摘    要:根据淮南矿业集团潘一矿2171(1)工作面开采实践,采用相似材料模拟实验。利用电子经纬仪与数字散斑相关方法相结合监测位移,分析研究了采场上覆岩层的“三带”特征及分布规律,上覆岩层移动发展趋势、演化规律、存在范围及形态,以及与开采宽度的关系。结果表明:一定采宽后顶板垮落规律显著,断层下顶板周期断裂步距减小;岩层下沉系数与岩层高度和采厚比成线性关系,上覆岩层沉降具有非对称性;离层裂隙的发生、扩展、闭合受关键岩层的影响和控制。数据分析还表明,数字散斑相关方法具有较高的精度,这一新的研究方法引入,丰富了上覆岩层活动规律的研究手段。本文结果可为指导工程实践提供重要理论依据。

关 键 词:深部开采  上覆岩层移动  相似模拟实验  数字散斑相关方法

Abstract:Accordding to the working face 2171(1) mining practice in Panyi Mine of Huainan Mining Industry Group Limited,the characteristics and the distribution rules of the "three zone" of overlying strata in the working face were studied based on similarity simulation experiment with electronic altometer and digital speckle correlation method to survey displacement.The development tendency,propagation rule,existence scope and shape of overlying strata movement and its relation with the mining width were analyzed.Re...
Keywords:deep mining  overlying strata movement  similarity simulation experiment  digital speckle correlation method
