摘要
以煤层采空区治理工程为依托,详细介绍了超前周边注浆参数的选取原则,讨论了全断面注浆和半断面注浆作业的优缺点和适用范围.介绍了周边注浆施工材料、设备及施工工艺,采用分析法和检查孔法对注浆效果进行了对比分析.结果表明,采用超前周边注浆加固,能有效控制涌水量,加固松散岩体.
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.
