Abstract

By using the finite element software ABAQUS, the paper carries out numerical simulation analysis on influence of new coal lane tunneling along the groove disturbing the original high pumping Lane in a deep mine 1112 working face in Huainan. This article analyzes two tunnels in different distance with the new roadway excavation cause position change as well as an increase in the maximum stress and displacement of the original high pumping Lane in deep mine. In this essay, we explore the influence of new roadway excavation to original roadway stability, and study the deep adjacent tunnel excavation disturbance effect to the original roadway stress and strain change. The results show that: the reasonable distance between shallow tunnels is not applicable to deep condition. Meanwhile, the roadway excavation disturbance effect between adjacent tunnels is significantly in deep mine. In addition, the original roadway need to add new support measures on the basis of the existing supporting structure to ensure its normal use.
