Stability Control and Effectiveness Evaluation of Deep Shunts Roadway
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.
