changsha evening news changsha, september 29th (correspondent mo yayu, all-media reporter chen liang) on the 28th, students from changsha changjun bilingual experimental middle school came to changsha mining and metallurgy research institute to "ride" the seabed mining vehicle "kun" dragon 500" started a "deep sea journey" 500 meters underwater.
entering the marine science and technology center of the state key laboratory of deep sea mineral resources development and utilization technology, the students of class 2301 of changjun bilingual experimental middle school seemed to be in the blue ocean. what do deep sea ores look like? how to collect and transport it? approaching the mineral resources booth, i saw various samples including manganese nodules (polymetallic nodules), cobalt-rich crusts, seafloor hydrothermal sulfides, magnesium compounds and rare earths. the students touched, smelled and had close contact with these "treasures" from the deep sea. according to laboratory staff, manganese nodules "lying" on the seabed or half-naked on the seabed are easier to collect and can be easily sucked up like a vacuum cleaner; polymetallic sulfides are formed after hundreds of millions of years of cooling after submarine volcanic eruptions. it's a bit like a coral reef; the cobalt-rich crust needs to be broken first, and then transported to the mining ship through hoses, intermediate bins, risers, and pumps, and then through a series of chemical reactions, the basic elements are extracted, and then it can be applied to our lives.
later, the students followed the scientific research ship through the video to "ride the wind and waves", feel the charm of the ocean, and explore the composition of seabed ores. at the simulated seabed experimental base of changsha institute of mining and metallurgy, dr. li xiaoyan transformed into a "captain" and the students of class 2301 became "crew members" and came to the "seabed" to have close contact with the seabed mining vehicle "kunlong 500". the yellow buoyancy belt, the "bottom of the ship" body bottom design and the special up and down lifting tracks allow the "kunlong 500" to "extricate itself" and avoid getting stuck in the soft mud on the seabed. the reliable watertight interface allows it to withstand the huge pressure on the seabed. gently stroking the tracks of the "kunlong 500" that has been launched many times, the students truly felt the power of the deep ocean.
"today's study practice has opened my eyes. the ocean knowledge and physical knowledge such as pressure and mechanical transmission that i learned in the classroom have been verified here." guo jinxin said happily. another classmate said with great expectation: "the ocean accounts for 71% of the earth's area. there are endless treasures in the ocean waiting for us to discover and mine. 'kunlong 500' can go down to 500 meters, which is very powerful. i heard that we already have the 6,000-meter-class "lushan" and we will design even better "deep-sea heavy weapons" in the future."
technological innovation and science popularization are the "two wings" to achieve innovative development. during this year's national science popularization day, changsha city actively promoted the opening of high-end scientific and technological resources such as national key laboratories to the society, including deep-sea minerals, freshwater fish development, and automobile body design and manufacturing. and other national key laboratories, combined with the high-quality science popularization resources of each venue, to carry out research practice, science popularization reports, science nights, joint check-in and other activities, building a platform for "zero-distance" contact with high technology, and inspiring the public, especially young students, to use science and technology interest, inspire awareness of scientific and technological innovation, and cultivate scientific and technological innovation capabilities.
