济源煤矿采空塌陷区治理注浆施工技术研究

A Study of Grouting Construction Technology for Reclamation of Coal Mine Mined-out and Subsidence Area in Jiyuan

河南省济源市克井镇北煤矿区,经过20多年的开采,地质环境破坏严重,造成的主要环境地质问题有采空塌陷、地裂缝等。随着煤矿采空区地质环境条件的不断恶化,引发的环境地质问题日益突出,因采空塌陷造成当地居民房屋开裂,地面出现裂缝,给当地人民群众的生产生活造成严重的影响。就该煤矿开采引发的环境地质问题进行了剖析,提出了采用注浆施工技术对采空塌陷区进行治理的方法。

After more than 20 years＇ mining, the geological environment of north coal mining area in Kejing Town, Jiyuan City, He＇nan province has been destructed seriously, and it includes mined - out and subsidence, ground fissure and so on. Along with the continuous deterioration of geological environmental condition in the coal mined -out area, the environmental geological problems are prominent day by day, and it results in crack of the local resident house dehiscence and fissure of the ground surface, these influence on local people＇s production life seriously. This article analyzes the environmental geological problems caused by coal mining, proposes a method of grouting construction technology for reclamation of coal mine mined - out and subsidence area.
