摘要
针对近水平露天矿山尽早实现内排,缩短运距,而且内排土量越大经济效益越显著,那么内排土场帮坡角和内排土场稳定性就成为问题的关键。本文结合宝日希勒露天矿工程背景,运用FLAC^(3D)、Ansys数值模拟方法对内排土场基底、地下水等主要影响因素进行研究,揭示了软岩基底内排土场岩体变形、移动规律、滑坡机理并提出防治措施,保证露天矿安全生产并获得最大经济效益。
To carry out the inpit dump as soon as possible in flat dipping surface mine can shorten the haul length effectively.Moreover,the more the inpit discharging volume is,the more prominent the economic benefit is.Then angle of the slope and the stability of the inpit dump are the most critical problems.In this paper,according to the engineering background,the author studies such key affecting factors as the basement of the inpit dump,the groundwater and so on with the methods of numerical simulation(FLAC^(3D) and Ansys),discovers the deforming and moving law of the rock mass and the mechanism of the landslide,then puts forward the preventive measures, which can make the surface mine product safely and obtain the maximal economic efficiency.
