In recent years, the ecology, security, and sustainable development of modern mines have
become the theme of coal mine development worldwide. However, spontaneous …

In order to further improve an air curtain's dust suppression performance in tunnels, this
paper made an in-depth analysis of the effects of an air curtain generator's radial and axial …

Coal spontaneous combustion results from a complex reaction between coal and oxygen.
Previous studies on coal oxidation spontaneous combustion process provided guidance for …

In underground mining, rock roofs with different thicknesses have distinct failure patterns
under the complex stress. To understand the height/diameter ratio (H/D) on failure properties …

As coal mining proceeds deeper, coal and rock are subjected to growing stresses and gas
pressures. Consequently, coal and rock gas dynamic disasters pose more and more …

High temperature causes thermal damage to rock; the macrofracture and microfracture of
rock can be produced under the action of temperature treatment. Under the influence of high …

A microseismic (MS) monitoring system in a mine can monitor the MS signals generated by
coal rock rupture and blasting waves and can distinguish the two types of waves more …

Geological dynamic hazards during coal mining can be caused by the structural instability of
a composite system of roof rock and coal layers, and joints in coal play a vital role in this …

In this work, three different activated carbons were prepared from low-rank bituminous coal
by KOH activation method. High-pressure methane adsorption tests were conducted to …

The frequent occurrence of rockburst and the difficulty in predicting were considered in deep
engineering and underground engineering. In this work, laboratory experiments on …
