On January 25th, the website of the Ministry of Education officially announced the winners of the 2018 Annual Scientific Research Outstanding Achievement Award (Science and Technology). Only 120 colleges and universities throughout the country won the first completed unit. Prof. Kou Ziming received the second prize of 2018 annual scientific research outstanding achievements for his outstanding work ‘The key technology and equipment project for belt conveyor belt breaking and catching’.

The received award belongs to the field of mining machinery engineering and safety engineering. In the long-distance, high-speed, heavy-duty inclined transportation process, the tape with certain tension carries all materials, and also interacts with the transmission parts to generate unreasonable periodic alternating stress and strain such as drum and idler. Under the start-stop control, sudden power failure and emergency braking conditions, it is easy to cause damage to the tape and serious accidents such as broken belts brought about by the impact load and gravity potential energy of materials. In order to solve the problems of belt wear and belt broken, Prof. Kou Ziming 's team has breakthrough in start-stop automatic control and brake reliability of belt conveyor, identification and effective capture of the broken belt during operation, and safety, efficiency, and continuous operation for broken belt replacement, by applying the theory and method of system dynamics, generalized optimization, fuzzy control, etc..

 

The achievement includes 17 independent intellectual property rights, 7 national invention patents, 10 software copyrights, 8 doctoral and master's theses and more than 10 academic papers. The main technical inventions are as follows: the fundamental vibration control scheme for limiting the elastic vibration of the belt conveyor, the key technology and equipment for the catching of the broken belt conveyor, the technology of modular stepping tape retracting, and crawler belt replacement process and technical equipment for angle, thickness adaptive control and surface backup brake. The corresponding products have achieved safe and efficient operation in more than 40 companies. The production efficiency has increased by more than 60%. Meanwhile, the significant economic and social benefits have been achieved. In the process of project research and development, the combination of actual production demand, scientific and technological innovation research and talent cultivation have been realized, which have promoted the science and technology progress of the industry, and the internationalization of scientific and technological activities.

The award is very important for the national colleges and universities, which has been rewarded individuals and organizations who have achieved outstanding results in the corresponding fields.
