江西省于都县金塘下-窑前银多金属矿深孔钻探工程施工技术

Construction technology of deep hole drilling project in Jintangxia-Yaoqian silver polymetallic mine,Yudu County,Jiangxi Province

南岭地区是我国重要的成矿带之一,本区找矿潜力巨大,窑前区段多金属矿成矿潜力丰富。利用钻孔施工对中深部原生矿体深部及走向延伸情况和对风化壳型矿体深部隐伏原生矿体进行探索,对钻探技术及施工方案进行优化,配合完成物探测井,获取窑前区段各项地质参数,为下一步开展深部资源勘查工作,评价其工业价值提供依据。

Nanling area is one of the most important metallogenic belts in China.It has great prospecting potential and abundant ore-forming potential of polymetallic deposits in Yaoqian section.The drilling construction is used to explore the deep and strike extension of the medium-deep primary ore body and the buried primary ore body in the deep of the weathering crust type ore body,optimize the drilling technology and construction plan,complete the geophysical logging,obtain various geological parameters in the pre-kiln section,and provide a basis for the next deep resource exploration work and evaluation of its industrial value.
