Decreasing the load of next slice entryway in thick seam by relieving method |
| |
| Abstract: | The paper introduces the design theory of relieving method on entryway and indicates that driving a relieving way can protect the entryway of next slice from being destroyed in longwall top coal caving mining. It also presents the parameters and the problems to be taken good care of when a relieving way is extracted. |
