A Scheduling Model of Coal Supply Chain Based on Supply
A coal supply chain can be represented as a flow map in fig.1 where the departments of coal washery act as nodes and links related with coal logistics and sub-process among the facilities. There are several external nodes involved the set of customers, e.g. the third party logistics for coal transport, the coal companies those Barring a few instances, a coal washery does not form part of a coal mine in India. Total installed capacity of washeries in India is around 131.24 million tonne per year (MTY) as on 31.3.2016. A total of 52 washeries, both PSUs and Private, were operating in the country considering both Coking (29.69 MTY) and Non-Coking Coal (101.55 MTY).Coal Washeries in India Energy Portal

Subbituminous coals can lose 1.5% of their heating value. or at a high level ofThe coking coal resources can be augmented by recovering extra low ash coking coal from washery middlings by suitable beneficiation processes (Jha, 2012).This possibility has been established from tests. The middlings were crushed to 13 mm and 3 mm and thereafter subjected to float and sink tests. The results are presented in Figure 10.0 (a).COKING COAL BENEFICIATION Part 2 SciTech Connect
