赵家寨煤矿绞车房加固技术研究

Research on Zhaojiazhai Coal Mine Hoist Room Reinforcement Technology

针对赵家寨煤矿-140 m31采区主绞车房硐室破坏情况,分析了破坏原因,采取锚网锚注联合加固技术,前期对主体硐室顶部补打锚网、局部巷帮浇灌,后期以整体混凝土浇灌为主,待凝固后,对绞车房帮顶进行浅孔围幕注浆加固。施工速度快,费用省,成功地修复加固了受到破坏的硐室和基础。

In view of the Zhaojiazhai mine -140 meters 31 mining damage to the main winch room cavern,analyzes the damage reason,take the anchor net anchor note joint reinforcement technology,prior to the subject heading at the top of the fill,local anchor net on the lane to help watering,concrete casting as a whole is given priority to,late after being frozen,shallow hole was carried out on the winch room help top side curtain grouting reinforcement.It raised construction speed,cost down and succeeded in repairing the damage of the cavern and the foundation.
