Performance results of the 313 Geological Team of Anhui Provincial Bureau of Geology and Mineral Exploration

The 313 team has discovered and verified 56 types of minerals, more than 300 various types of mineral deposits and mineral producing areas in the western Anhui region, and more than 70 small-scale or above-sized mineral deposits. Among them, there is the Huoqiu Iron Mine, which ranks first in East China, with proven resources of 1.65 billion tons; there are more than 10 production areas of gold and silver and other precious metals, lead and zinc and other polymetallic minerals, Huoshan Gold Mine, Jinzhai County Mercury Cave Chongqing Lead and zinc mines have been mined by the local government and have achieved good social and economic benefits; there are dozens of metallurgical auxiliary raw materials, building materials and other non-metallic minerals. Won 4 scientific and technological progress awards at or above the ministerial level, and more than 30 awards of various types at or above the provincial or ministerial level.

Team 313 has achieved remarkable results in special drilling, tunnel (hole) construction, pile foundation construction, and engineering survey. In terms of special drilling, the team has used the patented directional drilling technology to complete the directional docking construction of salt mine drilling in Guangzhou, the construction of ground settlement observation holes in Shanghai, the construction of vertical holes for reservoir dam displacement observation, and the undisturbed soil core drilling in northern Jiangsu. Construction and other projects; in terms of tunnel (cave) construction, we have completed the construction of water diversion tunnels such as Qianshan Leigongjing Hydropower Station, Chuzhou Langyashan Hydropower Station, Jinzhai Liubo Hydropower Station, etc. In terms of pile foundation construction: it has completed the pile foundation construction of Shanghai Kaikai Commercial Building Project, Yingchangqi Weiqi School Project, Nanjing Shimao Binjiang New City Project and other projects. It fully demonstrates the comprehensive strength of Team 3 in geological exploration and market revenue generation, and enjoys a certain reputation both inside and outside the province.

In 2011, Team 313 completed the drilling of a 2,706.68-meter-deep small-diameter rope coring drill using domestic machinery, setting a new benchmark for drilling in the country.

In 2014, Team 313 completed the "Development of Split Tower Fully Hydraulic Power Head Drilling Rig and High-Strength Rope Coring Drill Rod" project. This project is the first in China to comprehensively summarize a complete and highly adaptable small-diameter deep core drilling technology system. The research results have been widely used in Anhui Huoqiu deep ore prospecting, Shouxian Iron Mine, and Jinzhai Shapinggou Molybdenum Mine. , Chuzhou Mingguang Salt Mine and other mining areas and the Wenchuan earthquake fault zone scientific drilling WFSD-3 hole, Jiangxi Ganzhou 3000-meter scientific drilling NLSD-1 hole, Anhui Lucong 3000-meter scientific drilling LZSD-1 hole and other different formation drilling holes have obtained good results. Among them, the hole depth reached 2706.68 meters in the deep prospecting in Huoqiu, Anhui in 2010, setting the deepest record for small-diameter geological core drilling in my country that year, and producing significant social and economic benefits. The research results of the project also provide a research basis for the next step of my country's deep exploration technology strategy of 10,000 meters into the ground, as well as drilling projects in shallow oil, water resources, geothermal, seismic, scientific drilling and other fields.
