Abstract

Abstract

Combining the practices from soft rock roadway supporting in Wadong Coal Mine, with analysis on the physical mechanic properties of the main coal-bearing layers and the engineering geological characteristics of the soft rocks, the authors pointed out that along with the increasing of exploitation depth, stress and deformation of adjacent rock of roadway obviously increased, which was the main factors influencing the selection of roadway layer and related supporting patterns. Therefore, an associated supporting pattern accord with the engineering geological characteristics of the adjacent rock should be selected.
- soft rock roadway,
- supporting method,
- Wadong coal mine,
- Huangxian coalfield
