Gravity Vertical Profiling in the Shaft Mining “Sosnica – Makoszowy”

The main objective of this study was to detect loosened zone in the vicinity of the rock shaft within the accuracy of the method of microgravity. The position of these zones can be one of the causes destabilization of the shaft. Rocks around the shaft undergoes weakening threatens its stability, depending on the degree of reduction in the density of rocks in the vicinity of the shaft. The solution to this problem was carried out by analyzing the results of studies of surface microgravity method and separation density complexes based on the results of gravity vertical profiling (PPGR). This paper presents the results of state farm PPGR.
