Fore Sudetic Monocline - Opis:
- The paper presents the review of methods for determining hydrogeological properties of rock mass in the place of mine shaft location. The largest Polish copper ore deposit is located in the Fore-Sudetic Monocline. It is the Kupferschiefer-type deposit occurring at a depth of 400 to 1200 metres. During the last 60 years the deposit was opened with 30 mine shafts, and the 31st shaft is currently being sunk. The methods of hydrogeological tests in boreholes as well as the methods of estimation of hydrogeological parameters and prediction of water inflow into the sinking mine shaft have evolved through the years. In the 1960s, the most popularfield test was the well bailing/infiltration test, and the most popular methods ofparameters estimation and inflow prognosis were analytical equations and analytical methods of water inflow forecasting. These methods provide very uncertain results. The best and reliable results of predicted water inflows are derived from methods based on long-term pumping tests and numerical modelling. These methods were used in the IMore project which concerns possibilities of dewatering of the Bundsandstein aquiferfor a mine shaft sinking purpose.
