采用国际岩石力学学会推荐的详细线观测法对自走铁矿的节理裂隙进行了调查。用频率分布直方图统计了结构面间距和倾角。认为巷道为节理密集、发育的碎裂岩体。借助理正软件对调查数据进行分析,绘制出节理裂隙赤平极射投影极点等密度图和优势产状的分组表。将用于隧道稳定性判断的方法引入到巷道中,对自走铁矿的岩体稳定性进行了分析,认为节理对巷道的稳定性不利,建议巷道进行锚杆加固或喷砼等措施。

Detailed observation line method has been used to investigate the joints of Zizou iron mine which was recommended by International Society for Rock Mechanics.Discontinuities spacing and dip angle have been counted with column diagrams.There are joint fissures and disintegrate structure rock mass in the roadways.Contour plot and major planes table have been drawed to analyze the joints survey data of Zizou iron mine by geological software Li zheng.At the same time the method of mathematical statistics has been used to analyze the geometric characteristics of each set of joints.The criterion of tunnel stability has been introduced into the roadways.Jonints are harmful for stability of rock mass of Zizou .We suggested that the anchor reinforcement or concrete spraying should be used.
