| Abstract: | Based on analyzing the geological characteristics of thick loose layer with confined water,the load key strata position is judged,the model of loading key strata is established.By the method of numerical simulation,the models of confined water and excluding confined water are established,the influence of thick loose layer with confined water on the working face support pressure is analyzed.It has important the theory significance and the practice value for preventing the accident of working surface pressure frame. |
| Keywords: | loose aquifer confined water the loading key strata numerical simulation |
