条带开采是国内外应用最广泛的控制地表沉陷、保护地面建筑物和生态环境的技术,同时也是绿色开采技术体系的主要技术措施之一。条带开采地表移动变形预测是进行建筑物下条带开采设计的关键,文章通过分析多煤层条带开采地表移动实测数据,建立了多煤层条带开采地表移动预测参数与条带开采宽度、层间距、上下煤柱空间位置关系等的关系,为多煤层条带开采地表移动预测参数选取提供了可行的方法。
The strip mining is a most widely applied technology at home and abroad to control the surface ground subsidence and to protect the surface buildings and the ecological environment and is one of the main technical measures to the green mining technical system.The prediction on the surface ground movement deformation caused by the strip mining in underground would be the key to the design of the strip mining under the surface buildings.With the analysis on the site measured data of the surface ground movement caused by the strip mining in multi seams,the predicted parameters of the surface ground movement caused by the strip mining in the multi seams,the strip mining width,the distance between the seams,space location relationship between the coal pillars in the up seam and low seam and other relationship were established in order to provide the feasible method to the collection of predicted parameters of the surface ground movement caused by the strip mining in multi seams.
