砂金是勘探投资小、见效快、经济效益高的国家急需矿产。我队在内陆江河砂金矿中钻探已有十六年的历史。随着勘探工作的开展,部分矿体埋藏在水面以下需要进行水上钻探,而内陆江、河水上钻探刚刚兴起,缺乏定型设备。为此,我们针对矿区没有疏通航道、水深多变、河流弯曲复杂等特点,自行设计了一种螺旋升降式活动平台——嘉陵号。这种活动平台是钻探船和钻探平台的组合体,具有钻探船台和钻探平台两种钻探设施的优点。它既是承载
Gold is an exploration investment in small, quick, high economic efficiency of countries in urgent need of minerals. Our team has been drilling in the inland river sand and gold mine for about 16 years. With the exploration work carried out, some of the ore body buried beneath the water surface needs to be drilled in water, while inland rivers and river water drilling have just started to rise, lacking stereotyped equipment. To this end, we do not dredge the fairway for the mining area, changing water depth, river bending and other characteristics of complex, designed a spiral-type activities platform - Jialing number. This activity platform is a combination of a drilling vessel and a drilling platform, with the advantages of both drilling platforms and drilling platforms. It is both bearing
