The Application of Grouting Technology for Governance of Mined-Out Area under Large Channel


Article Preview

The research on key technology of mined-out grouting filling management in large channels is carried out based on the geology and distribution characteristic, according to YUZHOU coal mining area on the main channel of the middle rout in the South-to-North water transfer project. This article describes the formula of the goaf governance width, material liquid ratio of filling and sealing grouting, and studies the drilling and grouting technology and then proposes the methods and standards of grouting quality inspection which combines the comprehensive analysis of geological CT scanning, grouting texting and grouting result of data.
