Abstract: The Mining engineering in this deposit belongs to deep mining.Selection of mining methods plays an important role in ground pressure control.Based on geological analysis in this area, combining with the actual production in Sanshandao Gold Mine, Jiaojia Gold Mine and other similar mines, the upward drift stoping with backfill is adopted, according to the relevant provisions of the local safety supervision departments.Through the mechanical analysis and the numerical simulation method, the influential factors on the drift stoping are analyzed from the mining structure parameters, filling materials and filling operation, then some suggestions are put forward.

Key words: Mining method, Filling, Mechanical analysis, Numerical simulation
