锚网索联合支护在大断面托顶煤切眼中的应用
|
摘要
在介绍锚网索联合支护机理的基础上,综合分析综放大断面切眼围岩破坏的机理及其主要特征,并阐述了其支护重点。同时结合锚网索联合支护在龙固矿井首采1301N工作面切眼支护中的成功实践,论证了锚网索联合支护在综放大断面切眼支护中应用的可靠性,为同等条件下的应用推广提供借鉴。
Based on the introduction of the bolt-steel mesh-anchor combined support mechanism,the paper had a comprehensive analysis on the surrounding coal failure mechanism and the main features of the large cross section open-off cut for the fully mechanized top coal caving mining face and introduced the support key points.In combination with the successful practices of the bolt-steel mesh-anchor combined support applied to the open-off cut of the first No.1301N coal mining face in Longgu Mine,the paper discussed and confirmed the reliability of the bolt-steel mesh-anchor combined support applied to the support of the large cross section open-off cut for the fully mechanized top coal caving mining face,which could provide the references to the application promotion under the same conditions.
