Abstract: The shape of throw-blasting has an important influence on the total work quantity and cost of the stacking system, the parameter of the work-face design of the subsequent casting link, etc. Aiming at the current problems of insufficient sample size of the muck-pile shape and of the influence of incorrect data on the prediction effect, a standardized analysis and treatment method of muck-pile shape are put forward. The methods include the construction of muck-pile’s database, the selection and classification of the work-face shape characteristics, and the selection and classification of the muck-pile shape characteristics. It realizes the fast processing of massive muck-pile shape data. And it improves the effectiveness of samples. Finally, three groups of typical muck-pile shape curves with general interpretation significance are obtained by Lowess. The methods are fast, efficient and convenient, which provides an accurate basis for the design of the technology of throwing blasting and dragline casting in the open-mining.
