| Abstract: | The earth surface subsidence rule in mining coal under special railway line at fully mechanized sub- level caving face 701 of Baojishan mine with finite element method is studied.The laws of the development of the earth surface horizontal and vertical displacement with mining are given.The monitoring results indicate that the cal- culation subsidence is consistent with practical subsidence.The finite element calculation model and parameter is rea- sonable.The calculation result is very important for the normal mining on 701 work face. |
| Keywords: | special railway coal mining surface subsidence monitoring FEM |
