采动岩体破裂规律的试验研究

Study on Laws of Rockmass Breaking Induced by Mining

在相似材料模型试验基础上，获得了岩体破裂、离层裂缝发育及采动岩体碎胀规律，给出了离层裂缝高度和长度计算及注浆孔位置确定的表达式。

Based on the simulation test, the laws of rockmass breaking, bed separation development and broken rock bulking are gained, and the calculation of the height and length of bed separation and the determination of plane and bed locations of grouting drillholes are discussed. The research provides a theoretic basis for the choosing of the locations.
