摘要
针对某矿厚冲积层大采深条件下的地表和岩层移动规律展开研究,通过建立地表移动变形观测站,获取了现场实测数据,采用理论分析和数值模拟等相结合的方式,求取了该矿厚冲积层大采深条件下的地表和岩层移动变形规律。利用1st Opt数据处理软件分析了地表移动变形特征,得到了实测岩移角量参数,采用1st Opt软件回归分析得到了地质采矿要素与岩移参数间的关系式;并通过数值模拟,分析了厚冲积层大采深条件下采动岩体的应变特征和地表移动变形分布特征。
Research on movement law of surface and rock strata for a mine with great mining depth and thick alluvium is carried out. Through the establishment of surface movement and deformation observation station,the field data are obtained. With use of theoretical analysis and numerical simulation method,the deformation laws of surface and rock strata for a mine with great mining depth and thick alluvium is gained. Surface deformation characteristics are analyzed by using 1st Opt data processing software,and the field rock shift angle parameters are measured. The regression analysis by 1st Opt software can gain the relationship of geological and mining factors and rock movement parameters. Through the numerical simulation,the strain characteristics of mining rock and the distribution characteristics of surface movement and deformation under conditions of great mining depth and thick alluvium are analyzed.
