| Abstract: | Based on the new concept of long wall with top coal caving with great mining height,several theoretical problems,such as parameters of working face,mechanism and cure of rib spalling,increase of recovery rate,bolting support in coal roadway with large cross-section,movement law of surrounding rock,and research on the special caving support,were discussed in order to improve the development of this technology. |
