【Abstract】 With the thickness changes of the No.2 seam of Shanxi Group in the Mowo mine field,characteristics of the mine field structure function and comparison analysis,the paper pointed out that the main factor to cause the changes of the seam thickness were the fault and the sliding between the layers.Base on the analysis the relationship between the seam thickness changes and structure function,the paper studied the thickness change law of the seams in coal mining operation in the mine filed.更多还原
