分析了饱水粉细砂层顶板的地质环境及其工程地质特性，开发了适应其特殊性及现有施工条件的一种新式超细水泥注浆加固工艺。工程的完工和地面监测资料说明，这种新方法对顶板流砂层可进行有效的控制
The geological environment and engineering geological characteristics of the top of saturated fine sand layer were analyzed. A new type of superfine cement grouting reinforcement technology was developed to adapt to its particularity and existing construction conditions. The completion of the project and ground monitoring data show that this new method can effectively control the roof runoff
