Surface and underground subsidence correlation
Underground subsidence survey technique at site where industrial and important surface structures limit underground extraction; survey stations established at surface and in existing roadways at each horizon, at intervals ranging from 21 m at surface to 10 m in deepest horizon; stations consisted of steel pins with 2 in. sq plate welded to top; stations were leveled periodically from bench marks in each seam.
