| Abstract: | Blasting methods of traditional excavation are introduced at Jinshan gold mine.The blasting hole arrangement of hard ductility rocks in the roadway excavation is discussed and explosive loading coefficient is determined.The efficiency of roadway excavation of hard ductility rocks and the blasting result are raised by the test,for example,in creasing hollow sumping cuts,reducing number of explosive loading blasting holes,raising explsive loading coefficient and so on. |

| Keywords: | roadway excavation hard ductility rocks blasting hole arrangement explosive loading coefficient |
