Solution after the stress balance in the empty area is broken

> #>Once a dangerous accident occurs in a mine, the resulting collapse or subsidence of the goaf will be difficult to predict. Therefore, early prevention and technical monitoring of the goaf are particularly important. Risks and ground damage will occur in the goaf. The root cause of phenomena such as settlement, deformation, landslides, and dam instability is that the balance of the original stress system is broken, and the rock mass re-finds the stress balance. To put it simply, instability occurs only when the stress balance is broken, and then displacement occurs. The change in stress must occur before the result of displacement occurs. The change in stress is the cause and the change in displacement is the effect. Therefore, the stress changes before instability can be used to monitor the stability of the rock mass. For slope stability monitoring, drilling can be carried out from the surface into the slope. The bottom of the hole must be a certain distance beyond the rupture sliding surface. The stress of the steel strand must change before a landslide.
: > #>In response to the problem of goaf areas, the Weihai Jinghe Mining Star Mine goaf stability fully automated network monitoring system monitors the stress of the surrounding rocks and supporting structures in the goaf. Force, strain, and displacement signals are used to conduct comprehensive monitoring and integrated analysis of multiple parameters to maximize the complementarity of various monitoring indicators, thereby significantly reducing the cost of the monitoring system, improving the accuracy of disaster monitoring, and realizing the procurement Real-time monitoring and early warning of airspace disasters.
