With the shallow resources dwindling, many countries have entered into deep mining one
after another. Rock fracture caused by high stress mining disturbances is a significant …

Subsidence data acquisition methods are crucial to mining subsidence research and an
essential component of achieving the goal of environmentally friendly coal mining. The …

Conventional discrete fracture network (DFN) modeling is used to simulate hydraulic fracture
propagation in fractured low permeability reservoirs. However, natural fractures have a …

In the mining process of close distance outburst coal seams, a large amount of gas is
desorbed and discharged into the atmosphere causing the waste of coal bed gas resource …

Many gas pre-drainage boreholes are generally constructed in coal seams to ensure safe
underground operation. True triaxial experiments were conducted to study the mechanical …

During the exploitation of deep resources, rock masses are under three-dimensional
anisotropic stress conditions owing to tectonic conditions and engineering disturbances …

In view of the problem that the broken stope roof under repeated mining is prone to end face
roof leaks, this paper's research background is the close distance coal seams mining of a …

The quantitative prediction for a coal burst is challenging since the coal burst mechanism is
extremely complex with a verity of influencing factors involved. This study proposes a data …

Heat injection is a new method of recovering enhanced coalbed methane (ECBM). In this
study, the impact of a sudden increase in ambient temperature on the permeability of coal …

The purpose of this study was to measure internal longitudinal displacements taking place
during tunnel excavation and compare them to the displacements predicted using available …
