Innovative Approach to Monitoring Coal Pillar Deformation and Roof Movement Using 3D Laser Technology

Popis výsledku v původním jazyce

Monitoring of pillar and roadway deformations is one of the most important issues in geotechnical engineering and miningnpractice. The use of 3D laser technology is ideal to monitor strata displacements in underground excavations enabling complexnspatial data capture of the entire space around monitored pillars including all roof and rib deformation which occurs duringnthe pillar excavation. This method based on repeated scans, can monitor the excavation surface movement ranging from a fewnmm to more than 600 mm. The 3D laser scanner was used to monitor the coal mine roadways and pillar stability in roomnand pillar panel trial in the Ostrava-Karvina coal basin (OKD Mines, Czech Republic). The 3D data analysis indicated ribnmovement that ranged from 250 mm to more than 600 mm, a large floor heave that was regularly brushed and practically no roofnmovement of very strong roof strata overlaying the whole panel area. All scanned results compared well to the results fromnthe extensometry and other measuring instruments. The results further indicated that the mined roadway cross sectional areandecreased between approximately 15-25 % during the first 7 months of monitoring and stabilized at 5 % after another 7 months.nFurther monitoring is planned to identify any long term creep in the room and pillar panel.
