摘要
通过对程潮铁矿 - 2 2 0～ - 2 90m中段的 5个分段水平中地质构造较复杂的第 5～ 10采区地压显现情况的调查 ,结合程潮铁矿矿岩的稳定性分级 ,对采场地压分布及活动情况进行了分析 ,并就其控制措施进行了探讨 ,对后期开采控制地压活动有一定的指导作用。
Based on the investigation of the activity of the ground pressure in No.5～ 10 mining areas that have complex geological structure in 5 sublevels within-220～ -290 m middle section at Chengchao Iron Mine and in view of the stability classificatoin of the orerock of the mine,analysis is made of the distribution and activity of the stope ground pressure and its control measures are discussed,which is of certain guidance significance to the control of the ground pressure in the future mining.
