Shandong Energy Group Co,. Ltd. is a large state-owned energy enterprise group in Shandong Province, upon an agreed merger between the former Yankuang Group and the former Shandong Energy Group. It has made remarkable achievements in safe and efficient coal mining, high-end equipment manufacturing, coal gasification, coal liquefaction, coal clean utilization, and overseas development, and has played a leading and exemplary role in the development of the national coal industry. This paper systematically summarized the development layout and innovation system construction achievements of Shandong Energy Group, progressed in 15 key areas including the top coal caving in thick coal seams, fully-mechanized mining with super large mining height, intelligent mining in medium-thickness coal seams, rock burst control, roadway support technology, mine heat hazard and coal spontaneous combustion prevention, mining "under the buildings, the railway and the water and above confined water", deep well construction, Australian coal development practice, high-end equipment manufacturing and coal clean utilization are sorted out, and some typical successful cases. This paper systematically expounded the development layout of Shandong Energy Group in the aspects of investment in science and technology, platform construction, industrial transformation, new industry, digitalization and intelligence, and introduced the experience and achievements of innovation system construction of Yancoal Group and the policies and guidelines of technological innovation system construction of new Shandong Energy Group. The great contribution made by the group in the popularization and application of top-coal caving mining technology in thick coal seam was reviewed, and the technological innovation in fully-mechanized top-coal caving mining technology and supporting equipment was introduced. For safe and efficient mining of coal under different geological and production conditions, the fully-mechanized mining technology and complete equipment with high and super-high mining height of 3-4,

5.5, 6.0, 6.8, 8.2 m with different burial depths and different coal types have been studied and developed. The development and application of technology and equipment for 5.5 m and 7.7 m large and super-large mining height fully-mechanized top-coal caving mining have been completed, and the mining height of fully-mechanized top-coal caving in China has been updated. The current situation of rock burst mines in Shandong Energy Group were illustrated, the group's ideas and technologies in rock burst control were analyzed, the engineering practice of rock burst control under three typical strata conditions of Ordos, Heze and Xinjiang were mainly discussed. The development and reform process of anchor-net support in the group were reviewed, and the research results of large-section gob-side entry, small coal pillar gob-side roadway, deep complex roadway layout principle and support technology were summarized. Aiming at the management of mine heat hazard and coal spontaneous combustion prevention, the principle and application of the centralized cold water cooling system and the total air volume cooling system in Zhaolou Coal Mine were introduced, and the research and application of early identification technology of coal spontaneous combustion, closed control technology of gob and emergency control technology of spontaneous combustion fire were summarized. The research results of overburden failure characteristics, mining subsidence law and reasonable retention of water proof coal pillars were introduced, and the practical experience of coal mining under rivers, village buildings, railways, high-voltage transmission lines, and oil pipelines were summarized. The mature experience in the process of deep shaft construction was introduced, such as surface pre-grouting, deep shaft freezing construction, shaft wall masonry, shaft support, shaft wall rupture prevention etc. The development experience and achievements of Yankuang Australia's development, acquisition process, mine construction, and intelligent working face were sorted out. The multi-nozzle coal-water slurry gasification technology with its own intellectual property rights was developed, and a series of furnace models with different pressure grades of 4.0 MPa and 6.5 MPa for daily coal treatment of
