| 英文摘要 | In order to study permeability characteristics of low-strength coal under higher confining pressure, complete stress-strain permeability characteristics tests on 15# coal of Shanxi Province Qinshui Basin are conducted. Research shows that 15# coal manifests obvious plastic under 6MPa confining pressure whose uniaxial compressive strength is 7.43MPa; The saturated specimen' permeability reduces provisionally during initial compression as the native fractures are closed; With the specimen compressed continuingly, new fractures appear and those fractures connect, then the permeability rapidly increase; But while the soft coal enters into plastic-flow state, because that the specimen becomes more homogeneous and fractures have closed, the permeability greatly reduces lower then the initial value. Research result has important guiding significance for reasonable retaining waterproof pillar in deep mining. |
