宁阳煤田为鲁西地区主要煤田之一,石桥井田位于宁阳煤田西区的南部,井田内广泛发育以石炭~二叠系和中奥陶统假整合面为主滑面的多级重力层滑构造,本文在分析其成因基础上,结合实际揭露情况对井田内层滑构造发育特征进行总结,并对层滑构造对生产的影响进行分析,对指导矿井生产有重要的实际意义。
Ningyang coalfield is one of the major coalfields in Luxi area. Shiqiao Minefield is located in the south of the western part of Ningyang coalfield. In the well field, a multi-level gravitational layer mainly composed of Carboniferous-Permian and Middle Ordovician pseudo- Based on the analysis of its causes, this article summarizes the developmental characteristics of the inner layer slippery tectonics in the minefield and analyzes the influence of the layering structure on the production, which has important practical significance for guiding the mine production.
