Background
Unlike other types of engineering projects, ground mining mountains have very limited control over the site conditions by engineering managers. Even if an underground positioning system and an underground communication system are installed, managers still have difficulty in monitoring the real-time situation of a construction area. In the construction process of the underground operation unit, different operation procedures can generate different vibration signals in the surrounding rocks, so that the condition and the duration of the operation unit can be judged by monitoring the vibration signals of the surrounding rocks in an operation area, and the method is a feasible field management method. Meanwhile, as the underground operation activities are greatly related to the surrounding rock activities, various well accidents are related to the surrounding rock movements. Therefore, the monitoring of the site rock fracture signal can provide a very valuable reference for site safety management. Although many microseismic monitoring systems exist at present, the microseismic monitoring systems are often used for regional safety early warning work and are not tightly combined with field management. In order to ensure the safety of site construction, a large amount of manpower and material resources are often spent by an earth mining mountain unit, and safety supervision personnel are dispatched to carry out site management, so that the effect is not obvious.
After retrieval: chinese patent CN201910388659 discloses a tunnel microseismic monitoring rock fracture event automatic identification method, which can automatically identify and filter rock fracture waves, but can only filter rock fracture signals to make investigation for regional safety evaluation, and is not tightly combined with field management; chinese patent CN201911047307 discloses "an attendance machine and attendance system based on gait recognition", which can record the attendance state of a worker by recognizing gait and is applied to enterprise management, but the system is difficult to be applied to downhole field management.
