中文摘要：
针对司家营铁矿南区的阶段嗣后充填法采矿设计要求,开展了矿床工程地质和采矿技术条件研究。首先在矿床地质构造和围岩特性分析基础上,进行矿体与围岩分类,由此对矿岩体进行稳定性评价,并确定了矿岩体力学参数;然后,利用矿区的探矿钻孔,建立了三维矿床地质模型,展示了矿体空间形态以及品位分布规律;最后,借助于工程经验和前人的研究成果,初步探讨了矿区的地应力参数。研究成果为矿床的充填法采矿设计和优化决策奠定了基础。
英文摘要：
According to the stoping design requirements of the deposit with sublevel backfilling in South Area of Sijiaying Iron Mine,the research is carried out about engineering geological condition and exploitation technical condition of the mineral deposit.On the basis of ore-body＇s geologic structure and the characteristic analysis of the surrounding rock,the ore-body and surrounding rocks are classified,and the rock stability evaluation is made so as to determine the mechanical parameters of rock mass.Then,the spatial form and the grade distribution of deposit are shown by using the 3D geologic model of deposit which is built with use of the exploration and drilling data.Thus,By means of engineering experience and previous research results,the ground stress parameters of the ore district are preliminarily discussed.The research results lay a foundation for mining design with back-fill method and decisions optimization.
