基于钻孔岩心观测的煤田构造研究

Coalfield Structural Study Based on Drilling Core Observation

含煤岩系钻孔岩心上常见的变形构造现象有褶皱、节理、断层等,它们对分析研究区煤田构造有着重要的意义。含煤岩系钻孔岩心中变形构造的描述,包括岩层产状、岩石变形结构、变形构造(连续变形和非连续变形)等内容。通过对构造现象的观测,获得定量数据,并对比不同钻孔的特征,为分析煤田构造特征提供依据。

Familiar deformed structures have fold, joint and fault etc. on coal-bearing rock drilling cores, they are important in the study area coalfield structural analysis. The description of deformed structures in coal-bearing rock series drilling cores include strata occurrence, rock deformation texture, deformed structures （continuous and discontinuous deformations） etc. Through the structural observations, have acquired quantitative data, compared characteristics of different boreholes, and thus provided the basis to analyze coalfield structural features.
