摘要
8102工作面于回采过程中揭露了一处陷落柱,该陷落柱靠近8102工作面回风顺槽。通过对8102工作面陷落柱进行探查和治理,防止碾焉煤矿8102综采工作面在过陷落柱回采过程中发生奥灰突水事故;运用三维并行电法、无线电波透视2种探测技术结合钻探情况对注浆效果进行验证,并对注浆治理效果进行评价。
A collapsed column,close to the return air gateway of 8102 working face,was exposed in the mining process.The exploration and treatment for the collapse column were implemented to prevent the Ordovician water inrush accident when the 8102 fully mechanized working face passing the collapse column in Nianyan Coal Mine.In addition,three-dimensional parallel electrical method and radio wave perspective method were combined with drilling conditions to verify the grouting effect and evaluate the grouting treatment effect.
