摘要：
One development trend of high intensity mining is to set a certain coal pillar in two adjacent stoping roadways of adjacent working faces at the same time, and the long-term stability of surrounding rocks of the two roadways is very important. In this paper, the deformation and failure characteristics of roadway surrounding rock are studied base on field borehole imaging. Numerical simulation has been used to study the mining-induced zoning differentiation characteristics of surrounding rock stress and deformation failure of double roadway layout transport roadway under the effect of mining. The differential control technology for double roadways based on side anchor cable and bottom corner anchor bolt has been put forward, and working face 13406in Wantugou coalmine have been selected as the test site to carry out field industrial test, which verifies the rationality of roadway control technology and parameter design. © 2021, Editorial Board of Journal of Mining & Safety Engineering.
