Studies Of Coal Resource Flowing Rule And Its Substitution Mechanism

Instructed by circular economy and sustainable development theory, and based on the induction of resources flowing research and resources substitution research, this paper primarily analyzed resources flowing rule, coal resources flowing rule, the basic principles of resources substitution and coal resource substitution mechanism. The paper mainly includes:(1) Resources flowing rule analysis. This part analyzed resources fluidity at first, afterwards, it analyzed resources flowing usage, which can de divided into three mobile ways, that is, resourcesâ†'…â†'resources, resourcesâ†'processingâ†'resources, resourcesâ†'abandonâ†'renewable resources. Finally, it analyzed resources flowing routes, which include linear mobile way, tree mobile way, ring-like mobile way and net mobile way.(2) Coal resources flowing rule analysis. This part analyzed coal resources' spatial flowing rule at first, and 30 coal resource flowing province (city, area) can be divided into three large-scale systems, which is output system, input system and reserve system. And then, it analyzed coal resource flowing rule between exploitation, washing, deep processing and using, including material transformation and energy transformation.(3) Basic principles of resources substitution analysis. This part emphasized the basic principles of resource substitution, proposed that homogeneous resource has multiple functions, one demand can be satisfied by different resources, based on the characteristic of resources' multipurpose and diversification of satisfying one use, it causes the existence of common application domain, independent application domain between related resources. Based on that, it continues on the resource output analysis: unitary throw into unitary output analysis, unitary throw into various output analysis, various throw into various output analysis and various throw into unitary output analysis. Following that, it established resources substitution standard, which include quantity standard and value standard. Take unitary throw into unitary output analysis as an example, it computed resources substitution coefficient, and then established resources substitution scheduling table, in order to analyze the relations and order of resources that can be substituted mutually. Based on that, it conducted one resource multi-purposes analysis and one field different resources analysis, and analyzed the function of resources substitution.(4) Research on coal resource substitution mechanism. Take Xinwen mining group as an example, it analyzed resources substitution between coal exploitation, washing, deep processing and using, including gangue, water-coal-slurry, home scrap etc. that can substitute coal resource. Following that, it analyzed the usage of coal, petroleum, the solar energy, the nuclear energy and hydro-energy, based on that, it established substitution analysis table between coal and these resources. At the end, it analyzed the substitution of coal to petroleum from its necessity, significance, technology and resources' reserve and market feasibility.
