Researching on a New Grouting Material and its Engineering Application

Abstract

Water-irruption is the second to gas explosion of major security problems in coal mine. The grouting material is composed of fly ash and montmorillonite separately according to a certain proportion with pure cement material. On the site grouting test and compare the compressive strength of the stones of the body and the size of the diffusion radius, and compare the grouting materials with pure cement materials. Through the comparative and analysis, the reasonable grouting materials are choosen.
