Preventing and Minimizing Mining Disasters through Grouting

Abstract
The generation of rock bursts is closely related to overburden movement. Particularly in the condition of a hard and thick overlying strata in deep mining, the impact of a rock burst is even more prominent. A special geological mining condition of the giant thick overlying conglomerate of Huafeng mine was used as the background for this study, and the influence of overburden characteristics on rock bursts was discussed. Due to the development of large-scale bed separation in the lower part of the conglomerate, the conglomerate layer was in both relatively stable and unstable states, and the mechanism of a rock burst under these two conditions was studied. According to surface observations and downhole microseismic monitoring, the conglomeration movement was divided into five stages. The law of rock burst occurrences in each stage was analyzed, which showed that the occurrence of rock bursts periodically changes with variations of the conglomerate movement stage. Combined with the application of bed separation grouting, it has been shown that the risk of downhole rock bursts can be reduced by suppressing the movement of conglomerates through grouting technology.
