Description
technical field
[0001] The invention belongs to the technical field of roadway surrounding rock control in coal mines, and in particular relates to a roadway surrounding rock deformation monitoring bolt, an online monitoring device and a monitoring method. Background technique
[0002] With the depletion of shallow resources in most of the main coal production areas in my country, coal mining has gradually entered the deep mining stage. Affected by the complex conditions in the deep, the technical difficulty of maintaining deep roadways has increased. The current domestic mainstream support method is Anchor (cable) support. Since the roadway is a hidden project, its safety hazards are not easy to be found, so it is necessary to adopt technical means to monitor the deformation of the surrounding rock of the roadway during the production process. At present, the roof delamination instrument is mainly used in China to monitor the deformation of the surrounding rock of the roadw...
