摘要：
Introduced in this paper are the test analyses of the solidification properties of the high-water-content and quick-setting materials which are used in the grouting reinforcement of broken roofs. The grouting reinforcement techniques, their parameters, and their practical applications in No.4 Mine, Pingdingshan Mining Bureau, where technological and economic benefits are remarkable for the utilisation of high-water-content and quick-setting materials as coal/rock solidifying materials to reinforce broken surrounding rock under various geological conditions.
