In the 70 years since the founding of new China, China's coal output has increased by 114 times. Huangyuzhi, director of Sinochem news National Coal Mine Safety Supervision Bureau, said on the 21st that in the 70 years since the founding of new China, China's coal output has increased from 32 million tons at the beginning of the founding of new China to 3.68 billion tons in 2018, a net increase of 114 times. The coal and carbon supply has changed from a serious shortage to an overall surplus of capacity, and the supply and demand are basically balanced

huangyuzhi said at the 2019 world robot Conference Coal Mine robot forum held in Beijing on the same day that since the founding of new China 70 years ago, China's coal industry has undergone earth shaking changes. While coal production capacity has increased significantly, coal 3 The exposed sliding parts, gears, pulleys, etc. of the testing machine shall be protected; The industrial structure has been continuously optimized. The number of coal mines has been reduced from about 82000 in 1997 to less than 5700 at present by rectifying the order, shutting down wells and reducing production, closing down and bankruptcy, resource integration, merger and reorganization, and elimination and exit of backward production capacity. The number of coal mines has been reduced from 19, including the closed-loop control system composed of Jinan assaying loading servo Electromechanical, high-precision displacement measuring mechanism control, and high-precision load sensors. The concentration of the coal industry has been greatly improved, and the number of coal mines has been reduced from more, smaller, scattered A historic leap to large bases, groups and coal mines

at the same time, the level of coal mine technology and equipment in China has also been significantly improved. According to huangyuzhi, at present, China's complete sets of equipment with an annual output of 10million tons of fully mechanized mining equipment, shearers, hydraulic supports and transporters have reached the world advanced level. The 8.8m super high intelligent fully mechanized mining face has been successfully applied. The mechanization of coal mining and tunneling has reached 78.5% and 60.4% respectively. 183 intelligent mining faces have been built. Coal production has changed from manual operation to mechanization, automation, informatization A historic leap in intelligence. China's coal mines have achieved "three significant reductions" in the total number of accidents, major and extraordinarily serious accidents and the death rate of one million tons

coal is the main energy and important industrial raw material in China. "In the 70 years since the founding of new China, the coal industry, as an important basic industry, has strongly supported the steady and rapid development of China's national economy and society." Huangyuzhi said
