“…As a pre-stage of the dragline stripping technology, the effect of cast blasting plays a decisive role in the subsequent dragline stripping technology engineering succession and operation cost [37][38][39][40]. In order to ensure that the characteristics of the heaped-up bulk after cast blasting can meet the economic cost optimization of the subsequent dragline stripping technology, this paper needs to further study the subsequent dragline stripping technology and dissect the internal operation mechanism of the system as well as the logical relationship between operations on the basis of the surface of heaped-up bulk data acquisition and data fusion.…”

As the key technology of high-step stripping and blasting engineering, throwing blasting will be the development trend of the production optimization and benefit maximization of the open-pit mine in the future. In order to break with the research idea of optimizing the cast blasting effect by improving the effective throwing rate for a long period of time, maximizing the economic benefit of the subsequent dragline stripping technology and stabilizing the engineering connection, this paper takes the Heidaigou open-pit mine as the research object. Through data acquisition, analysis, and data fusion of the heaped-up bulk characteristics, the heaped-up bulk profile can be obtained to characterize the cast blasting effect. Secondly, the key factors influencing the cast blasting effect are determined based on the gray relational degree theory. Then, the black box principle of the system control theory is adopted as the guiding principle of the blasting optimization. Based on the production data of field cast blasting, the dynamic change law between the controllable variables of system input and the observable variables of system feedback in the black box system are studied and explored without consideration of the internal structure or the energy transformation relationship of the cast blasting system. Finally, the optimal blasting parameter combination under different working conditions is obtained. If the research results are successfully applied, it is expected that the dragline stripping technology cost of the Heidaigou open-pit mine can be reduced by 5~10%, and the results can also provide new ideas and new ways of optimizing the design of cast blasting.

“…Erdem and coworkers presented an extended bench model by means of which the optimal dragline selection may be made. 15 Hall et al 16 illustrated how reliability analysis can provide mine management with quantitative information of value for decision-making about surface mining equipment. Some researchers 1,17,18 have advocated the use of knowledge-based expert systems.…”
