| Abstract: | In accordance with Bayanghe stock yard construction and geological conditions, making use of Pre-splitting blasting crack-theoretic, theoretical values of pre-splitting blasting parameters are calculated. Through field test, finally Large Aperture Wide space pre-splitting blasting parameters of Bayangbe stock yard are ascertained, half-cast factor is above 90%, improving the quality of construction projects, lowering the construction costs, getting a better economic efficiency. |
