Product Details
The coal mine roof detachment monitoring system monitors the working resistance of the fully mechanized mining face supports and advance support, and can display and alarm on-site to monitor the displacement and speed of the roof detachment in the excavation and mining tunnels, and provide on-site alarms to monitor the anchor rods or anchor cables of the anchor net tunnel. Load stress monitors the internal stress of surrounding rock or coal mass.
