【摘要】 为研究蔚县煤田逆掩断层发育特点及构造应力场,在二、三维地震资料解释的基础上,通过对地震解释成果的分析并结合了钻孔和巷道揭露资料,对比研究了构造域中逆断层叠覆宽度大、延展距离长且多顺层推覆的特点和发育规律,认为该区域逆断层发育的应力场构成应该以垂直挤压重力应力场为主。分析成果很好地解释了蔚县区域内各种资料所揭示的煤系地层中逆断层发育情况。更多还原

【Abstract】 In order to study Yu County coal reverse fault development characteristics and tectonic stress field,based on 2d and 3d seismic data interpretation, through the analysis of the results of seismic interpretation, combined with drilling and roadway expose data, the reverse tectonic domain cascade with large width, long extension distance and the characteristics and development regularities of bedding nappe were studied, it was considered that the regional stress field of reverse fault development should give priority to field with vertical extrusion gravity stress. The analysis result explained the Yu County area revealing various data of strata reverse fault development well in coal series strata.更多还原
