A collaborative development framework of coal-related resources under carbon peaking and carbon neutrality goals
Combined with the characteristics of coal-related resource endowment,in this article a collaborative development and utilization concept of"safe and efficient,green and low-carbon,energy-saving and consumption reduction,exhaustion of mining,and turning waste into treasure"is proposed,the positioning of coal resources in the process of carbon neutrality is discussed,and a technical system for low-carbon and zero-carbon development of coal is constructed.It is shown that under the dual carbon goals,the coal mining industry will go through three stages:coal dominance,energy coupling,and new energy dominance.Combined with the characteristics of coal-related re-sources,and focusing on coal-heat,coal-gas,coal-water,and other associated resources in coal measures,the article reviews the development direction,status quo,and prospects of multiple CCUS(carbon capture,utilization,and storage)technologies for collaborative development of associated resources such as low carbon,zero carbon,and so on.There is an urgent need for CCUS technologies with coal mine characteristics,such as high-carbon material filling and mining in goaf areas,collaborative biomass energy development in mining areas,coalbed methane substitution mining and coal underground hydrogen production technology.Shendong mining area has realized coal water co-mining relying on underground reservoir,and the annual increase in carbon sequestration can reach 5085t.Based on the innovation of design and construction concept of underground reservoir in coal mine,a collaborative technology of CO2 storage and geothermal water extraction in deep mine goaf is also proposed.
