The effective production of highquality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of highquality anthracite. Six key steps were explored, including coal falling at the coalface, transport ...
