| 1 | Analysis of predictor equations for determining the blast-induced vibration in rock blasting显示文摘The paper proposes a new empirical correlation designed to complement the‘‘site laws'currently used to evaluate the attenuation in the rock masses of vibrations induced by rock blasting.The formula contains a deformed exponential known as the K-exponential,which seems to well represent a large number of both natural and artificial phenomena ranging from astrophysics to quantum mechanics,with some extension in the field of economics and finance.Experimental validation of the formula was performed via the analysis of vibration data covering a number of case studies,which differed in terms of both operation and rock type.A total of 12 experimental cases were analysed and the proposed formulation exhibited a good performance in 11 of them.In particular,the proposed law,which was built using blast test data,produced very good approximations of the points representing the vibration measurements and would thus be useful in organising production blasts.However,the developed formula was found to work less well when a correlation obtained for a given site was applied to another presenting similar types of rocks and operations,and thus should not be employed in the absence of measurements from test data. | Marilena Cardu Dario Coragliotto Pierpaolo Oreste | 2019 | International Journal of Mining Science and Technology2019，29，6： | 4 |
| 2 | Complexity analysis of blast-induced vibrations in underground mining: A case study显示文摘Blasting in geological bodies is an industrial process acting in an environment characterized by high uncertainties (natural joints, faults, voids, abrupt structural changes), which are transposed into the process parameters (e.g. energetic transfer to rock mass, hole deviations, misfires, vibrations, fly-rock, etc.). The approach to this problem searching for the 'optimum' result can be ineffective. The geological environment is marked out by too many uncertainties, to have an 'optimum' suitable to different applications. Researching for 'Robustness' in a blast design gives rise to much more efficiency. Robustness is the capability of the system to behave constantly under varying conditions, without leading to unexpected results. Since the geology varies from site to site, setting a robust method can grant better results in varying environments, lowering the costs and increasing benefits and safety. Complexity Analysis (C.A.) is an innovative approach to systems. C.A. allows analyzing the Complexity of the Blast System and the criticality of each variable (drilling, charging and initiation parameters). The lower is the complexity, the more robust is the system, and the lower is the possibility of unexpected results. The paper presents the results obtained thanks to the C.A. approach in an underground gypsum quarry (Italy), exploited by conventional rooms and pillars method by drilling and blasting. The application of C.A. led to a reliable solution to reduce the charge per delay, hence reducing the impact of ground vibration on the surrounding structures. The analysis of the correlation degree between the variables allowed recognizing empirical laws as well. | Cardu Marilena Dompieri Mauricio Seccatore Jacopo | 2012 | International Journal of Mining Science and Technology2012，22，1： | 3 |
