大同、朔南煤田地面沉降监测概述

Compendium of Monitoring Land Subsidence in Datong and Shuonan Coalfield

大同煤田因煤炭资源丰富而闻名,长时间开采产生了巨大的副作用:地裂缝、地面沉降、地面塌陷等地质灾害在大同、朔州两市时有发生。大同市地下沉降区的总面积约810 km2,朔州市地下沉降区的总面积约590 km2,对该地区内各种基础设施产生严重威胁。文中针对上述问题开展系统、深入的研究工作,利用精密水准测量,GPS,InSAR,边坡雷达等多种技术手段对矿区进行地面沉降监测,根据不同的需求逐步丰富和完善大同、朔南煤田地面沉降监测技术手段和监测水平,构建"集中管理、准确预报、功能完善"的地面沉降监测系统。

Datong coalfield is famous for its rich coal resources.But long time mining causes the geological disasters,for example ground fissures,ground subsidence,ground collapse and other geological disasters in Datong and Shuozhou at times.The subsidence area in Datong is a total area of about 810 km2,and the subsidence area in Shuozhou is a total area of about 590 km2.It has a serious threat to the area of infrastructure.In the paper,the author carries out the system and in- depth research according to the above problem,monitors land subsidence of mining area using precise leveling,GPS,InSAR,slope radar and other technical means.The author gradually enriches and perfects the ground subsidence of Datong and Shuonan coal field monitoring technology and the monitoring level according to the different demand and builds the land subsidence monitoring system based on 'centralized management,accurate prediction and functional maturation
