Blasting Technology for Collapse of Open-pit Mine Goaf
During the excavation process of open-pit mines,a large number of goaf are formed.Due to the special nature of goaf,they have a certain impact on the normal mining operations of the mine.If not handled properly,it is easy to cause safety accidents such as goaf collapse.Therefore,in the production of open-pit mines,it is particularly necessary to increase the research efforts on collapse blasting technology in goaf.Based on this,taking A open-pit mining area as the research object,this paper discussed the collapse blasting technology in the goaf of open-pit mines from three aspects:step blasting mechanism,optimization of goaf blasting parameters,and determination of blasting scheme,in order to help improve the production safety of open-pit mines.
