Cross-borehole flow analysis to characterize fracture connections in the Melechov Granite, Bohemian-Moravian Highland, Czech Republic

Popis výsledku v původním jazyce

Application of the cross-borehole ?ow method, in which short pumping cycles in one borehole are used to induce time-transient ?ow in another borehole, demonstrated that a simple hydraulic model can characterize the fracture connections in the bedrock mass between the two boreholes. The analysis determines the properties of fracture connections rather than those of individual fractures intersecting a single borehole; the model contains a limited number of adjustable parameters so that any correlation between measured and simulated ?ow test data is signi?cant. The test was conducted in two 200-m deep boreholes spaced 21m apart in the Melechov Granite in the Bohemian-Moravian Highland, Czech Republic. Transient ?ow was measured at depth stations between the identi?ed transmissive fractures in one of the boreholes during short-term pumping and recovery periods in the other borehole. Simulated ?ows, based on simple model geometries, closely matched the measured ?ows. The relative transmissi
