Surface Mine Blast Design and Consultant System
نویسنده
چکیده
A computer-aided blast design collsultanL system has been developed. The software consists of two modules: one uses theoretical and empirical formulae and procedures to design a blast based on user supplied geological Hnd mechanical data, while the other is an expert syslem that analY7.es blast vibration problems and recom mends remedial action using k.nowledge based rules. The system is currently undergoing field eva luation.

OPTIMAL WIND RESISTANT DESIGN OF TALL BUILDINGS UTILIZING MINE BLAST ALGORITHM
Practical design of tall frame-tube and diagrids are formulated as two discrete optimization problems searching for minimal weight undercodified constraints under gravitational and wind loading due to Iranian codes of practice for steel structures (Part 6 & Part 10). Particular encoding of design vector is proposed to efficiently handle both problems leading to minimal search space. Two types o...
متن کاملBlast Design for Improved Productivity using a Modified Available Energy Method
In this work, a new drilling and blasting design methodology is introduced and applied at a case study mine to improve productivity. For the case study copper mine, a blast diameter of 203 mm is proposed to be used in the ore zone to meet the new required production rate of 90mtpa from 75mtpa. Currently, the Konya and Walter’s model is used to generate drilling and blasting design at a bl...
متن کاملEffects of Blast Vibration on Unplanned Dilution in an Underground Metal Mine
One of the factors affecting overbreak or slough of the roof and walls of underground stopes, causing unplanned dilution is blast vibration. The amount of damage caused by earth vibration can be measured in terms of peak particle velocity (PPV). In this study, in order to investigate the effects of blast vibration on the occurrence of unplanned dilution, 72 three-component records acquired upon...
متن کاملOptimisation of Fragmentation and Comminution at Boliden Mineral, Aitik Operation
The objective of this thesis is to optimise the fragmentation at Boliden Minerals open pit mine Aitik. Blasting is one of the main operations in mining, and its performance has a major impact on the overall economy of the mine. The fragmentation process affects not only the local productivity and unit costs of the mining department. It also affects the performance of the subsequent comminution ...
متن کاملA comparison between effects of earthquake and blasting on stability of mine slopes: a case study of Chadormalu open-pit mine
Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...
