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。
Based on the analysis of a large number of measured data and the current research results, the influence of geological mining factors on the offset distance is studied. The influence mechanism of geological mining factors on the offset distance is discussed in detail in combination with the masonry beam structure hypothesis. The study suggests that the size of the inflection point depends mainly on the formation of hard rock layer of the masonry beam structure, and other factors are related to it.
