华北平原区煤矿采空塌陷精细化监测技术方法研究——以永城某煤矿山为例

STUDY ON FINE MONITORING TECHNIQUE AND METHOD OF COAL MINE GOAF COLLAPSE IN NORTH CHINA PLAIN——TAKE A COAL MINE IN YONGCHENG AS AN EXAMPLE

目前塌陷区监测方法有多种,而单一监测方法无法满足多元化数据的需要,以华北平原区永城某矿山地面塌陷监测为例,结合该地区的地质环境条件,采用多种监测技术方法系统对某煤矿山进行精细化监测,即采用常规的水准测量方法监测重点地段(小区域),采用GPS连续运行参考站实时地监测重点采面,采用D-INSAR技术监测全区,从而获得矿区大范围、小区域、实时采面的多目标空间监测数据,为管理部门和矿山企业做好应对策略和风险管控提供了数据支撑,也为同类矿山开展地面塌陷监测工作提供了参考依据。

At present,there are many monitoring methods for subsidence areas,however,a single monitoring method cannot meet the needs of diversified data.Taking ground collapse monitoring of a mine in Yongcheng,North China Plain as an example,Combined with the geological conditions of the area,a variety of monitoring techniques and methods are adopted to carry out fine monitoring of a coal mine.That is to use conventional leveling methods to monitor key areas(small areas),real-time monitoring of key mining areas by GPS continuous operation reference station,Using D-INSAR technology to monitor the whole area.In this way,multi-objective spatial monitoring data of large range,small area and realtime mining face can be obtained.,It provides data support for management departments and mining enterprises in coping strategies and risk management and control,it also provides a reference for similar mines to carry out ground surface collapse monitoring.
