Abstract: The article has achieved the goals that all industrial wastewater was recycled，and all industrial waste residue was effectively utilized，and all the lime kiln gas was processed in low cost and low carbon way，through adopting core technology （including ‘pyramid’ plan for calcium chemical products，core processing technology of coal，and core technology of water cycle cascade utilization） of resources comprehensive utilization of large-scale calcium carbonate mine.The core technology had provided some reference for future large-scale calcium carbonate mine resource utilization，recycling economy and low-carbon economy.

Key words: large calcium carbonate mine, calcium chemical products, comprehensive utilization, water cycle cascade utilization
