With the implementation of significant national strategies and rapid socioeconomic
development, many ultra-long deep tunnels are being constructed in the Qinghai–Tibet …

The instability control of deep mining roadway is currently dominated by ejection and
grouting, as well as floor support, which contradicts the economic and excavation efficiency …

Mining roadways in soft rock are seriously deformed and damaged, which affects the normal
production of the mine. Based on the **n'Shang'Hai No. 1 Coal Mine project, a true 3D …

Safe and efficient coal mining has always been restrained in high-stress roadways due to
their highly rheological property and large-scale deformation, which are key technical …

In order to solve the problems related to deformations, failures, and difficulties in support
controls of deep coal mine roadways, the typical failure forms and characteristics of deep …

This paper proposes a digital image processing-based detection algorithm for cross joint
traces of coal roadway heading face. Initially, the acquired images were preprocessed, ie …

In the confinement of traditional supports, reinforced supports are often used to control the
deformation of roadways constructed in soft rock. Due to the failure to weaken the factors …

The fractured rocks distributed near the structural surface of coal roadway heading face can
easily cause water or air conduits, ultimately resulting in accidents that threaten production …

Anchoring support using bolts and cables works together with rock masses to form an
integrated anchoring system and jointly resists the energy released by dynamic disasters …

The deformation of surrounding rock in the withdrawal roadways of fully mechanized
working faces is a critical factor affecting the safe and efficient withdrawal of mining …
