【摘要】 采空区是引起地表塌陷、恶化矿山开采条件的严重安全隐患,对不明采空区的精细探测技术、治理技术及安全监测装备与预警技术的开发研究,是复杂条件下矿山安全高效开采迫切需要解决的重大课题。以西郝庄矿为工程背景,介绍了采空区地表GPS监测系统及沉降监测方案;通过在地表合理设置若干个监测点,利用所安装的监测系统来监视裂缝区域和地表沉降区域的动态演变过程,并将监测信息发送到监控室;通过布点监测,及时预测地压来临时间,为预警决策和矿山及时撤出处于危险区人员提供依据,实现矿山安全生产,具有一定的推广意义。更多还原

【Abstract】 Goafs as the inescapable cause of ground subsidence and worsened mining conditions are worth much work in the development of precise probing technology,treatment,and safety monitoring equipment and early warning technique,which have been the major subject to be solved in mine with complicated conditions.With Xihaozhuang mine as the engineering setting,the paper introduced the GPS monitoring system and subsidence monitoring scheme of the ground above mined-out areas.With the help of installed monitoring system,several properly designated monitoring points can be used to monitor the dynamic evolution process of the cracking and subsidence areas and the monitoring information can be sent to the control room.Through the monitoring points,and timely forecast for burst time of ground pressure,the control room staff could accordingly make early warning decision and evacuate personnel at risk area,realizing safety production.The process is worth promoting in mines with similar conditions.更多还原
