摘要
安徽省两淮地区属全掩盖式煤田,在煤田的发现及开发阶段物探资料(重、磁、电、地震)具有不可替代的作用。两淮地区地层存在着明显的密度界面、磁性界面、电性层界面及波阻抗界面,与其相对应的重力场、磁场、电场、地震等地球物理特征反映了不同时期的沉积环境及区域构造特点。根据煤系地层与其它岩层的物性差异,提出了应用物探资料分析煤系赋存规律的方法及控煤构造综合解释方法。
The Huainan and Huaibei coalfields in the Anhui Province are all totally Cenozoic covered coalfields.The geophysical prospecting information（gravitational,magnetic,electric and seismic） acquired during the coalfield discovery and development stages will play an irreplaceable role.Density,magnetic,electric and wave impedance interfaces can obviously reflect strata in both coalfields.Geophysical characteristics of corresponding gravitational,magnetic and electric fields and seismic information have reflected depositional environments and tectonic features during different periods.According to physical property differences between coal measures and other strata,an integrated interpretation method to analyze coal measures hosting pattern and coal controlling structures put forward.
