摘　　要：本文在分析大量实测资料的基础上，结合目前的研究成果，研究了地质采矿因素对拐点偏距的影响规律，结合砌体梁结构假说详细讨论了地质采矿因素对拐点偏距的影响机理。研究认为拐点偏距的大小主要取决于形成砌体梁结构的硬岩层，其它因素的影响都与它有关。Abstract Based on a lot of in — situ data and current research achievments, the influence of geological and mining factors on displacement distance of inflection point has been studied. After analysis using articulated beam hypothesis, it is recognized that the magnitude of displacement distance is mainly dependent on the feature of hard rock seam formed articulated beam. All the influences due to other factors are related it.
