【摘要】：在大型煤电基地建设中,优化煤炭的供应渠道和供应量、提高电厂燃煤废弃物的有效利用是目前急需解决的问题。本文在运输成本最低的前提下,对煤和粉煤灰在各矿井及各电厂间的供应关系及供应量进行了研究。根据矿井和燃煤电厂之间的地理位置分布、煤炭供求关系、矿井开采能力,采用最优化理论和方法,建立"煤一粉煤灰"双向物流模型,满足运输成本最优的目的。根据建立的模型,求得矿井与燃煤电厂之间煤炭供应量和煤矿井下粉煤灰回填量分配最优解以及双向物流分配方案,并确定了需建设的皮带运输路线的总长度。为煤炭开采、煤电就地转化和粉煤灰井下回填,提出一种新的循环经济产业模式。
[Abstract]:In the construction of large coal-power base, it is urgent to solve the problem of optimizing the coal supply channel and supply and improving the effective utilization of coal-fired waste in power plant. The supply relationship and supply of coal and fly ash in coal mines and power plants are studied. According to the geographical distribution of coal and coal-fired power plants, the relationship between supply and demand of coal, and the mining capacity of mines are studied. By using the optimization theory and method, the bi-directional logistics model of "coal-fly ash" is established to meet the purpose of optimal transportation cost. The optimal solution of coal supply between coal mine and coal-fired power plant and the optimal distribution of coal ash backfill and two-way logistics distribution are obtained, and the total length of belt transportation route to be constructed is determined, which is coal mining. A new industrial model of circular economy is put forward by converting coal and electricity in situ and backfilling coal fly ash underground.
