Abstract
The application of hollow grouting anchor cable in soft coal seam was introduced in this paper, soft coal rock mass macro physical and mechanical properties, anchor cable and bolt arrangement, size selection, grouting pressure, grouting quantity, etc. speciifc parameters were analyzed, the improved hollow grouting anchor reinforcement and improvement methods was found, contrasted previous grouting anchor cable and U29 shed, it showed that new hollow grouting anchor used can improve the roadway forming effect significantly and the construction progress, also greatly reduce labor intensity and the cost of expenditure.关键词
