The lithological and geological structure in Buya strip mine is complex and the cranny is very developed

which leads to a lot of problems to the blasting. Based on the carefully observation on lithological structure and analysis on the act of prime

method of blasting and structure of detonator

it is concluded that blasting result is affected in many aspects. In this paper

the new blasting technique and blasting methods are put forward through many different blasting experiments in locale

which is much useful for solving such a kind of problem.
