The Research on the Stability of the Foundation and Grouting Treatment Effect under the Process of Surface Structures in Old Mined-Out Areas
Firstly, it simulates different depth at nanmaquan and civil mines respectively with the software of MIDAS to carry out in phases; secondly, it discusses the rule of vertical settlement surrounding rock and cover rock in the mined-out areas; lastly, it analyzes furtherly the rules of changes with the method of adding different load in order to research the stability of the foundation under load in the old mined-out areas. The filling grouting of falling belt and cracks belt have been explored and analyzed on the basis of a series of different methods such as total filling grouting, part decreasing stride, separating rock and board, and independent rooting, and so on. Afterwards, it applies XBHV-10-foot steel settlement instruments to measure on the scene and analyze the effect. Minded-out areas reached the desired treatment effect.
