为了对金川Ⅲ矿区进行采矿技术条件评价及采矿方法分析,开展了矿区的工程地质调查与研究。根据工程地质调查和节理裂隙分析,得出矿区节理条件以及矿岩体稳定性影响。通过对矿岩物理力学特性的分析,揭示了在整个矿区中,矿石稳定性最好,下盘次之,上盘最差,且由于断层的存在,矿床岩体存在软弱破碎带。同时,对多种不同的勘探资料进一步进行分析,得出了该矿区的节理间距、节理产状从北东向北西偏转以及岩石破碎程度等特征。这些调查和研究,为金川Ⅲ矿区进行采矿方法及关键技术研究提供了基础数据,并为下一步的研究奠定了理论基础。

The research on engineering geology of deposit is an important basis for selection of mining technical condition evaluation and mining method. This paper launch the engineering geological investigation and study,for the study of mining method in the 3rd mining area of Jinchuan.The results of geological analysis are as follows:this mining area is an independent mining area which formed due to faulting, the joint development, its surface smooth and rise steeply, between them exists so many secondary compounds,so the rock is not stable.Research on the rock physical and mechanical properties of mine showed that in the whole ore rock,the ore is the most stable rock,and the second is the footwall, and the worst is the hanging wall.Due to faults,ore rock exists soft fractured zone.Finally,this paper fully uses a variety of exploration data,reveals the mine joint spacing,the rock is crushed and the strike of joint occurrence is North East to North West.Those studies provides basic data for the research on the key technology of mining method,and laid the foundation for the next research.
