中文摘要：

直观可靠地预测预报采空区地压活动,能为矿山正常采矿作业及管理决策提供有力的保证。以正旺铁矿为研究对象,通过采空区地压活动的时空分布掌握地压活动规律,初步判定采空区的稳定性,再结合影响采空区稳定性的其他因素建立采空区稳定性预警等级,综合评价采空区稳定性。结果表明：通过对地压活动的时空分析能较好地掌握井下地压活动规律,考虑多因素的采空区稳定性预警等级能为矿区正常采矿作业提供更好的保证。

英文摘要：

The intuitive and reliable prediction of the ground pressure activities in goaf can provide a powerful guarantee for normal mining operation and decision-making for management in mines.With Zhengwang Iron Mine as a research object,space-time distribution of the ground pressure activities in the goaf can indicate the regularity of ground pressure activities with the preliminary judgement of stability of the goaf and combined with other factors influencing stability of the goaf to establish the early warning level of the goaf stability for comprehensively evaluating stability of the goaf.Results show that the regularity of ground pressure activities can be known by analyzing space-time distribution of the ground pressure activities and the early warning level of the goaf stability considering multiple factors can provide a better guarantee for normal mining operation.
