Therefore, the above-mentioned roadside supports have the disadvantages of supporting resistance, and shrinkage cannot adapt to the large deformation of surrounding rock of GER nor effectively isolate the goaf, making it difficult to achieve high mechanization. Consequently, it is necessary to study ...
(3) Aiming at the specific engineering geological conditions of the west-wing main track roadway and considering the advantages and disadvantages of the main roadway's original support scheme, a set of targeted "shielding-filling-grouting" integrated col- laborative control technology system was ...
Such methods require the manual arrangement of monitoring tools, which have the disadvantages of human interference, low automation, and long time consumption [10,12]. In addition, some high degrees of automation monitoring methods, such as the roof abscission layer instrument measuring method, ...
