摘要
利用钻探可连续取心的技术特点,可查明第四系地层序列,控制基岩顶面埋深与起伏、验证推测模型、研究地质构造、圈定地质体间的重要接触关系,服务于填图。通过浅钻技术在敖汉旗四图幅覆盖区填图中的应用,总结出一套适用于荒漠草原浅覆盖区填图的钻探技术方法组合,并归纳出利用浅层钻探技术开展覆盖区填图的技术操作要点,为相似景观区区域基础地质调查和矿产调查提供技术支撑。
By using the drilling characteristics of continuous coring, the Quaternary stratigraphic sequence can be found out, and then top surface depth and fluctuation of bedrock determination, estimation models verification, geological struc- tures research, delineating important contact relation between geological bodies can be realized and can be used for geolog- ical mapping. Based on the application of shallow drilling technology for geological mapping in Aohan County, a set of drill- ing technical methods combination is summed up, which is suitable to the geological mapping in shallow overburden area of desert steppe, the key points of technical operation for overburden area mapping by shallow drilling are presented, which provides technical support for geological survey and mineral resources exploration in similar landscape area.
