Deliverables Measurement and software system for blast control and blast design The System is made of: - A methodology for systematic and accurate assessment of blast geometry. - A software for the optimal blast pattern design, hole per hole. The method is based on a hole per hole blast pattern design in order to ensure an optimum adaptation of the explosive energy to the geometric variability of the rock mass. The adaptation of the explosive energy is done by searching for the best compromise between quantities of several available explosives. This takes into account differences in actual explosive power and also economic aspects. The local geometric conditions are assessed by appropriate measurements of the rock face and drilling deviations. One of the main characteristics of the method is the quickness for operation that allows to implement it continuously. This has been reached by means of efficient and user-friendly software as well as by optimised procedures for measurement that are required before each blast. Blasts that are designed and implemented in this way possess a homogeneous energy distribution over the whole rock-mass volume to be blasted. This ensures a more homogeneous fragmentation with fewer boulders and less fines. The variation of the specific energy level allows to influence the degree of fragmentation according to specific requirements. This energetic concept and its actual implementation are innovative compared to most current blasting practices. End-users of this result could be open-pit mines, quarries and blasting consultants. Neural Network system for fragmentation prediction The Prediction System for Blast Results is made of: - A Neural Network algorithm able to learn out of available data and to predict blast fragmentation. - A Software Tool linkable to any ODBC database. Its main characteristics are: - The Neural Network approach is fully in accordance with the continuous data acquisition methodology. - The system learns from collected data and is able to render information in the range of blasting practice. - The system can be linked to the database of the production control system. Additionally, the system also provides a blast orientated control system and a methodology for systematic and accurate assessment of blast geometry, a hole by hole pattern design as well as data management systems for production parameters either over time, or on a blast per blast basis.

The system includes acquisition, data organisation, and production analysis. It allows the continuous control of the production chain from drilling and blasting to primary crushing. All information can be organised on a blast per blast basis and thus allows analysing each single production chain. Consequently, it gives the possibility to control those primary chains (technically and economically) and subsequently to improve them. This represents its main specificity compared to other production monitoring systems. In terms of data monitoring the system is designed to be rather flexible, which allows the import of both automatically recorded data (from files) based on site specific import routines and to enter data manually directly into the Access database. The main characteristics of the production control system are: - It is specific to open-pit mining and the quarrying industry. - It allows to rebuild the primary production chain starting with blasting, which is often discontinuous and fuzzy for analysis. - It allows to control and analyse productivity of each single production chain starting with a blast. - It allows to improve productivity of each single production chain, by acting on blasting or other production parameters.
