济宁煤田岱庄井田断层构造特征及其对生产的影响

济宁煤田为鲁西地区的主要煤田之一,岱庄井田位于济宁煤田的中北部,总体呈向SE倾斜的单斜断块构造。岱庄井田内构造以断裂为主,NE向、近SN向和NW向3组断层互相交叉、切割,致使煤层错动,影响工作面和巷道的布置,造成煤炭资源的损失。该文通过对已有地质资料的分析研究,提出在今后生产过程中应采取探、采结合的方式查明断层的构造特征,以达到充分合理开发煤炭资源的目的。

Characteristics of Faults and Its Influences on the Production of Daizhuang Well in Jining Coalfield in Shandong Province

Jining coalfield is the main coalfield in the southwest region of Shandong province. Daizhuang coal mine locates in the middle and north part of Jining coalfield. It is a monoclinic structure with the trend of SE. The structures of Daizhuang coal mine are faults and folds with the trend of NE, nearly SN and NW. Three groups of faults cross and cut each other. It has caused dislocation of coal strata and influenced the layout of working face and roadway. Through study on the former geological information, it is regarded that exploring and mining should be combined in production process in the future to identify the distribution of faults. Thus, adequate and reasonable exploration of coal resources can be gained.
