摘　　要：针对程潮铁矿高压区的形成及产生的危害,采取崩落支承柱与大量放矿卸压,改变采场结构参数增大分段高度与进路间距,减少上分段回采对下分段支承压力的影响;光面爆破提高掘支质量最大限度地提高围岩的自承能力等综合技术措施,卸掉了高压区破坏性地压,减少了地压活动对回采作业的影响。To cut damage and effect from high - stress zone in stope during mining operation in Chengchao Iron Mine, some test measures such as caving ore pillar, ore drawing for pressure relief, changing structure parameter of stope, use of smooth blasting, improvement of drilling and support etc. were taken and good results were obtained.
