation and failure properties of coal and rock bodies influenced by mining were analyzed. Experimental research on permeability of coal and rock samples under different loading conditions was finished in the laboratory.
A new biofilter technology was used to control the methane concentration in the coal mine. The results indicate that the biofilter achieves a steady methane removal capacity of 1 470mg/(L·h)after 30 days start-up. More than 90% of the methane can be remov
Using self-developed gas-seepage experimental installation, under the same effective stress conditions, coal permeability experiments on different adsorption charac-teristics of gases, different temperatures and different gas adsorption contents were per-
By analyzing the characteristics and the production mechanism of rock burst that goes with abnormal gas emission in deep coal seams, the essential method of elimi-nating abnormal gas emission by eliminating the occurrence of rock burst or depressing the m

Control effect of fracture on hard coal cracking in a fully mechanized longwall top coal caving face
Through theoretical analysis,simulation test and practice,the law of a fracture\'s influence on hard top coal press cracking was studied.The study focused on the relation between fracture and coal strength,top coal caving ability and work face layout.Ba
According to fluid dynamics analysis during the fire, the criteria k-ε two-equation model for solving three-dimensional turbulence was determined, the pollutants generated in the fire disaster were set by adopting Mixture multiphase flow, and the SIMPLE a
Mine gas extraction in China is difficult due to the characteristics such as mi-cro-porosity, low-permeability and high adsorption of coal seams. The pulsed mechanism of a high-pressure pulsed water jet was studied through theoretical analysis, experiment
