| 摘 要： | 淮南矿业集团潘一矿2141(3)工作面地质条件复杂,传统单一的棚式支护难以保证切眼刷面后的安全使用,且单一的锚网索支护技术在局部地段无法施工.为此,提出了工字钢、锚网索加挑棚联合支护技术.该技术的应用解决了2141(3)工作面回撤通道支护困难问题,确保了液压支架的快速安全回撤.

| Abstract: | The geological conditions of 2141(3)working face is very complex in Panyi Coal Mine of Huainan Mining Group.The traditional single shield supporting could not ensure the safe usage after enlarging open-off cut,and the single bolting with wire mesh and cable anchor technology could not be used in local district.Combined supporting technology,including joist steel,bolting with wire mesh and cable anchor,and canopies,was used to solve supporting problem.With the application of combined supporting technology,the speedy and safe withdrawal of hydraulic supports was realized. |
