中文摘要：

采用MTS815．02型岩石力学伺服试验系统，对桃园煤矿10煤底板的岩样进行全应力一应变渗透试验，得到岩样裂隙在闭合、萌生、扩展过程中的渗透特性。通过对不同非承压状态下裂隙岩石的渗透性能的研究，为采场底板隔水性能的研究提供重要参数。数值研究表明，在工作面的不断推进过程中，底板将处于压缩一膨胀一压缩的状态，而在压缩与膨胀变形过渡区，底板最容易出现剪切破坏，最终形成导水通道。基于上述研究，对桃园煤矿10煤底板隔水性能进行评价，并提出了防治实践。研究结果对于制定裂隙岩体的防治水措施，防止采动过程中突水事故的发生具有一定的指导意义。

英文摘要：

The permeability test on complete stress-strain of the rock sample in the floor of Tao Yuan Coalseam 10 was conducted by using MTS815.2 Rock Mechanics System. Studied the seepage properties of rock sample on different unconfined state, including the characteristics of fracture closure, initiation and extension, some important parameters were provided for the research of water isolating in mining floor. The simulation results showed that the floor had been in a state of compression-expansion-compression in the process of face advance. In the transition zone of deformation between compression and expansion state ,failure occurred easily when the floor had a shear plastic deformation. The evaluation of water isolating and the prevention practice were based on the research. The study had certain significance to water-inrush prevention while mining.
