中文摘要	在新疆东天山玉海戈壁荒漠浅覆盖区,开展1∶5万机动浅钻化探方法技术试验研究,在玉海矿区开展采样层位识别与采样、采样粒级选择等方法技术试验。结果表明,采样层位识别可依据物质组分、样品颜色、颗粒磨圆度、泥质含量、硬度差异、钻机信息等判断;初步认为采样层位应是穿过第四系、新近系及强风化黏土层后,依据各取样孔实际层位情况,依次选择风化岩层-半风化基岩层-基岩层采集机动浅钻1m进尺内的样品;采样粒级建议选择-4~+80目。以此为依据,在玉海矿区及外围56km~2的范围内,开展1∶5万机动浅钻化探应用示范。结果表明,在已知矿区获取清晰的成矿元素地球化学异常,且在矿区外围发现新的矿致异常。因此,试验提出的机动浅钻化探方法技术可用于类似东天山浅覆盖区1∶5万化探调查。
英文摘要	The motorized shallow drilling technology for 1∶50000geochemical exploration sampling has been carried out in Yuhai shallow overburden area area,where is the the Gobi desert in East Tianshan,Xinjiang.This paper introduces how to recognize the sampling layer and to select the sampling grain level and other method and technology tests in the Yuhai mining area.The results indicate that the sampling layer can be recognized by its mineral constituent,sample color, hardness difference,clay quantity,drilling information,and particles content with a homologous psephicity.It is preliminarily thought that the sampling layer is under the Quaternary,Neogene and strong weathered clay layer.In terms of the real layer in drill hole,the samples have been successively collected from the completely weathering layer,partly weathering layer and bedrock layer with a grade of-4~+80mesh in one meter in shallow drilling.According to the results of this experiment,the explicit abnormal of ore-forming elements in the mining area and its surroundings have been obtained through the shallow drilling technology for 1:50000geochemical survey in Yuhai region,with an covering area of 56km~2.In consequence,the motorized shallow drilling technology can be used for the geochemical survey in the kind of geomorphic environment, such as,the shallow overburden areas in the Gobi desert of East Tianshan.
