Deep Underground Science and Engineering, EarlyView.In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

I. A coal-dust explosion [PDF]
Proceedings of the Royal Society of London, 1887 Abstract The Silkstone pits of Altoft’s Colliery, near Normanton, in Yorkshire, in which the explosion took place, are 420 yards deep. Both shafts are round, the down-cast being 12 feet and the up-cast 10 feet in diameter. The thickness of the working, including a bed of soft shale below the seam, used as a holing, is 4 feet 6 inches.

Dynamic cracking properties and generating conditions of coal under rapid gas release
Deep Underground Science and Engineering, EarlyView.Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Deep Underground Science and Engineering, EarlyView.This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Float coal dust explosion hazards [PDF]
"In underground coal mining, dust is produced at the face, at conveyors, at transfer points, and by the normal movement of workers and machines. The coarse coal dust particles settle rapidly.

Geological Journal, EarlyView.This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Relation of Coal-Dust to Explosions in Coal-Mines [PDF]
Nature, 1886 IT is a stubborn and grievous fact that the loss of life by explosions in coal-mines has risen in the last decade, although the number of explosions has fallen. This points clearly to some essential defect in the remedies adopted. The remedies in use apply apparently to one class of explosions only, hence the decrease in the number of explosions.
