河北某磷矿是该省正在设计基建的大型采选联合企业。矿床自上而下有Ⅰ、Ⅱ、Ⅲ号等三个矿层,如图一所示,均赋存于杂岩矿内的层状辉面石岩带中上部;矿层分布东西长1718米、南北宽1480米、标高598～32米之间,矿层埋深达200左右。矿层总体走向北50°～60°东,两端分别向北及北西弯曲,形成各矿层有规律的弧形弯曲,矿层同向中心倾斜,倾角25°～40°,顶部和转弯处倾角较大,矿层产状稳定,形态简单,呈向南
A phosphorite mine in Hebei is a large mining and dressing complex under construction in the province. There are three ore layers Ⅰ, Ⅱ and Ⅲ in the ore deposit from top to bottom. As shown in Fig.1, the ore deposits are all located in the upper part of the strata - Width of 1480 meters, elevation 598 ~ 32 meters, the depth of about 200 ore. The ore body is generally 50 ° to 60 ° northward to the east and both ends bend to the north and northwest respectively, forming regular arcuate bending of each ore layer. The ore layer is inclined to the same center with an inclination of 25 ° -40 ° and a large inclination at the top and corner , Stable and stable shape, shape is simple, was south
