| Abstract: | Based on coal goaf governance engineering,this paper introduced the selecting principle of parameters for advanced periphery grouting and analyzed the advantages,disadvantages and range of whole or half section grouting method.Besides,the construction materials and equipment as well as the construction technology about advanced periphery grouting are introduced.Finally, the grouting effects were analyzed by the method of analysis and inspection hole respectively.Re-sults indicate that the water inflow was controlled,the loose rock mass was reinforced after ad-vanced periphery grouting. |
