Deformation properties and control models of surrounding rock in deep mines with complicated geological conditions

摘要

The supporting technology of roadway in deep mine with complicated geological conditions is discussed. According to the complicated geological conditions in deep mine at Yuandian Mine, supporting effects of roadway based on existing supporting programs are monitored on-site. The deformation behavior of roadway is obtained and the causes of instability of surrounding rock are analyzed. Supporting principles and control model are proposed pertinently, providing reference for further decision-making of supporting programs in roadway.
