超大采场充填体性能模拟分析研究

The numerical simulation to the stability and mechanical properties of filled body in super large stope

矿山采用充填法开采,能够有效防止地表出现沉降和塌陷,环境意义重大。当矿岩条件允许时,大参数的采场还能够大幅提升矿山的生产效率和降低生产成本。但是在生产中,充填体的性能要求对于矿山的安全、生产成本具有很大的影响。为有效降低生产成本和保证矿山生产安全,本文主要对超大采场中充填体的稳定性和受力性能进行了分析,初步探讨了充填体在采场中发挥的作用。

Filling mining methods can effectively prevent the deformation and subsidence of the surface, and protect the environment better than other mining methods. If the ore conditions permit, the large-scale stope can greatly improve the mine production efficiency and reduce the production cost. But during production, the performance of the filling body have a great impact on the safety, production cost of the mine. In order to reduce production costs and ensure safety, in this paper, the stability and mechanical properties of the filled body in the super large stope are analyzed, and the role of the filled body in the stope is preliminarily discussed.
