The soft rock stratum, possessing the characteristics of poor anchorage and large deformation, is frequently encountered in underground coal excavation where stability of the whole mining structure is always affected by the soft rock. Therefore, the bolt-grouting support technology in pursuit of an effective way for stability control of soft rock chamber of coal mine in china is conducted. Meanwhile, strata behaviors monitoring is carried out in the chamber to verify effect of bolt-grouting support. The results demonstrate that bolt-grouting goes well in soft rock chamber support.
