卢安夏铜矿缓倾斜矿体开采技术研究与发展

Research and Development of Mining Method of Gentle Inclination Orebody in Luanshya Copper Mine

针对卢安夏矿带陡倾角区矿体已开采完毕,所剩缓倾角矿体产状复杂、岩石条件差,属于典型难采矿体,尝试过多种采矿方法,均未收到理想效果的难题。介绍了缓倾斜矿体开采中使用过的几种采矿方法,并分析了采矿过程中存在的主要问题及原因,结合当前国内外缓倾斜矿体开采技术的现状,提出了实现卢安夏缓倾斜矿安全高效两点建议:改进支护手段以保证工程稳定、革新采矿方法以改善经济指标。

As for the problems on mining in Luanshya Copper Mine, the steep inclination orebodies had already mined out, but the left orebodies are gentle inclination with complicated occurrence and poor rock conditions, which is a typical hard - mining orebody, and several mining methods have been tried but none is efficient. Some mining methods were introduced, and the main problems and the causes during minging process were analyzed. Based on the current mining technology situation of the gentle inclination ore- body, two safe and efficient suggestions were proposed to the gentle inclination orebodies： improving the support strength to ensure the stability and changing the mining method to improve the economy index.
