The Method and Application of Rapid Extension of Advanced Reserved Support in Fully Mechanized Mining Face
ZHAO Xin
Abstract：The production conditions of coal mines are extremely complex.When arranging the coal mining working face,the shape of the working face may be affected by various factors such as geological structure,goaf of old tunnels,boundaries,etc.When the working face cannot be arranged according to the design,it will cause significant problems for later mining and installation of the working face.Based on this reason,the purpose of researching advanced reserved supports to ensure rapid extension during the mining process of the working face and avoid frequent extension of supports during the advancement process,which has a significant impact on the mining process of the working face.Through advanced planning for the installation of 15232 working face and scientific organization of reserved supports,convenient conditions have been laid for later mining,while exploring the experience of reserved supports in similar working faces.After on-site actual effect testing,the basic work of extending the support in advance before mining in irregular coal mining working faces has been solved,effectively avoiding hidden dangers and improving work efficiency in terms of safety management and production organization.Therefore,in the actual production process,it is a practical and feasible way to minimize the workload caused by the extension of the working face support.
