Agenda of the meeting on May 6th
Yang Xiaodong（杨晓东）, deputy Secretary-General of China Aggregates Association, presided over the green development Forum
Liu Bo(刘波), Chief Scientist of Hubei Chu Dao Drilling Engineering Ltd., gave a presentation entitled "Supercritical Liquefied Air Energy Storage Non-supplementary Combustion Rock Breaking Technology". He said that supercritical liquefied air energy storage non-supplementary combustion rock breaking technology is not only the original technology of Chu Dao Drilling, but also an original technology applied in large-scale mining in open-pit mines. It has several outstanding advantages. First, the technology is green, low-carbon, safe and low-cost, focusing on solving the cost problem in blasting construction in mines. Second, at the same time, it solves the tense and contradictory situation of the mine-land relationship in the blasting construction (such as safety distance control and land occupation, resettlement and relocation, etc.). Third, it alleviates the environmental problems caused by the high pulverization rate of large-scale sand and gravel aggregate mines. At the same time, it can solve the problems of blasting vibration and secondary hazards, waste of resources and noise emissions in mining, which is a good supplement to the existing blasting. The mining technology is an important supplementary technology to the traditional explosive blasting method and can be used in large-scale non-explosive rock breaking operations.
Liu Bo(刘波), Chief Scientist of Hubei Chu Dao Drilling Engineering Ltd.
Liquefied air rock breaking technology does not use any chemical materials, so it is green and low-carbon. Secondly, its use process has features of low detonation velocity, no vibration or low vibration, which effectively controls the pulverization rate of aggregate. Thirdly, it belongs to new energy technology, without explosives and dangerous chemicals, and its energy source comes from the release of air, which has no pollution to the environment. At present, it is a cutting-edge technology in the mines of the aggregates industry.
Wei Baoquan(位保全), Xuzhou Boyuan Technology Co., Ltd. Executive Vice President
Xuzhou Boyuan Technology Co., Ltd. Executive Vice President Wei Baoquan gave a presentation entitled "Dust Control Technology Equipment and Application in the Process of Ore Processing and Utilization". He pointed out that Xuzhou Boyuan Technology Co., Ltd. is a leading provider of mine dust control solutions and products in China. The company has a Jiangsu Province (Boyuan) high-pollution industrial building purification and dust removal engineering technology research center and a postdoctoral innovation practice base. It authorized more than 50 national patents and software copyrights, and its "key technology for dust partition prevention and control in the process of ore mining and utilization" was successfully selected into the "Catalogue of Advanced and Applicable Technologies for Conservation and Comprehensive Utilization of Mineral Resources" (2022 Edition) by the Ministry of Natural Resources )".
He elaborates on the relevant standards of dust control of aggregate mines; the status quo and development trend of the dust control industry; the key technologies of dust control, the design points of the dust control system; the construction of intelligent operation and maintenance platform for dust collectors and service solutions.

Symposium on stabilizing Growth
Over the past three years of Covid-19 epidemic, economic development has been greatly impacted. After the adjustment of the epidemic prevention and control policy, data show that China's economy is currently stabilizing and improving. In such a environment, how to achieve steady growth of industry enterprises is a topic that everyone must face. CAA held a symposium on stabilizing economic growth.
Song Shaomin(宋少民), vice president of the China Aggregates Association, Shao Changzheng(邵长征), consultant of the China Aggregates Association, and Yang Xiaodong(杨晓东), deputy secretary-general of the China Aggregates Association, presided over the symposium on steady growth.
The sharing and discussion covers the topic ranging from the transformation of growth and development thinking of industry enterprises, the formation of comparative advantages, the tripartite self-discipline of government, industry and enterprises, intelligent high-end equipment manufacturing, regional overcapacity, market price fluctuations, differentiated competition, green transportation, green mine construction, to high-quality, green and ecological sand and gravel aggregates, construction of various systems in the industry, innovative provision of high value-added services, resource utilization of solid waste, energy saving and consumption reduction, cost reduction and efficiency increase, and market expansion.
Everyone agrees that in the face of the opening game of industry development, it is necessary to maintain an optimistic and confident attitude, strong and active thinking, and flexible and efficient countermeasures, and to form a self-disciplined industry around the innovation of materials, equipment, processes, and models. A good industrial ecology and positive effects can safely survive the "cold winter" of aggregates industry, truly realize green, low-carbon and high-quality development, and contribute to the steady growth of our country's economy.
