The effective production of high-quality 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 high-quality anthracite.

Six key steps were explored, including coal falling at the coalface, transport The coal rank varies from low volatile to high volatile bituminous coal. The gas content of coal seams ranges from to ft 3 /t.

Coal mining continues as an important economic activity today. Compared to wood fuels, coal yields a higher amount of energy per mass and can often be obtained in The caking characteristic of coal is the tendency of coal to melt together into a solid mass when rapidly heated.

The free swelling index (FSI) is reported on a scale of 1 to 9 in increments of 1/2.
