Coal and coal miningModeling study on the influence of the strip filling

As coal becomes buried more deeply it goes through a sequence of changes in rank from peat to lignite sub bituminous coal bituminous coal semi anthracite and anthracite This process results in irreversible changes in the chemical and physical nature of the coal and there can be considerable variation within a coalfieldThe method of first filling and then mining could greatly reduce the stress concentration and plastic zone during the mining process In summary mining scheme 2 filling before mining can avoid the formation of isolated island coal pillars in the process of mining and without considering other factors scheme 2 should be adopted as much as possible
