COMPARISON OF BAL'S AND KNOTHE'S METHOD OF CALCULATING SURFACE MOVEMENTS DUE TO UNDERGROUND MINING

DISCUSSED ARE TWO PREVIOUSLY PROPOSED THEORIES WHICH PROVIDE A MEANS OF ESTIMATING THE CONTRIBUTION TO TOTAL HORIZONTAL AND VERTICAL SURFACE MOVEMENT OF EXCAVATION AT SOME POINT BENEATH THE SURFACE. INFLUENCE CHART METHODS ARE ILLUSTRATED FOR HANDLING THE IRREGULAR ZONES ENCOUNTERED IN NORMAL MINING OPERATIONS. PREDICTIONS ARE COMPARED TO ACTUAL MEASUREMENTS IN SEVERAL LOCATIONS. GENERALLY VERTICAL MOVEMENTS (SUBSIDENCE) WERE MUCH CLOSER TO PREDICTIONS THAN HORIZONTAL MOVEMENTS. /ARTICLE/
