| Abstract: | According to the existing problems of the sublevel carity working being employed at Dongchuan Mianshan, high dilution and ore-loss, low efficiency, unsafety. This paper proves the characteristics of continous sublevel cavity working and arranges the physical model experiment by using the orthogonal experimental design method of drawing simulation. By analysizing the acquired representative data and experimental results, then we prefer the recommended value of reasonable stope structural parameters which should be adopted by industrial experimental design and production, and the predicted values of recovery and dilution. These results will play a initiative guiding role in the design and production of new mining method of this mine. |
