全区已发现矿产9大类31种，约占全省已发现矿产的23%，发现各类矿产点160余处，探明储量的矿种15种，其中：钛铁矿、石墨矿属国内特大型矿产，储量分别为600万吨和400万吨以上；石灰石、石膏、芒硝、花岗岩和煤炭等非金属和能源燃料类资源在西北占居优势，其中煤炭探明储量10.68亿吨、油页岩2.48亿吨、芒硝773万吨、石灰岩11.7亿吨、石膏1.4亿吨，由于地质勘探程度低，综合开发利用率低，目前开发利用的矿种仅占全区矿种的30%，对外合作开发潜力巨大。

METHODS: The 15 hybrid dogs were randomly divided into 2 groups. In the experimental group (n=9), a hole was drilled at the slope beneath the tibial plateau to reach the medullary cavity. The cavity was enlarged by an appropriate drill to confirm the size of the cavity. The absorbable polyamide intramedullary rods were inserted from the hole in tibial superior extremity, and the fracture was anatomically reduced with the rod passing through the fracture. Two locking nails, which were cylinder polyamide rods, were respectively located 2 cm from the cutting site, in the distal and proximal ends. Auxiliary plaster external fixation was performed for 4 weeks. In the control group (n=6), quincunx intramedullary nails of the same diameter with 4 pre-drilled holes were accordingly inserted into the cutting segment, and 2 screws were locked in the distal and proximal ends, respectively.
