Explosive technique of top coal caving in roadways of medium-thickness and high-thickness steep seam |
| |
| Abstract: | The method of top coal caving in roadways is a new mining technology used in medium-thickness and high-thickness steep seams. The technique of primary drilling and blasting is an effective way to solve the problem of crushing, caving and transportation. Author introduces the primary drilling and blasting parameters and their applications in many test mines and provides the experience of this new mining method |
