摘　　要：深入研究了三维应力作用下裂缝中气体渗流规律,得出了裂缝剪切变形同法向变形一样,对气体裂缝渗流规律有显著影响的结论,并给出了气体单一裂缝渗透系数的解析式。实验证明该式更加符合实际情况。The gas seepage law in a single fracture under 3D stress is studied and the following conclusions have been made: (1) the tangent deformation has the same effect as normal deformation on fracture seepage law, and (2) gas seepage law is different from water seepage law. Moreover, an analytic formula of gas seepage law in a single fracture is presented. Experimental data are analyzed by using the theory above and the results show such theory can reasonably describe the gas seepage law in a single fracture under 3D stresses.
