摘　　要：针对鄂庄井田断裂构造严重影响开采、开拓及采煤巷道布置的现状,选取7煤层底板标高为地质变量,运用趋势面分析方法,利用最小二乘法拟合,建立了4个二维多项式趋势面数学模型。通过拟合度检验、显著性检验和适度逐次检验,选取1~3次模型进行构造趋势面分析,避免盲目提高次数而使拟合方程产生不利影响。趋势分析结果与勘探成果相互验证,研究表明：鄂庄井田总体为一向斜构造,轴向NE;该向斜自井田中东部发生分叉,形成东、西两向斜,东部向斜是由2个次级向斜和1个背斜相间排列构成的复向斜构造;落差大于30m的断层在剩余图上均有较好的反映,预测了部分勘探并未查明的构造异常区域。The fracture structures of Ezhuang minefield have a strong impact on mining,exploiting and the arrangement of mining tunnel.In view of the current situation,the floor elevation of the 7 coalseam as the geological variable is selected to analyze the geological structure by means of the trend surface analysis.Four two-dimensional polynomial trend surface mathematical models are established based on the least square method.By investigating goodness-of-fit test,significance test and stepwise sequential test,1-3 trend surface models are provided to analyze the geological structure,so as to avoid increasing adverse impact on fitting equation with increasing the fitting number.The results of trend surface analysis are approximately consistent with the geological work,indicating that,Ezhuang minefield belongs to a syncline structure with the axes running NE.The syncline structure is di-vided into two parts from east-central minefield.The east syncline is a syclinoriun structure,which consists of two secondary synclines and one anticline.The fault throw greater than 30 m is well indicated in residual map,which reveals that the geological structure abnormal areas can be predicted.
