The Governance Control Technical Analysis Of The Taizhongyin Railway Ningdong Gob

With coal production and consumption, the status of the coal resources as China’s first energy will not change. But after mined solid deposit mining underground mined-out area, it is easy to lead instability of surrounding rock, thus produce displacement, cracking, crushing collapse. Based on this situation, This article research Tai Zhongyin railway engineering which involves the mined-out area of governance. The governance effects not only from the construction process control, and at the end of the construction, through the settlement, the drilling and physical detection methods, down goaf management of high-speed railway is completed to assess the quality of the analysis, to determine its governance effect.This article main research content is as follows:(1) Mainly through the goaf detection method for Tai Zhongyin goaf detection, and put forward corresponding Suggestions; Through stability evaluation criteria and goaf types and hierarchies of Ningdong stability of mined-out area are analyzed, and principles of management are put forward.(2) Through the choice of goaf management technology, grouting construction technology and equipment as research, concluded that the construction technology of goaf grouting and special construction technology, and puts forward measures.(3) By field drilling core statistics, experimental research, integrated geophysical test data combined with inspection standard, analyze the testing results of seismic wave velocity and shear wave velocity value, and determine the grouting effect.
