摘要
针对现有地表下沉预计精度偏低的问题,文章基于矿区的煤柱压缩量这一因素,利用FLAC进行了建模分析,提出煤柱压缩量与煤柱尺寸的关系式,并给出两种形式的基于煤柱压缩量的地表下沉预计公式。研究表明,考虑这一因素为精确预计地表下沉提供了可行性。
According to the fact that there is no enough prediction accuracy of the existing surface subsidence,this paper modelled and analysed the factor that based on the coal pillar’s compression amount using the FLAC,raised the relation formula about the size of the coal pillar and the pillar’s compression amount,and put forward two forms of predict formulas induced by the pillar’s compression. The Study showed that,considering this factor can provide precise prediction’s feasibility for the surface subsidence.
