摘要:

为了确保东露天安全高效开采,需要对其采空区上覆顶板岩层安全厚度做出详尽、合理的计算。首先整理得到计算所需的多种参数,在此基础上,通过利用工程经验类比法和数值模拟方法,综合分析得出采空区上覆岩层安全厚度的合理数值,并拟合得到了采空区安全厚度计算公式,分析结果对同类露天矿山具有借鉴和指导作用。

Abstract:

In order to ensure safe and efficient mining in East Open-pit Mine, the author needs to make the detailed and reasonable calculation on the safety thickness of goaf roof rock. Based on the parameters for calculation, through utilizing engineering experience method and numerical simulation method, the article comprehensively analyzes the reasonable value of goaf roof rock safety thickness and obtains the calculation formula of goaf roof rock safety thickness, whose results have the reference and guidance value for the similar open-pit mine.
