Data is presented from a ground deformation monitoring program conducted at a surface coal mine over a two year period. Monitoring focused on the mining of a coal measures sequence on a footwall slope. Mining plans had aimed to isolate a remnant pillar block, 12500 m2 in plan, carrying a 132kV pylon tower and thus to maintain the integrity of a cross-pit power line. Pillar deformation which arose from shear on inclined strata is reviewed and related to the excavation sequence by strike cut and dip cut mining, involving remedial backfill buttressing. The monitoring program was based principally on an array of borehole inclinometers, supported by ground tiltmeter and conventional survey methods. The paper discusses the performance of the monitoring practice and strategy adopted in this mine production environment. |
