Abstract: In order to reduce the dangers of safety production in coal mine from water flowing subsided column, the collapse column grouting reinforcemet is a very effective means. Based on the governance engineering of NO.2 collapse column in the 19108 working face Pingshuo Underground mine One, discussing the collapse column grouting reinforcement techniques, using the governance principles of “While construction, while analysis, while optimizing design”, puts forward the end of the grouting engineering standard and the governance effect testing method. The results show that:collapse column development characteristics is the premise of grouting reinforcement governance. Reasonable drilling layout and grouting parameter selection is the key technology of grouting reinforcement governance. Grouting to dilute before they are thick and grouting pressure increased gradually from 2 to 6 MPa. Inspection hole engineering quality inspection, the original exploration hole water yield and water quality analysis is the effect of effective testing method. Finally, 19108 working face safe passing 2 # collapse column after the governance.
