Study on design cross-section with anchor of roadway of longwall CIII-6-1B level +10 Vang Danh coalmine

Abstract

     Based on the results of research on geomechanical conditions of working roof rock mass at roadway level +10 III-6-1B Vang Danh Coal Company - Vinacomin [1], the authors proposed to choose an trapezoidal cross-section and design with anchors at two levels (rock bolt with cable anchors) according to [3]. The method is a new tool to help mining engineers refer to, compare or use in the design of tunnels with anchors, thereby improving the effectiveness of anchoring in underground coal mines.
