蒋家河煤矿综放工作面巷道变形机理分析

Fully Mechanized Working Face Roadway Deformation Mechanism and Influence Factors Analysis of Jiangjiahe Coal Mine

通过对彬长矿区蒋家河煤矿综放工作面掘进和回采期间巷道变形特征分析,总结了巷道变形机理,认为主要诱导因素为底板淋水软化后的塑性变形应力重新分布,造成巷帮和顶底板的变形加剧。蒋家河矿采取的联合补强支护和起底、扩帮、挑顶等一系列综合治理措施有效治理了软底巷道变形,具有一定的借鉴意义。

By analysis of Binehang mining area jiangjiahe coal mine working face roadway detormation characteristics during excavation and mining, summed Up the roadway deformation mechanism, think the main indueing factors are the bottom pouring water softening plastic deformation leading to stress re-distribution, resulting in roadway sides and roof and floor deformation seriously. Jiangjiahe coal mine take joint reinforce branch support and repair, expansion wall, the top pick etc. which are a series of comprehensive management measures effective governance of the soft bouom roadway deformation, have certain reference significance.
