Wuda mining area in Inner Mongolia as the study area in this paper is located in northwest China.

Calculation of micro-structure parameter of Wuda bituminous coal and relationship-analysis between coal structure and coal spontaneous combustion;

Analysis of spontaneous combustion internal factors and division of spontaneous combustion types of coal seam in Wuda coalfield,Inner Mongolia;

Study on the fractures related with coalfield fire area in Wuda coalfield,Inner Mongolia

The fires in Wuda coalfield of Inner Mongolia is taken as an example to show the application of comprehensive assessment of environmental impact of coalfield fires.

Effect of the waste dump on environmental in Wuda mining area Inner Mongolia;

15,in the Wuda mining area,Inner Mongolia,indicated that the coal seams formed in a fluvial dominated delta plain are characterized by low pyrite content,high clay mineral content and better washability,but the coal seams formed in tide dominated delta plain are charac.

According to the analysis of occurrences of pyrite, clay mineral and organic sulfur in the main mined coal seam in Wuda coalfield, it can be seen that it is not practical to decrease the content of sulfur and ash in a single coal seam at present technical and economic condition.

Occurrence of organic sulfur in the hand picked vitrain samples from coal seams 9, 12 and 15 in Wuda coalfield, located on the western edge of Ordos Basin, was studied using the XPS technology.

Eight coal seam spontaneous combustion in Wuda coalfield, Inner Mongolia, were divided into 3 types from the viewpoint of internal factor control, viz.
