Relationship between hydraulic conductivity and fracture properties estimated from packer tests and borehole data in a fractured granite

Analytical and experimental study of water seepage propagation behavior in the fault

“…The water injection test method in this work is illustrated in Figure 6. Nowadays, the packer test is used to be the usual tool for hydro-geological testing in boreholes (Guo et al, 2003;Hamm et al, 2007;Cheng et al, 2009;Quinn et al, 2011). But it is difficult to install in coal mines sometimes due to the complex conditions, e.g., site conditions in the underground tunnel, construction conditions and geological conditions (Huang et al, 2014).…”

Rock Mass Hydraulic Conductivity Estimated by Two Empirical Models

“…In addition, Gustafson et al, (1991) described that 44 to 61% of fractures in granite are non-conductive based on the field hydrological tests. By performing similar approaches, Hamm et al, (2007) demonstrated that the fracture aperture has stronger relationship to hydraulic conductivity than fracture frequency. They also proposed that the cubic fracture aperture model has close relationship to transmissivity with the highest correlation coefficient of 0.88.…”

Hydraulic conductivity characterization of a karst recharge area using water injection tests and electrical resistivity logging

“…The relationship between hydraulic conductivity and fracture properties such as frequency, length, aperture, specific orientation interconnectivity of the network, filling materials and features of the fracture surface, is complex (Park et al, 2001;Hamm et al, 2007). Consequently, nowadays, more emphasis is being placed on integrated surveys in which two or more complementary investigation methods are combined to obtain an adequate interpretation.…”
