Research on Mining Technology in Complicated and Steeply Inclined Coal Seam

Cai Yi

Abstract

The coal seam of Qingshan Coal Mine is complicated and steeply inclined coal seam,gas and grime popping out and the thickness of the coal change clearly.The caving technique for the complicated coal seam is different from the general coal seam.According to the practice of Qingshan Coal Mine,the caving technique in complicated and steeply inclined coal seam is introduced.
