Design of Ground Subsidence Management Scheme for Coal Transportation Special Line

Abstract:

According to the characteristics of subgrade subsidence of coal transportation special line of Huangling Mining Company at K6 680～800, pre-stressed anchor frame beam and perforated pipe grouting method were suggested to be used for the consolidation of subgrade vertical supporting and retaining structure and the improvement of anti-deformation of subgrade. The paper analyzed the force conditions of vertical supporting and retaining structure and introduced the management scheme design.
