破碎围岩注浆加固效果评价技术研究进展

注浆材料形成的固结体将原来松散的煤岩体固结形成一个整体,注浆效果是保证注浆工程质量最重要的一个阶段,对于注浆工程具有重要意义。详细阐述了五种注浆效果评价方法,并对其注浆效果评价方法进行了较为详细的论述与分析。指出注浆效果评价存在的问题,针对存在的问题,提出了未来需要提出注浆效果评价方法以及定量性指标;未来应研发新型物探技术,减少周围环境对于物探结果的影响;未来应该多种评价方法综合运用,边注浆边评价;未来注浆效果评价应针对不同的注浆工程提出不同的评价方法和指标。

Research and Application Summary of grouting reinforcement effect Evaluation Technology for Water-rich broken surrounding Rock

The consolidation body formed by grouting material solidifies the original loose coal and rock mass into a whole, and the grouting effect is the most important stage to ensure the quality of grouting engineering, which is of great significance to grouting engineering. Five kinds of grouting effect evaluation methods are described in detail, and their grouting effect evaluation methods are discussed and analyzed in detail. This paper points out the problems existing in the evaluation of grouting effect, points out that the evaluation method and quantitative index of grouting effect should be put forward in the future, and should develop new geophysical exploration technology in the future to reduce the influence of surrounding environment on the results of geophysical exploration. In the future, a variety of evaluation methods should be used comprehensively, while grouting should be evaluated, and the evaluation of grouting effect in the future should put forward different evaluation methods and indexes for different grouting projects.
