Judgment and evaluation system of 3D-suface blasting based on GIS

Blasting occupy an important position in exploitation of mineral resources. With the development of mining and Geographical Information System (GIS) in mining industry, Digital Mining (DM) and Digital Blasting are becoming the research focus and they will be an inevitable trend in the future. In order to evaluate the incidental influence caused by blasting and accomplish the simulation, a blasting predicting and evaluating model supported by digital elevation model and remote sensing image is proposed. This model using three-dimensional display and spatial analysis ability of GIS accomplishes several functions, such as the simulation of blast hole, analysis and evaluation of blasting vibration, air-overpressure and optimal transportation route calculation. The system named 3D-Blasting Information and Judgment System (3D-BIJS) can be used to predict mine after blast and help the decision-maker to guide the practical production.
