[Explanation] In Shenfu New District, Liaoning Province, a technology company developed a robot system 100 days after resuming work to fill the gap of China's large-section rectangular coal tunnel shield tunneling robot.
[Commentary] At the beginning of 2020, the eight national ministries and commissions jointly issued the "Guiding Opinions on Accelerating the Intelligent Development of Coal Mines", which clearly took 10 to 15 years to complete all coal mine automation and intelligent upgrades. The Shenfu New District, a technology company, is responsible for the core sub-project of a key project in this field and the "large-section rectangular coal tunnel shield-type rapid tunneling robot system", but a sudden new pneumonia outbreak But it disrupted the original plan. Therefore, when the resumption of production and production started, this project became the top priority of the technology company.
[Same period] Qiu Yang, deputy dean of a research institute of a science and technology company: Honestly, when we first started this project, I personally felt that it was impossible to complete the construction period. Just uphold this belief. Anyway, this task must be completed and must be won. So all of us, not only we engage in technology, including production is that all people work overtime to do this thing. I did not expect that it would really succeed.
It is reported that the "large-section rectangular coal tunnel shield-type rapid tunneling robot system" developed in this study can effectively improve the current coal tunnel mining efficiency. Under its reasonable application scenario, it can reduce the current mining speed of large coal tunnels in China. Increase nearly 5 times.
[Same period] Qiu Yang, deputy director of a research institute of a science and technology company: the current cutting method is used. If the conditions are slightly better, such as a month, it can reach 300 to 400 meters of cutting. Speed, four hundred meters. If we use our equipment, our goal now should be at least two kilometers.
It is reported that the breakthrough of this technology company in Shenfu New District, in addition to its own strong R & D capabilities, is closely related to the local policy of resuming production and resuming production. And the double help of funds can actually solve the difficulties of enterprises. At present, Shenfu New District has a total of nearly 500 reinstatement enterprises and nearly 20,000 reinstatement workers. More than 85% of the enterprises have achieved the expected production capacity, and have gradually embarked on a healthy development track.
