深部接续开采高边坡治理研究与实践——以晋宁磷矿东采区为例

Research and practice of management of high slope in deep mining with East Mining Area in Jinning Phosphate Mine as example

通过对最近10年晋宁磷矿东采区高边坡治理工作的梳理,针对边坡固有特点,对边坡多方法治理进行研究。考虑矿体的埋藏条件、矿山开采工艺、技术条件和设备,采用顺层清方处理矿山临时边坡与强采和分段实施内排相结合,内排压帮开采效果明显,取得了良好的资源效益、经济效益和社会效益。

Research was conducted on the treatment of slope with multiple methods by review of the recent 10 years of treat- ment of high side in light of the inherent characteristics of slope. The temporary slope in mines was treated by removing earthwork in bedding combined with reinforced mining and inward dumping in levels taking into account the buried conditions for orebody and the mining technology and technical conditions and equipment in the mine. The effect of mining on slope with inward dumping was significant with good resource, economic and social benefits obtained.
