摘要
针对豫北隐伏隆起区边缘形成的宽裂限盆地开展研究,分析研究目的区构造特征及地质条件及控煤因素,在实际应用中进行隐伏煤田勘探。首先,在豫北隆起区寻找凹陷并预测煤田赋存条件,再通过高分辨率反射波地震等物探方法及钻探验证,分析"隆中凹"煤田地质构造特征及其控煤因素,形成河南省内甚至国内开展相关的技术方法和找矿模型研究,进而成为寻找新的煤炭资源潜力接替开发地的重要方向。运用该研究方法对整个华北地台隐伏隆起区内部找煤具有重大的意义,并结合某煤普查项目综合研究,取得良好的找矿效果。
Through the research on wide rift basin at the edge of concealed uplift region in the north of Henan province,tectonic feature, geological conditions and coal controlling factor were analysed and studied, and concealed coalfield exploration was carried out in the practice. Firstly,searching for depression in the north of Henan province,and forecasting the occurrence condition of coal,through high resolution reflection wave seismic exploration method and drilling verification, tectonic feature of ＂ depression in uplift＂ and its coal con- trolling factor were analysed in the paper,and formed related technical methods and the focus of exploration model of Henan province, even the whole country, secondly, the new trend has been formed for the search of the new coal resource potential, and it is to look for to replace an important direction of development. Using the research method has great and direct significance of the North China platform concealed uplift interior for coal,combined with a coal census project used to obtain good results.
