摘要
介绍了祁东煤矿沿空掘巷大断面锚网梁索配合工字钢背帮支护情况,优化了沿空巷道支护的参数,保证了巷道的稳定,取得了较好的技术经济效益,为祁东煤矿沿空巷道推广锚网支护奠定了良好基础。
The paper introduced the application of anchor mesh and beam-rope combining with I-beam supporting sides for large section gob-side entry driving in Qidong Colliery,which optimized gob-side entry supporting parameter,ensured roadway stability,achieved better technical and economic benefits and laid a better foundation for bolt support extension in gob-side entry in Qidong Colliery.
