安家岭煤矿露井联采区沉陷状况调查及防治

Survey and Control Measures about Sink Status in Open-underground Combine Mining of Anjialing

以平朔安家岭煤矿露井联采区为例,通过全球定位系统(GPS)和人工调查相结合的方法,针对露井联采区排土场——人工堆置地貌的平台、边坡以及采空沉陷进行实地调查,对形成的沉陷和受损特征进行统计分析,发现下方煤层已开采完和正在开采的样带沉陷较为严重,而尚未开采的沉陷较轻,但易引发小型滑坡。最后,根据实际情况提出防治对策及建议。

Taking open-underground combine mining of Anjialing coalmine as the example,the global positioning system combined with artificial survey was used to investigate the status of the mined-out area.Statistical analysis was carried out on the subsidence formed and characteristics damaged.Transects about mined and mining subsided severely,unmined area subsided slightly but was prone to landslide.Finally,control measures and recommendations were proposed.
