摘要
为解决基于传统支护参数对深部顺槽巷道支护面临的片帮、顶板下沉及底鼓等问题,在对3号煤层回采巷道地质条件和支护现状进行分析的基础上,基于锚网索耦合理论对支护参数进行优化实现支护手段与巷道围岩的二次耦合,同时在现场布置4个观测点对支护效果进行综合监测,并综合分析其社会效益.
Abstract
In order to solve the problems of ganging,roof sinking and bottom bulging faced by the support of the roadway in the deeper part of the roadway based on the traditional support parameters,based on the analysis of the geological conditions of the No.3 coal seam back to the mining roadway and the current situation of the support,we optimize the support parameters based on the theory of anchorage coupling to achieve the second coupling of the means of support and the roadway perimeter rock,and meanwhile,we set up four observation points on the site to monitor the support effect and analyze its social benefits.The social benefits are analysed.
