Stability Analysis of Jinghua Gypsum Mine Golf in Jingmen City

According to golf’s distribution and occurrence situation of Jinghua Gypsum Mine circumstances in Jingmen city, The golf is divided into general golf, filling golf, then the stability of column and covering layer of the two kinds of golf are analysed. It is shown that: For the general golf, A large range of column is stable within a relatively short period of time in the process of underground mining. it will be unstable for local small column because of it was bore weight of overlying strata. After the column was soaked, its strength will be greatly reduced, and the long term stability of column will not be guarantee. Complementary, the covering layer is basically critical stable state; For the filling golf, A large range of column is stable, and the covering layer is also basically critical stable state. It can promote the control of mining disaster and the protection of ecological environment and similar engineering with a high theoretical and practical value.
