摘　　要：鉴于槽探施工技术在浅覆盖区找矿应用中的局限性,开展了浅钻技术代替槽探的理论方法研究。通过在槽探拟施工区域,根据产状或覆盖层情况,布置间距小于5m的钻孔,获取基岩,来完成对矿体的评价。形成了以钻代槽勘查技术方法体系,并应用于不同的地质景观区。同时,还总结出以钻代槽勘查技术方法的操作要点,为地质调查和矿产资源勘查提供技术支撑。Due to the limitations of trenching construction technology in shallow overburden areas in explo- ration applications, research is implied on drilling technology instead of trenching theory. In a proposed trenching construction area, according to the rock occurrence, arranged hole-spacing of less than 5 meters is recommended to get rock samples to complete the evaluation of the ore body. Methodology for applying drilling applications is formed for different geological landscape areas. This paper also summarizes the technical methods of drilling instead of trenching prospecting, which provides technical support for geolog- ical survey and mineral resources exploration.
