| Abstract: |
| The controlled blasting techniques is widely used in industry. According to the different way of blasting, it can be divided into control sector blasting, towns controlled blasting and special blasting. In recent years, with the development of global economy, more iron ore resources are needed, that promotes the upgrading of the iron ore price, some difficult margin angle mines become mineable. Blasting technology is the key to improve mining safety factor. In this paper, through blasting experimental comparison of the difficult mining body of Yu Hua Temple Mine, it comes to a conclusion that, the use of decoupling charge blasting is more suitable for difficult mining margin angle mines,. This experimental results with strong practicability and scientificity, has a certain guiding significance for similar mine orebody mining.
