| Abstract: | The steep inclined seam is a difficult mining seam with a poor safety condition,a poor support stability,a lower mechanization and lower mining rate.According to those features of the thin and medium steep inclined seams,the paper proposed the improved direction and optimized method for the mining method of the thin and medium steep inclined seams.That is to say,with the increased length in strike,improved mining technology,improved gateway layout,optimized production system and others,the mining rate in th... |
| Keywords: | mining methods thin and medium seam steep inclined seam mining technology gateway layout method |
