一汉中天台山磷矿，位于南秦岭东西构造带地槽区内，构造复杂。该矿床处于一背斜构造之中，地层陡峻，倾角在80°—90°之间。地层总的走向北东60°，整个岩矿层受构造之影响，折曲、褶皱纵横交错。在岩性上，主要是沉积变质的石英片岩、炭质千枚岩、磷矿层、含锰白云岩及其石英岩等。其主要物理机械特性是软硬极不均匀，一般在5—9级之间频繁变化，片理、节理发育，部分地段硬、脆、碎，部分地段软、松、散，易坍塌，取芯均很困难。
A Hanzhong Tiantaishan phosphate rock, located in the South Qinling East-West tectonic zone of the trough area, complex structure. The deposit is in an anticlinal structure with steep strata with dip angles between 80 ° and 90 °. The strata generally go to north east 60 °. The whole rock and ore layer is affected by the structure and is folded and folded in a crisscross pattern. In lithology, it is mainly metamorphic quartz schist, carbonaceous phyllite, phosphate rock, manganese-bearing dolomite and quartzite. The main physical and mechanical properties of the hard and soft are very uneven, usually in the 5-9 level between the frequent changes, film management, joint development, some sections of hard, brittle, broken, some sections of soft, loose, loose, easy collapse, coring Are very difficult.
