Research on Deformation Control Measures of Surrounding Rock in Soft Rock Tunnel
IOP Conference Series: Earth and Environmental Science, 2021 Abstract In order to study the control measures of soft rock tunnel surrounding rock deformation, based on the restraint effect of shotcrete anchor support on it, a support model was constructed, and numerical simulation was used to compare and analyze the restraint effects of different bolts controlling the surrounding rock deformation.

Thermal response of jointed rock masses inferred from infrared thermographic surveying (Acuto test-site, Italy) [PDF]
, 2018 The Mediterranean region is affected by considerable daily and seasonal temperature variations due to intense solar radiation. In mid-seasons, thermal excursions can exceed tens of degrees thus influencing the long-term behaviour of jointed rock masses ...

Controlling Effects of Surrounding Rock to Coal Seam Gas Occurrence
Open Journal of Geology, 2013 Surrounding rock of coal seam was one of the important factors to gas occurrence. The coal seam gas occurrence was studied by the index of roof strata thickness or sand content rate; we found that there were certain shortcomings. In order to reasonably evaluate the influence of coal seam surrounding rock on gas occurrence in Panji mining area, we ...
