Application Research of Grouting Anchor Cable in Ad-Vanced Support of Fully Mechanized Mining Face
In order to improve the effective control of the surround-ing rock of the mining roadway in the fully mechanized mining face of Huozhou Coal Electric Mugua Mine,it is proposed to ap-ply grouting anchor cables to the advanced support of the mining roadway.The layout scheme and on-site application effect of the grouting anchor cables are analyzed,taking the auxiliary transpor-tation channel of the 10-206 working face of the mine as the re-search object.After on-site application,the deformation of the sur-rounding rock in the advanced support section of the auxiliary transportation channel in the 10-206 working face was relatively small,and the roof remained stable.At the same time,after cancel-ing the advanced single pillar,the labor intensity of the staff was significantly reduced,and the transportation and ventilation sec-tion of the roadway was significantly increased,creating relatively good conditions for efficient coal mining in the mining face.At the same time,it also provides reference and reference for the applica-tion of grouting anchor cables in similar geological conditions of the mine.
