Numerical Simulation of Lag Water-bursting for f0 Fault in Fangezhuang Coal Mine

摘要：

The F0 scale fault of the Fangezhuang coal mine, Kailuan coal group, threads the whole mine field. On the base of the creep mechanics examination of the faults material, we get the data with different condition. With the help of the numeric simulation software Flac 3D, we get the data of the influence of mining activity to the faults under different time, after the flow-mechanical interaction simulation and seepage creep calculation. The simulation result depict the basic data very well ,such as the pressure waters influence to the overlaying rock and the faults, the mining activity influence to the floor Strata, the size and range of the faults under the mining activity, and the time-effect of the influence of the pressure water. And all of these data provide the credible basic data to the safety of the coal production.
