摘　　要：单一的地压监测尺度已经不能满足矿柱回采过程中对不同尺度岩体安全监测的需求,针对该问题提出了"宏观与微观结合,整体与局部协同"的"最优化"原则,采用微震、应力、应变、位移等不同监测尺度的地压监测技术对某磷矿试验盘区矿柱回采过程中的地压活动进行监测,并指导矿山安全回采矿柱,取得了良好的效果。The single ground pressure monitoring scale can＇t meet the needs of safety monitoring for different scales of rock mass during the process of ore pillar stoping. The ＂optimization＂ principle that ＂macro and micro combination, whole and local coordination＂ is proposed to solve the problem in this paper. Different scales of ground pressure monitoring technologies, such as microseismic, stress, strain and displacement, are used to monitor the ground pressure activities of a phosphate ore test panel during the process of ore pillar stoping. It is utilized to guide the mine stoping ore pillar safely, which has achieved a good result.
