Abstract

In order to reduce the serious roadway deformation during mining, the support scheme is optimized. Based on the actual geological data of mining roadway 11070, the plastic zone morphology, stress field and displacement distribution of roadway under different support schemes are analyzed by numerical simulation. The results show that scheme 1 has better supporting effect and higher roadway stability, which provides a reference for the same type of roadway support.
