The geological conditions of Jiaojia Gold Mine are introduced, the types of engineering rock mass are classified and the methods of stope support are evaluated.

介绍了焦家金矿床的赋存地质条件，划分了工程岩体类型，介绍评价了矿山近年来应用的支护方法。

In open stopes the ground above the stope will support its own weight. So the stope is shaped like a series of rooms divided by walls or supported by pillars of ore.

空场回采工作面利用采场上方的岩层支撑自身的重量，所以采场被切割成一系列的由矿壁分隔或用矿柱支撑的峒室。

Finally, support control measures were taken to ensure the stope stability.

最后，提出了控制采场群稳定性支护对策。
