Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]

, 2010
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

Loose circle and rock mass strength tests of extremely thin layered surrounding rock in large deformation tunnels

Scientific Reports
Abstract The scope of the surrounding rock loosening and its mechanical properties can significantly affect the analysis of the excavation loosening range, stress-strain state partitioning, and surrounding rock mass stability. Investigating the mechanical properties and failure modes of the surrounding rock mass, optimizing the support design ...

Stability analysis and control countermeasures of surrounding rock of gob-side entry formed by roof-cutting in inclined coal seams

Energy Exploration & Exploitation
The stability of the surrounding rock in the inclined coal seam stope is crucial for the safety of the gob-side entry. In this article, we systematically analyze the surrounding rock stability of the gob-side entry formed by roof-cutting (GEFR) in an ...
