| 近年来，浅层取样（心）钻探技术与地表基岩水平钻探技术作为新时期地质找矿工作手段，受到越来越多地勘单位的关注与试用。本文通过对浅层取样（心）钻探技术与地表基岩水平钻探技术在槽（井）探工程上的应用分析，从设备工艺、布孔要求、产状测量、样品规划及测试成效上探讨上述两种技术替代槽（井）探工程的可行性和特点。笔者认为浅层取样（心）钻探技术通过合理布孔在一定范围内可以实现部分替代槽（井）探工程的功能，从而达到减少布设槽探工作量的目的；地表基岩水平钻探技术在异常查证及厘定标志层产状、矿（化）体深部延伸情况上成效显著，可较好替代槽（井）探工程。作为技术可行、经济可控、社会效益显著的新型矿产勘查方法，合理选用上述方法势必将成为新时期地质找矿工作中行之有效的绿色山地工程手段。 |
| 英文摘要: |
| Shallow sampling (core) drilling technology and surface bedrock horizontal drilling technology, as a new era of geological prospecting methods, have received much attention and trials in many geological prospecting units in recent years. This article analyzes the application of these two technologies in trench (well) exploration engineering, and discusses the feasibility of such replacement from the aspects of construction deployment, sample specifications, and test effects. We think that shallow sampling (core) drilling technology can partially realize trench (well) exploration engineering functions within a certain range through reasonable borehole layout, so as to achieve the purpose of reducing the workload of trenching. Horizontal drilling in surface bedrock works well in verification and determination of the occurrence of the marker layers and the deep extension of the mineralization body, which can be a good substitute for trench (well) exploration engineering. As a new type of mineral exploration method, it is technically feasible, economically controllable, and has significant social benefits. So the rational selection of the above methods is bound to become an effective green mountain engineering method in geological prospecting in the new era. |
