摘要
由于大同煤矿集团公司煤炭开采已逐步转入深部和近距离煤层群,传统的支护方式已不能有效地管理顶板,为此尝试了锚杆、锚索联合支护新技术的应用,通过现场实践和技术经济比较,表明该技术是可行的。
Because of that the coal mining of Datong Coal Mine Group Company has gradually come down to the deep parts and near coal bed groups, traditional support methods can't be used to effectively manage the roof. Therefore the trail application of the anchor rob and anchor rope combined support technique has been made, and the field practice and tech-economic comparison show that this new technique is practicable.
