By laying out 7~8 row mono-layer strip-shaped charges as principal charges and concentrated charges as auxiliary ones,the directional throw blasting is successfully achieved on the complex topographical and geological conditions,such as fow slope hill, thick overburden, fractured rock, three free surfaces,etc.Based on large-scale chamber blasting projecd practice,some practical experience on application of multi-row strip-shaped charges on complex topographical and geological conditions have been accumulated.
