摘要
Abstract
Aiming surrounding rock deformation of the wind tunnel during mining face extraction in changping mineⅢ2309 mingface. Through investigation and observation the support form, surrounding rock deformation and bolt breaking situation, analysis reasons of surrounding rock deformation. This paper proposes the supporting advice and program, and observing the deformation of surrounding rock after supplement support. This paper educes that should supplement support above 100m lead mining face, and supporting member should be match with cable.关键词
