Thus, different mining methods, different block structural parameter and different drawing way influence the stability of mining system.
因此，不同的采矿方法、不同的采场结构和回采方式，对地下采矿系统的稳定性都有着直接的影响。
To block stoping, mining system design mainly includes design of block parameter, design of pillar's dimension, design of ore drawing sequence.
对于阶段空场法，采矿系统设计主要包括采场结构参数、矿柱大小、回采顺序等。
