【摘要】：地球浅部煤炭资源逐步开采殆尽,煤炭资源开发不断走向地球深部。然而,面对深部地层环境与极限开采深度的限制,传统采矿学与力学等理论难以解决深部煤炭开采出现的技术难题,深部煤炭绿色安全高效生产面临严峻挑战。结合深地煤炭资源开发的未来趋势,提出深地煤炭资源流态化开采的颠覆性科学构想及流态化开采定义、目标与内涵,建立深地流态化开采的应力-温度-渗流-化学-微生物等多种作用机制的多场耦合模型与可视化理论,揭示煤炭流态转换的物理、化学与生物机制,建立深地煤炭资源的采、选、充、电、热、气一体化的物理流态化开采、化学转化流态化开采、生物降解流态化开采、物理破碎流态化开采等颠覆性理论和技术。在此基础上,提出"2025基础研究、2035技术攻关、2050集成示范"的战略实施路线,构建深地煤炭资源无人智能化的采选充一体化开采、热电气集成转化的流态化开采理论与技术体系,达到"地上无煤、井下无人"的绿色环保目标,实现深地煤炭资源开采的颠覆性变革。
[Abstract]:The shallow coal resources of the earth are gradually exhausted, and the development of the coal resources is moving toward the deep earth. However, in the face of the limitation of deep formation environment and limit mining depth, traditional mining and mechanics theories are difficult to solve the technical problems of deep coal mining, and the green, safe and efficient production of deep coal is facing severe challenges. Combined with the future development trend of coal resources in deep area, the subversive scientific conception, definition, goal and connotation of fluidized mining of coal resources in deep land are put forward. In order to reveal the physical, chemical and biological mechanism of coal flow transition, a multi-field coupling model and visualization theory of stress-temperature-percolation, chemical-microorganism and stress-temperature mechanism of deep fluidized mining are established, and the mining of deep coal resources is established. Subversive theories and techniques of physical fluidization mining, chemical conversion fluidization mining, biodegradable fluidization mining, physical fragmentation fluidization mining, etc. On the basis of this, this paper puts forward the strategic implementation route of "2025 basic Research Group 2035 integrated demonstration", and constructs the fluidized mining theory and technical system of unintelligent integrated mining and charging for deep coal resources and integrated thermal and electrical transformation. To achieve the green environmental protection goal of "no coal on the ground, no one in the underground", and to realize the subversive change in the exploitation of deep coal resources.
