摘要
通过在宁夏青铜峡地区的浅层取样钻探填图示范,介绍了浅层取样钻探设备和多种工艺方法在该地区的应用情况,总结了钻探填图遇到的问题并提出了解决方案。结合三维地质调查对钻探技术的具体要求,通过示范推广轻便浅层取样钻机具与工艺方法,使浅钻技术在浅覆盖区地质填图领域中得到应用。本文研究了适合该地区地质填图的钻探技术方法组合及钻探设备和取样器具。浅钻作为地质填图的一种技术方法可以有效地揭露覆盖层,获取基岩,提高了地质填图效率和精度,解决了制约覆盖区地质填图的技术难点,为浅覆盖区的地质填图工作提供可靠的钻探技术服务支撑。
Through the demonstration of shallow drilling in geological mapping in the Qingtongxia area,this paper introduces the application of shallow sampling drilling equipment and various process methods in the region,studies the combination of drilling techniques and drilling equipment and sampling equipment suitable for geological mapping in the region,and summarizes the problems encountered in drilling mapping and puts forward solutions. Combined with the requirements of three-dimensional geological survey to drilling technology,through demonstration and promotion of shallow sampling drill tools and process methods,it enables the shallow drilling technology to be applied in the geological mapping field of shallow overburden area. Shallow drilling as a kind of geological mapping technique can effectively reveal covering layer,obtain the bedrock,improve the efficiency and precision of geological mapping,and solve technical difficulties of geological mapping in covered area,which can provide reliable drilling technical service support.
