摘　　要：地压监测是研究矿山采空区力学状态和地压活动规律的科学手段。为了防止七角井铁矿采空区发生塌陷事故,提出了采用围岩应力变形和顶板位移相结合的地压监测系统方案,并对实际监测结果进行围岩应力应变及顶板位移变化分析。结果表明,采空区整体处于相对稳定状态,短期内不会发生大范围冒落;地压监测系统的建立及实施揭示了采空区围岩、顶板的矿山力学状态及地压活动规律,对促进七角井铁矿安全生产和提高矿山安全生产管理水平等具有重要的意义。The monitoring of ground pressure is a scientific method to study the mechanical state and the law of ground pressure in the mine goal. In order to prevent the Qijiaojing iron mine goaf Collapse, based on surrounding rock stress and deformation of roof displacement combination, the ground pressure monitoring system scheme was put forward. According to the actual monitoring results, the stress and strain of the surrounding rock are analyzed. The results show that the mine goal is in a relatively stable state, and the large scale caving will not occur in the short term. The establishment and implementation of the ground pressure monitoring system reveal the rock mechanics and the law of ground pressure, it is of great significance to promote the safe production of iron ore mine and improve the management level of mine safety production in the Qijiaojing iron mine.
