The Application of Pre-splitting Blasting near Slope Technique in Yuanjiacun Iron Mine
The Yuanjiacun iron mine is currently under the side-hill cutting,mining in the horizontal 1725 m of the eastern stope is about to reach the final mining Area.The pre-splitting blasting technique scheme should be used to sustain the slope stability.it is necessary to determine a pre-splitting blasting scheme suitable for the mine lithology.The suitable Hole network parameters,explosive payload,loaded constitution and network connection are determined by reference to the pre-splitting blasting parameter in homo-mining area in China and carrying out small scale targeted experiment near slope.By analyzing experimental effects and making specific improvement measures,the pre-splitting blasting reaches the expected effect.
