Abstract

Aiming at the special situation of high level tunnel under the in fluence of mining in Xieqiao coal mine 21116 working face,the theoretical analysis,numerical simulation and field measurement is taken to analyze it.And it reveals the overlying strata movement rule and mechanism of high level tunnel under the in fluence of mining.The results show that the high level east wing orbit large tunnel ids located in bending subsidence belt.With the working face promoting,the movement of overlying strata is a process of forward and upward extension.Controlled by underlying working face mining disturbance again and again,the surrounding rock deformation of high level tunnel is a process of dynamic evolution tension and compression deformation.According to stochastic medium theory,we are carried out on the movement of the overlying rock mass theory parsing.Numerical calculation shows that two parts of the working face displacement form upper and lower respectively showed shape of ‘vertical half elliptical’ and ‘lateral half elliptical’.And a new method is proposed to monitoring the sink of roadway floor that is drilling from earth surface to roadway.This supervise method will provide a new research direction for study of overburden strata movement.In view of the phenomenon of local deformation and failure of roadway,some reinforcement measures must be used to meet the needs of the coal mine safety production.
