Study on Occurrence Mechanism of Coal Pillar in L-Shaped Zone during Fully Mechanized Mining Period and Prevention Technology
Published 2021-01-01“…The results show that a coal pillar with some confining pressure in the L-shaped zone is established by FLAC3D numerical simulation software, and the numerical simulation results indicate that the change in static load has a greater effect than dynamic load on coal pillar unstable failure; the static load plays a role in storing energy, and dynamic load plays a role in inducing rock burst; the bolt-mesh-cable support and high-pressure water jet unloading combined technology is put forward to prevent rock burst in roadways, and the numerical simulation results show that stress distribution of surrounding rock meets the model of strong-soft-strong (3S) structure, and the moment distribution is reasonable. …”

Mechanical Behavior and Acoustic Emission Characteristics of Sandstone Under Different Cyclic Loading and Unloading Disturbance Rates
Published 2025-01-01“…ABSTRACT The frequency of dynamic disasters is escalating in deep coal mining, with an increasing number of disasters induced by the combined static and dynamic loading. To investigate the mechanical behavior of deep sandstone under mining, cyclic disturbance, uniaxial cyclic loading, and unloading tests with equal amplitude were conducted at four different disturbance rates on the basis of static loading. …”
