Igneous rock often appears in coal measure strata, and its occurrence, size, and distribution
play important roles in mining safety. The failure of hard and thick igneous rocks can result in …

Spontaneous imbibition is a process of effectively wetting coal pores, which can improve
wetting uniformity. Therefore, spontaneous imbibition is critical for outburst, dust and …

This work aimed at revealing the mechanism of strong ground pressure behaviour (SGPB)
induced by high-position hard roof (HHR). Based on the supporting structures model of …

The grand-scale suspended roofs overlying the goaf are commonly developed under thick-
hard rock strata (THRS) during the mining process of the deep coal seam. As a result, strong …

With the increase of coal extracting depth, a considerable number of dynamic disasters
display the co-occurrence and coupling effect of rockburst and coal–gas outburst, which is …

Coal burst is one of the hazardous events that mining engineers have been struggling with it
since past decades. This phenomenon has sudden and violent nature and almost occurs …

An increasing number of mines in China are being subjected to overall-instability-induced
(OII) rockbursts in extracting deep remnant island longwall panels, causing severe damage …

Samples composed of coal and rock show different mechanical properties of the pure coal
or rock mass. For the same coal seam with different surrounding rocks, the frequency and …

As one of coal mine dynamic disasters, rockbursts generally result in abrupt displacements
and unpredictable coal rock failures with disastrous consequences and pose serious threats …

By comparing the overburden structure characteristics and the distribution of stresses
around roadways and coalfaces in slice mining and top-coal caving mining in thick coal …
