On October 26, the Shaanxi Institute of Engineering, Energy, Chemical, and Circular Economy was held in Xi'an. Thirty academicians provided advice and suggestions on how to develop a recycling economy and achieve sustainable development of low-carbon and green energy in the Shaanxi energy and chemical industry. Experts said that while dedicating themselves to the development of coal chemical industry, they must look for realistic and reliable new technologies and focus on industrial layout to promote CO2 emission reduction. Xie Heping, academician of the Chinese Academy of Engineering and president of Sichuan University, said that while CCS is internationally recognized as the main way to reduce CO2 emissions, CCS’s security is worrying and more recognized from the current situation. In fact, carbon capture and utilization technology. Currently, carbon dioxide is hydrogenated to produce methanol and carbon dioxide-based biodegradable plastics. Because of its high cost, high energy consumption, short carbon cycle, and small industrial scale, the role of carbon emission reduction is also not significant. He believes that, relatively speaking, a carbon capture and utilization technology (CCU) that utilizes the abundant calcium and magnesium ions in the earth's crust for carbon dioxide is more realistic and reliable. Research shows that as long as the use of 1% of calcium and magnesium ions in the earth's crust to mineralize carbon dioxide can meet the human carbon emissions reduction needs of 85,000 years. Because CCU technology can produce chemical products or building materials while mineralizing carbon dioxide, it can produce economic benefits, thus making CCU more competitive. Academician Xie Kechang, vice president of the Chinese Academy of Engineering, suggested that Shaanxi should attach great importance to the optimization of the industrial chain of coal mining, upgrading, transformation and utilization. Taking Shaanxi National Coal Chemical Industry Group's State Key Laboratory as a research and development platform, we will jointly develop more research institutions and jointly develop key technologies such as coal pyrolysis and gasification. Jin Yong, an academician of the Chinese Academy of Engineering, pointed out in his report that as the severity of crude oil increases and the degree of inferiority increases, as well as the increase in the production of natural gas and unconventional natural gas, and the scale of methanol to olefins, the disadvantages of naphtha to ethylene have become increasingly apparent. The economics of the integration model will be tested. He suggested that Shaanxi Province prudently deploy an integrated ethylene refinery project, focusing on the development of coal-medium temperature retorting - tar hydrogenation for the production of clean liquid fuels and MTO, MTP, MTA (coal-based aromatics) projects, and the use of coal for "three "Alkene" and "trihydrocarbons" then produce high value-added products such as plastics, rubber, coatings, polyesters, nylon 66, and so on, reducing carbon dioxide emissions per unit of production value. In addition, academicians of the Chinese Academy of Engineering Cao Xianghong, Liu Tianjun, He Jipeng shared their research results with the industry on how to promote the energy saving and emission reduction of the oil refining industry, the efficient green mining of coal, and the efficient recycling of magnesium resources. The anchor drilling rig is mainly used in hydro power stations, railways and highways, in order to prevent and control various geological disasters, anchoring operations are carried out on landslides and dangerous rock masses.It is mainly used in landslide and dangerous rock anchoring projects in tunnels, railways, highway slopes and other kinds of geology, especially for high slope rock anchoring projects. Drilling operations consume less manpower and material resources, have high construction efficiency and high safety factor. It is also suitable for the construction of deep foundation pit support, reinforcement hole for anti-float anchor and foundation grouting, blast-hole in blasting project, high pressure sprinkling stake and tunnel pipe support hole, etc..

The drilling technology with casing of anchor drilling rig is designed to solve the problem that complex rock layers cannot be holed. The drill bit impacts rock continuously, and the broken rock is blown to the ground by the air pressure discharged from the gap between the casing and the drill pipe. The drill pipe and bit can be lifted after punching the hole, and the casing is placed in the middle of the rock layer, so that the rock layer doesn't collapse.
