新集一矿地质构造特征研究

Study on Geological Structure Characteristics of Xinji No.1 Mine

矿井地质构造是影响煤矿生产建设最重要的地质条件之一。本区地质构造条件中等,小断层较发育,严重制约了矿井采掘工作的进行。运用地质统计方法等手段对新集一矿地质资料进行分析和研究,认为本区断层走向以北东向为主,北西向为辅,正断层和逆断层均有发育,褶皱较为宽缓。已发现的断层有182条,断层将井田切割成近东西向的多个条块,在剖面上呈现为阶梯状、地堑、地垒组合特征。根据矿区地质构造特征,对其可能引发的地质灾害进行了研究分析,并提出了工作建议。

Mine geological structure is one of the most important geological conditions affecting the production and construction of coal mines.The geological structure conditions in this area are medium,and small faults are relatively developed,which seriously restricts the mining work of the mine.This paper analyzes and studies the geological data of Xinji No.1 mine by means of geostatistical methods.It is believed that the strike of the fault in this area is mainly NE,supplemented by NW.Both normal and reverse faults are developed,and the folds are relatively wide and gentle.There are 182 faults that have been discovered.The faults cut the mine field into several blocks in the near east-west direction,showing the characteristics of ladder,graben and horst combination on the profile.According to the characteristics of the geological structure of the mine,the possible geological disasters are studied and analyzed,and the work suggestions are put forward.
