安庆铜矿2#矿体开采稳定性研究

矿山岩体稳定是保证矿山安全生产的前提条件,因工程地质条件方面的差异和地质工程结构的复杂性,决定了矿山需要解决的工程岩体稳定问题。针对安庆铜矿2#矿体赋存条件的特征,为确保矿体安全、顺利回采,开展了现场岩体工程地质调查,进行了岩石力学参数测试,在收集和整理原有资料的基础上,对其进行了岩体质量评价,运用Mathews方法进一步评价了岩体稳定性。为矿山安全开采提供了重要的基础资料和依据。

Study on Stability of Caving 2# Orebody at Anqing Copper Mine

The rock mass stability is a prerequisite condition of ensuring safety in production.It is different engineering geology factor and complexity engineering geology structure,which decide the mine to need brain storming.In light of the characteristic of store condition at Anqing Copper Mine,the rock mass engineering geology is surveyed on the site for the safe and successful recovery the orebody.The rock mass mechanical parameter was measured.On the base of collection and collating data,The rock mass quality was evaluated.Mathews method was used to evauate the rock mass stability.The important material and foundation were provided for safety exploitation in the mine.
