At present, the construction of Shaanxi's modern industrial system is being accelerated. "There is a sea of coal in northern Shaanxi, which is of high quality and easy to exploit," read an article published in a major Chinese newspaper on October 18, 1984. As the basic plate of Shaanxi industry, the transformation and development of energy is under way. In 2023, Shaanxi's coal and oil production will rank third, fourth and third in China respectively. In accordance with the direction of green and low-carbon development, Shaanxi is promoting high-end, diversified and low-carbon development of coal chemical industry, and building a national clean energy base.

Sitting behind the office coal mining is the epitome of intelligent mine construction. In the mine, tens of thousands of sensors, like antennae, perceive the production situation in real time, and the underground information highway built by 5G+ industrial Internet technology can upload information at a millisecond speed, so as to realize the accurate control of the ground personnel in the mine.

What can a lump of coal become? It could be clothes, it could be a plastic bottle, it could be this superabsorbent particle used to make diapers, all thanks to the magic of modern coal chemistry. To make the most of this magic, the catalyst is the most important element.

The high-throughput catalytic reaction research platform built by artificial intelligence is the "magic room" to find the catalyst formula. The robot arm will put the catalyst into the reactor and automatically carry out the catalytic reaction experiment. The computer automatically captures all the experimental data and analyzes it to find the best reaction conditions.

With the blessing of science and technology, coal is realizing the conversion from black to white. In Yulin, coal-to-ethanol and coal-tar hydrogenation already account for 50% and 40% of China's total capacity, respectively. And in Binzhou, Shaanxi Province, more than 500 kilometers away, the original coal mining solid waste coal gangue, etc., has also "turned waste into treasure", becoming wallpaper, cement, mortar and other building materials.

The construction of underground reservoirs in coal mines is a major initiative in the field of green coal mining. Different from the general artificial reservoir, using the physical space of the mined-out area of the coal mine, through the artificial dam body, the mine water produced by mining is stored, through the natural filtration and purification of the mined-out area and the treatment of surface waste water, the mine water can realize the classification and utilization.
