摘　　要：为确定大尹格庄2号矿体-616 m水平85～88线采场稳定性,对85～88线节理裂隙进行实测,节理产状通过DIPS软件分析,得到优势节理有2组,结构面为北东一南西走向,2组优势节理组的倾向和倾角分别是倾角41°,倾向316°和倾角58°,倾向146°;根据调查结果利用Q值对岩体进行分类,可以得到85～86.5线的7个采场矿岩稳定性较好,86.5 ～ 87.5线的4个采场矿岩稳定性一般,88线上部7106采场矿岩条件较差.研究结论可靠,为下一步参数优化的分区应用提供了参考和依据.In order to determine the stope stability of line 85 to line 88 at -616 mlevel of No. 2 ore body of Day- ingezhuang,its joint fissures are measured. According to the joint occurrence, and through the DIPS software, it is obtained that there are two dominant sets of joint with the structural plane of NE-SW in strike. The inclination and orientation of the two dom- inant joints are 41° and 316° ,58° and 146° respectively. Based on site investigation ,the rock mass are classified according to the value of Q. It is concluded that 7 stopes from line 85 to line 86.5 has a better stability,4 stopes from line 86.5 to line 87.5 is in general and No. 7106 stope at line 88 is worse. With a reliable conclusion,the study provides the reference and the basis for the zoning of parameters optimization.
