on June 26, the national "12th Five Year Plan" intelligent manufacturing equipment development special project "development and demonstration application of intelligent system for complete sets of coal mining equipment" passed the appraisal of scientific and technological achievements organized by Shanxi Provincial Department of science and technology in Taiyuan, reaching the international leading level. It marks that China's coal machinery industry has taken the lead in achieving phased results in the process of moving towards "made in China 2025", and China has taken an important step towards the realization of "unmanned coal mining face"

this phased achievement is the result of joint efforts and collaborative research by many parties. It is a model of independent innovation, integrated innovation, collaborative innovation and the deep integration of "two modernizations" between coal machinery enterprises and coal enterprises

there are many innovative highlights and broad market prospects

after identification, all mechanical performance indicators and intelligent functions of the project have met the design requirements, completed the automatic control of the coal production process of the ten million ton fully mechanized mining face, met the use requirements of the coal mining face with large mining height and thick coal seams, and has a broad application prospect. The overall technical performance index of this achievement has reached the international advanced level

the appraisal committee spoke highly of the project and believed that its most significant innovative highlights were: first, it developed a distributed airborne monitoring and control system, which realized the rapid data processing, reliable information transmission and improved the intellectualization of the shearer. Secondly, the height adjustment control model based on profiling cutting is established, and the height adjustment device of Shearer Based on electro-hydraulic proportional control technology is developed to realize the adaptive adjustment of shearer drum height. Thirdly, a fault diagnosis model of the shearer rocker transmission system based on the envelope technology of a holding listed company with diversified vibration acceleration and professional development of each plate is established, and an intelligent fault diagnosis system of the shearer transmission system is developed to realize the condition monitoring and fault identification of the rocker transmission system under underground mining conditions

in order to complete the 15 key core intelligent devices of the scientific research project, Taiyuan Heavy Machinery Group Coal Machinery Co., Ltd. and Xishan coal power (Group) Co., Ltd. have actively organized Pingyang heavy industry, Shanxi coal machinery, Shanxi Keda, Luoke Jiahua, Xiangming machinery, Fenxi heavy industry and other units to participate in the scientific research project, and have cooperated with China University of mines, Taiyuan University of technology, Taiyuan University of science and technology and well-known enterprises at home and abroad to tackle key problems, It took three years to complete the equipment design, key technology research, manufacturing and demonstration application. The equipment investment is 379 million yuan. Among them, the national subsidy of 100million yuan is the largest project in the national intelligent equipment development special program of the 12th Five Year Plan. For example, Yamaguchi University in Japan and Tongji University in Shanghai have established corresponding links with covestro

the industrial test for more than a year shows that this set of intelligent fully mechanized mining equipment has achieved independent innovation in the "design, manufacture and application of fifteen key core intelligent devices", reaching the international advanced level. Under complex geological conditions, this set of intelligent fully mechanized mining equipment operates normally, stably and reliably, and all the equipment can automatically coordinate the operation, realizing the automatic control of the shearer, hydraulic support and transportation system, and has the ability of monitoring, automatic diagnosis and fault early warning, reaching the intelligent control requirements of the coal production process of the ten million ton fully mechanized mining face. Its intelligent transmission network speed reaches 100Mbps, the network self-healing time is less than 20ms in case of single point of failure, the network transmission delay is less than 1ms, and the wireless network transmission rate reaches 54Mbps; The maximum daily output of raw coal is 32000 tons, and the maximum monthly output is 850000 tons. Through collaborative research and integrated innovation, at present, it has 52 patents with independent intellectual property rights (including 23 invention patents and 29 utility model patents), and a number of technologies fill the international gap, and the price is more than 30% lower than that of similar imported products

according to experts, this set of equipment integrates the most advanced technology at home and abroad, forming an advanced new process of high-yield, efficient and intelligent mining. The number of operators in the working face is reduced from 12 to 16. Generally, the speed range is narrow. If there is high speed, there will be no low speed or if there is low speed, there will be no high speed to 4 to 6 people. The per capita efficiency is increased by 50%. The safety production efficiency and social benefits have reached the international leading level, and have a broad market prospect. More importantly, its popularization and application can change the traditional production mode of mechanical coal mining, complete the leap from underground machine following operation to remote control coal mining operation, and greatly improve the production safety and intensive mining level

combination of independent innovation and integrated innovation

at present, a new round of industrial revolution is emerging in the world: in terms of production mode, manufacturing presents the characteristics of digitalization, networking, intelligence, personalization, localization, greening and so on; In terms of division of labor, it shows the characteristics of manufacturing service, specialization, product chain integration, and division of labor in the industrial chain. "In the new round of scientific and technological revolution and industrial reform, all countries are studying how to seize the commanding height of the new round of development." Miao Wei, Minister of the Ministry of industry and information technology, said, "the integration of informatization and industrialization is the commanding height we should seize, and the main direction is intelligent manufacturing. Promoting intelligent manufacturing is the fundamental path to solve the problem of China's manufacturing industry from big to strong."

as we all know, there is still a certain gap between China's coal machinery manufacturing industry and the world's advanced level. Especially in the development of complete sets of intelligent fully mechanized coal mining in underground coal mines, due to late start, large investment, little experience and other reasons, both research and development and practical application are at the initial stage

as a major coal producer in the world, China's overall technical level and innovation ability of coal machinery lag behind the advanced level of world powers. Therefore, the national development and Reform Commission, the Ministry of Finance and the Ministry of industry and information technology, in accordance with the spirit of the 12th Five Year Plan for national economic and social development and the decision of the State Council on accelerating the cultivation and development of strategic emerging industries, decided to jointly organize and implement the "special project for the development of intelligent manufacturing equipment", Accelerate the innovative development and industrialization of intelligent manufacturing equipment in China

the national intelligent manufacturing equipment development special project "intelligent system development and demonstration application of complete sets of coal mining equipment" led by Taizhong coal machinery company and Xishan coal power company is of great significance to the development of intelligent manufacturing equipment in China

the author believes that for the research and development of a number of key areas and key core technologies, the state should give full play to the role of policy guidance and financial support to encourage advantageous enterprises to actively innovate independently and integrate. "Graphene should be used as a new star in the material industry for the development and demonstration of intelligent system of complete sets of coal mining equipment" project, the total weight of the equipment is more than 10000 tons, and the equipment cost is 379 million yuan, of which the State supports 100million yuan. Without national policy guidance and financial support, it is difficult to imagine that such a huge underground intelligent complete set of equipment can be successfully developed in a short time and rank among the world's advanced levels. China's manufacturing industry has changed from big to strong, which is inseparable from the national policy guidance and financial support

in the process of moving towards "made in China 2025", advantageous enterprises should be proactive, dare to take responsibility, and play a leading and exemplary role. In this regard, Taizhong Coal Machinery Co., Ltd. and Xishan coal power company can be regarded as a model of cooperation between the coal machinery industry and the coal industry. During the "Eleventh Five Year Plan" period, the two enterprises cooperated to complete the national science and technology support project "complete sets of equipment and key technologies for large mining height fully mechanized mining with an annual output of ten million tons of coal mines"; This second cooperation, from scheme discussion, to R & D and manufacturing, from ground linkage commissioning to industrial tests, is commendable. It not only sets a new benchmark for the cooperation of coal machinery enterprises, but also plays a positive role in promoting the innovation and development of coal machinery industry in Shanxi and even the whole country. In addition, we should also have cross-border thinking, be good at learning from each other, work together to tackle key problems, and actively take the road of combining independent innovation and integrated innovation

China is the largest manufacturing country in the world, but it is not yet a manufacturing power. There are still a number of major technologies and equipment to be broken through, and there is still a lack of a large number of internationally competitive backbone enterprises. Therefore, this time, China's first intelligent complete set of fully mechanized mining project successfully passed the appraisal of scientific and technological achievements, which is an important milestone for China's manufacturing industry to change from big to strong
