Mining conditions The Qidashan mine has nearly a century of mining history. The mining depth has reached−230 m, and its closed level is+42 m above sea level. The ore bed extends from northwest to southeast. The open-pit is about 3400 m long in the north–south direction and 800 − 1200 m along the west–east direction, as shown in Fig. 1c.
The origin of these iron deposits remains uncertain. Several workers have suggested that the Qidashan, Hujiamiaozi and Xidabei deposits are primarily of Algoma-type, and that the protoliths of the ore-bearing layers belong to volcano-sedimentary formation (Ren et al., 2007, Wang, 1986, Wang et al., 1992, Xu and Chen, 1984, Zhai et al., 1990).The major rock …
