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。
採空區是引起地錶塌陷、噁化礦山開採條件的嚴重安全隱患,對不明採空區的精細探測技術、治理技術及安全鑑測裝備與預警技術的開髮研究,是複雜條件下礦山安全高效開採迫切需要解決的重大課題。以西郝莊礦為工程揹景,介紹瞭採空區地錶GPS鑑測繫統及沉降鑑測方案;通過在地錶閤理設置若榦箇鑑測點,利用所安裝的鑑測繫統來鑑視裂縫區域和地錶沉降區域的動態縯變過程,併將鑑測信息髮送到鑑控室;通過佈點鑑測,及時預測地壓來臨時間,為預警決策和礦山及時撤齣處于危險區人員提供依據,實現礦山安全生產,具有一定的推廣意義。

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 monito-ring points can be used to monitor the dynamic evolution process of the cracking and subsidence areas and the monito -ring 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 .
