The Blast Maker program-technical complex is a science intensive product combining information-analytical software and technical facilities for the acquiring, processing and transmitting of data about rock massif properties directly from drilling rig during the drilling of blastholes. The Blast Maker enables to design drilling-and-blasting with optimum parameters and to achieve the high quality of rock crushing

Drilling and blasting (D&B) is the main method of rock breaking in the exploitation of mineral wealth in open pits. D&B design is a laborious process that requires high precision, operability in calculations and the preparation of necessary documentation. The heterogeneity of rock strength properties remains the main factor that complicates the design of blasting and the achievement of even rock mass crushing. Geological exploration generally cannot provide sufficiently complete information, as the grid pitch of exploratory holes is too large. Therefore, in the absence of real data about zoning of open-pit field, designers usually increase drilling and explosives consumption by 20-25% on the average at breaking massifs with complex structure.
One of the effective ways to obtain necessary data about massif strength properties is to use the information acquired during the drilling of the block to be blasted by drilling rigs. This approach is attractive primarily because it does not break the existing operating regime in open-pit and does not require expenses on performing additional geophysical works to obtain detailed data about the properties of the block to be blasted.
The Blast Maker program-technical complex is a practical realization of this approach implemented using cutting-edge technologies in microprocessor engineering and programming. The program module is based on sophisticated physical and mathematical models. At the same time, the shell program of the complex is adapted to Windows environment and has a user-friendly interface.
In computer-aided design the system provides the optimal placing of boreholes, which takes account of block geometry and rock properties, and models the charge structure for the more effective distribution of blast energy. Automated workplace of drilling-and-blasting design engineer makes it possible to consider all details of technological process.
The digital model of deposit constitutes the information base of the whole Blast Maker system. In contrast to the existing models, this one is the dynamic database of, for instance, physical-mechanical properties, which is permanently complemented with data from drilling rig. At that, the program has built-in algorithms of inter- and extrapolation allowing the automatic forecasting of the parameters of the contiguous items of the digital model. The continuous maintenance of the digital model ensures increased information validity. Apart from data about the content of mineral, the digital model also accumulates the main technological and physical-mechanical properties of rock massif enabling to make the higher quality designs of technological processes, including drilling-and-blasting.
The digital model of deposit is closely connected with the system of the geometric visualization of open-pit field and mining-geometrical analysis. This system allows planning mining works taking into account the location of ore body, designing transport communications, determining the scope of daylighting, visual presenting of open-pit surfaces in various scales and perspectives and editing 3-D images.
The system of the acquiring of data from drilling rigs is based on the methodology of determining massif strength characteristics using the data about the power intensity of drilling. The specific energy of drilling is one of the successful energy indexes. It depends on bit weight, borehole section, bit speed, bit turning moment, penetration rate and drilling rig vibration. Basing on these parameters, one can monitor the technological rock properties and identify rocks and large cavities. The system has equipment to register drilling parameters with the subsequent determination of rock strength properties. The equipment is intended for functioning in the broad range of climatic and operating conditions, it meets the temperature limits from -40 C to +50 C, it withstands the high level of vibration and has a dust- and moisture-proof case. All data from drilling rigs is transferred online via radio channels to the computer installed at control station or administrative center. All parameters are reviewed altogether at the central station and filtered through appropriate algorithms. At the same time, the parameters measured in the process of drilling reflect not only rock properties, but also the state of drilling tool.
The Blast Maker program-technical complex has many housekeeping functions. A design engineer can easily and rather quickly predict the results of explosion in accordance with selected project parameters. The forecast is visually represented in 3-D image form. Any number of boreholes, including slant holes, can be added or removed. The system also includes economic calculations that allow choosing the type of explosives and rational charge structure. During a short period of time, the designer can review various blast design variants and choose the most optimal one. The output documents module generates all necessary views and formats.
Thus, the Blast Maker program-technical complex is the most comprehensive solution of the task of optimal design of drilling-and-blasting in mining companie's open pits without changing the adopted technology of performing drilling-and-blasting. The full-scale introduction of the system will enable not only to significantly decrease drilling-and-blasting costs but also to increase the quality of drilling-and-blasting as well as the operability of the management of facilities and processes in open pit. The completeness of information about all past designed and performed blasts, the drilling parameters and techniques of all drilled holes gives real opportunity for the adaptive control of drilling-and-blasting.
