彬长矿区软底巷道底臌影响因素及防治技术

Effect factors and control technology of floor heave of soft floor roadway in Binchang mining area

巷道底臌是彬长矿区软低巷道底板变形和破坏的一种主要方式,通过分析彬长矿区蒋家河煤矿二采区三条大巷底臌的综合影响因素,提出通过巷道起底、锚注和控制水治理技术,使巷道底臌得到了很好控制,效果良好。

The floor heave is a major way of roadway deformation and failure in Binchang mining area. By analyzing the floor heave causes of main roadways in second mining district of Jiangjiahe coal mine,the comprehensive treatment technology of roadway maintenance,bolt- grouting reinforcement and water control was proposed. The application shows that the technology can control the roadway floor and the effect is very good.
