Název v původním jazyce
Verification of stress state monitoring in the surroundings of the roadway ahead of longwall mining based on the results of 3D scanning of roadway deformation, Bogdanka Mine, Poland
Popis výsledku v původním jazyce
For designing precisely the reinforcement of mine tunnels and reinforcing underground structures in general, knowing stress and deformation states in the rock massive (hereinafter also referred to as the “RM”) in the immediate vicinity of these mine works as precisely as possible is absolutely decisive. Stress is usually determined by interpreting deformation processes in the RM. These can be monitored and measured relatively exactly. Tunnels are loaded especially by longwall pressures. In addition, the distribution of stress is also influenced significantly by older mining activities, edges and pillars in the rock cover, or by seams mined through old-workings. All of these factors can influence significantly stress and thus also deformation manifestations in the surroundings of mine works. For the purpose of checking changes in the state of stress in the RM induced by mining, the monitoring of the state of stress in the RM in connection with mining seam 385 using longwall G6 in the black coal mine of LW Bogdanka in Poland was designed and carried out. The purpose of the monitoring carried out was to verify changes in the stress tensor during the mining process. For the purpose of verifying the monitoring of stress, the survey of the state of the tunnels was carried out using a pulse 3D scanner in the place of the geotechnical station (GS). The purpose was to capture deformation changes ahead of the advancing longwall face in the surroundings of the GS.
