针对深孔复杂夹层（断层）和溶洞地层钻进的护壁困难，常规护壁方法无法解决的问题，提出并研究试验成功了高压旋喷水泥浆护壁技术，经多个矿区、钻孔的实践证明，高压旋喷水泥浆护壁法可以在任意孔深的坍塌超径孔段、软弱松散地层等形成可靠、有效的“水泥套管”护壁。系统介绍了该项技术的工艺原理、技术要点及其推广应用情况。

Aimed at the wall protection difficulties in multiple interlayer and karst stratum, which can not be solved by tra-ditional wall protection means, high pressure jet grouting cement slurry technology was put forward and successfully devel-oped.By the practice experiences in several mining areas and boreholes, the reliable and effective “cement casing” has formed by wall protection technology with high pressure jet grouting cement slurry in collapse and oversized hole sections in any depth and loose strata.The paper systematically introduces this technology about its process principle, the technical points, the application and popularization.
