Abandoned food production, as which is waste rock associated with the food, occupied large tracts of land and pollute the environment; food production would cause subsidence, thereby affecting the stability of surface buildings and destroying the groundwater systems. For this situation, the in-situ disposal innovative technique of food production was proposed, combined with industrial experimental, the general framework and principles of the technique were introduced. The gangue in-situ digestion, to achieve the gangue disposed underground and the resource recovery improved. In-situ disposal innovative technique of food production reflect the high-yield, high efficiency, safety, environmental protection, high recovery rate of scientific production system and show great theoretical and practical values to the green production technology.
