To determine the effect of air flowrate on pollutant dispersion pattern of coal dust particles at
the fully mechanized mining face, the present study aims to reduce the dust concentration …

Rigorous coupling of fracture–porous medium fluid flow and topologically complex fracture
propagation is of great scientific interest in geotechnical and biomechanical applications. In …

Gob-side entry driving near an advancing working face can improve the recovery rate of coal
resources and keep the balance between mining and development. However, the large …

Porosity significantly affects the dynamic response of water-saturated coal and the safety of
coal mine engineering in water-rich areas. For mastering the dynamic response of water …

The mechanical and acoustic emission characteristics of rock-like materials under non-
uniform loads were investigated by means of a self-developed mining-induced stress testing …

A new energy-dissipation method to identify crack initiation and propagation thresholds is
introduced. Conventional and cyclic loading–unloading triaxial compression tests and …

Entry driven along goaf-side (EDG), which is the development of an entry of the next
longwall panel along the goaf-side and the isolation of the entry from the goaf with a small …

Study of movement characteristics of a hard–thick stratum (HTS) affected by a fault in a
coalmine is significant to predict the dynamic hazards (ie, rock bursts and shock bumps) …

Our main scheme in this study was distinguishing between fracture porosity and matrix
porosity in coalbed methane reservoirs through a novel approach which is the joint usage of …

This paper presents an integrated approach for field test and numerical modelling to
investigate the relationship between gateroad stability and yield pillar size. The test site is …
