Research and application of prevent ground surface settlement technology based on frame construction theory
Abstract：Based on the analysis mining under buildings technology status of domestic and foreign,four key points that prevent surface subsidence disasters in the process of mining under buildings were given,and four conditions that gob roof control technology should have,prevent ground surface settlement technology based on frame construction theory was proposed,and it＇s applicable conditions and main technical parameters＇ process of determining were given.The technology has the advantages of construction is easy,work load is small,cost is low,recovery rate is high,the technology not only make roof point of application uniform,benefit to keep roof stable and effectively prevent ground surface settlement,but also can provid time and space for gangue treatment underground after frame structure formation.The study was successfully applied to the scene.
