China R&D Instrumentation R&D On June 19, 2017, the “National R&D Center for Deep Resource Exploration Equipment†under the leadership of the Institute of Geology and Geophysics, Chinese Academy of Sciences, successfully completed the inspection and acceptance of the national key scientific research equipment development project. The results fully affirmed that the measured indicators of the systems in the project met the design requirements and agreed that the project passed the acceptance.
Mineral Resources Exploration
The eight sets of independent exploration of geophysical deep exploration equipment have not only enhanced China's deep geophysical exploration capabilities and technological level, but also provided core equipment for China to implement “deep exploration and blind exploration†and supported the national strategy of “entering deep into the Earthâ€. .
To develop space underground
With the rapid development of China’s national economy, the demand for mineral resources has increased dramatically, and reserve reserves have been seriously inadequate. China’s iron, copper, aluminum, and potassium salts have suffered from a severe shortage of major minerals and are increasingly dependent on the international market. The dependency level has reached as high as 50% to 80%, far exceeding the 40% national economic security cordon, which has become a major bottleneck restricting China's economic development.
In order to ensure the sustainable development of resources and energy, the country has clearly proposed the implementation of the resource guarantee strategy of “base on the domestic and seek for ore and increase reservesâ€. Demanding resources deep underground is one of the most important strategic choices at home and abroad.
“An important way to solve the shortage of mineral resources is to implement 'deep exploration and exploration.'†Bing Qingyun, a researcher at the Institute of Geology and Earth Sciences of the Chinese Academy of Sciences, said that the so-called “deep attack†refers to the exploration of mineral resources with a depth of 500 to 4000 meters; “exploration†is It refers to the search for underground mineral resources in covered areas such as deserts, Gobi, and vegetation.
Given the inherent penetrating ability of the geophysical field, geophysical exploration technology is the main means of "seeing and lighting" the Earth's interior, and is the key to "attacking the depth of the attack."
However, geophysics knows that it is not easy to "CT" the earth. For a long time, China’s large-scale geophysical exploration equipment and core software have all depended on imports. The research and development and production of large-scale detection equipment in the international are dominated by a few large companies, forming a monopoly on the market and being expensive, and it has begun to implement high-end products in China. Technical blockade.
“In the 1950s and 1960s, China’s geophysical equipment was actually quite strong, but it was later lagging behind by the influence of 'building a ship rather than renting a ship'.†Wu Fuyuan, academician of the Chinese Academy of Sciences and director of the Geological Earth Institute of the Chinese Academy of Sciences, frankly stated that "If we do not pay attention, our entire business will be hampered."
The backward situation of passive assault made Chinese geologists feel the urgency of the action.
"Using other people's equipment to explore China, we cannot tolerate it."
“The number of papers in China has been among the top in the world, but why are the original major innovations still lacking? I think this is largely because we haven’t really unified science and technology. The backward concept must be changed."
This feeling of Zhu Rixiang, an academician of the Chinese Academy of Sciences, originated from his own personal experience. Although he is engaged in basic research work, using foreign equipment to look at the underground of his country makes him feel "intolerable". "China cannot always be controlled by people and must make its own equipment."
In 2013, under the planning and coordination of the Chinese Academy of Sciences and the Ministry of Finance, the Institute of Geology and Geophysics of the Chinese Academy of Sciences received support from the “National Research and Development Center for Deep Resource Exploration Core Equipment†for the development of a major scientific research and development equipment of the Chinese Academy of Sciences, organized strengths, and began research and development of autonomous equipment for up to four years.
The project selected the satellite magnetic measurement load, aerospace superconductivity full tensor magnetic gradient measurement device, aviation transient electromagnetic surveyor, prospecting gravimeter, and multi-channel high power according to the technology urgently needed for the mineral resources exploration and exploration process. Electrical exploration equipment, metal mine seismic detection system, deep deposit logging system, combined deep sea exploration equipment, 8 sets of deep resources exploration equipment development mission, the goal is to independently research and development of deep resources exploration core equipment technology, for our country "underground 4000 meters The Earth Transparency Plan lays the technical foundation.
After four years of hard work, the development of eight sets of equipment has been completed. Some of the equipment and technical indicators have reached the international advanced level, breaking the monopoly of foreign countries, and a number of key technologies have filled the technical gaps in domestic related fields.
The sweetness of independent innovation
What makes Zhu Rixiang unpredictable is that the technological level achieved by some equipment development has far exceeded the goal set four years ago. The speed of application and promotion of some core components and equipment also exceeded expectations.
For example, the satellite magnetic load system has independently developed fluxgate magnetometer engineering prototypes, proton precession magnetometer engineering prototypes, magnetic detection calibration systems and data calculation software. Third-party testing shows that some of the technical indicators are better than the design indicators and reach the international advanced level. The entire technology supported the establishment of the Mars magnetic field exploration mission, and won the first-stage project development and optimization of the China Mars Exploration Project payload.
In addition, the prototype of the airborne superconducting full-tensile magnetic gradient measurement device has participated in resource exploration, engineering archaeology, and defense application; the aviation transient electromagnetic surveyor has carried out metal ore exploration work for the Armed Forces Gold Force in Shandong and Inner Mongolia; Seabed seismic exploration equipment has been applied by CNOOC and Fujian Seismological Bureau.
For Wu Fuyuan, in addition to upgrading the level of China's geophysical equipment, the project also cultivated a technical team to allow Geological Earth to grow into a full-chain research institute covering theoretical research, technological R&D, and industrialization. In order to protect this technical team as much as possible, the Institute basically abolishes the original assessment system and advocates that all scientific researchers conduct work around the world's technological frontiers and major national needs. “We have no articles here and we can be research fellows. Allow failure, but must do something."
The implementation of the four-year project broke through core technologies such as sensors for deep exploration equipment, which laid an important foundation for realizing high-resolution exploration of 4,000 meters of deep mineral resources in China, and provided strong technical support for the national resource and energy security system.
Today, Zhu Rixiang’s “Long March for Equipment Development†has already taken the first step, but the team has not stopped. At present, the team has actively participated in the project-related work of the national special deep-earth exploration equipment task on the basis of the project as a technology basis. It will continue to tackle key problems in 10 to 15 years to promote the practical application of deep exploration equipment. Industrialization, breaking foreign monopoly.
"The Japanese cameras are easy to use because they have been constantly innovating for many years." Wu Fuyuan said, "The project passed the acceptance test today, but it is not an end. We hope that it can become a start."
