1. DESIGN AND METHODS FOR MODELLING IN MINING

Traditional methods for designing and modeling of open pits and underground mines, are based on manual calculations of mining parameters and manual graphic interpretation of maps, contour surface mine, landfill, dump sites. The basis of this method is a long time for data processing and design of optimal solutions, which

significantly complicates the work.

IT enables faster, better and more creative work. IT applications in mining, allowed development of new methods for open pit designing and underground mines, which is significantly different from traditional methods. This methods was called the modern methods of design and modeling. The basic assumption for its application is that the adequate database of geological and mining data, as well as the model of the deposit must be formed. Modern methods for designing and modeling are based on the integration of IT with mining activities. In some countries, modern design and modeling methods have been used for thirty years, while in the South East and East Europe optimal pits designing is based on traditional methods. The main differences between traditional and modern methods of design are given in Table 1.

2. TYPES AND CHARACTERISTICS OF MINING COMPUTER PROGRAMS

The new IT are based on the latest achievements in the development of computer equipment, software, communications and satellite navigation technology ,robotics, artificial intelligence, measurement and control techniques, fuzzy logic and systems analysis. The essence of IT applications in the mining industry is reflected in linking the functions of planning, designing, monitoring, analysis, discussion and feedback control of activity through increased production, productivity, reliability, operational safety and operability. This concept of the work activity leads to utilization of information-management systems, multi-stage hierarchical logic, with the built in artificial intelligence, high supervision and control efficiency and developing a new generation of "intelligent" mining machines – robots (Vujić, 2010). 

Mining engineers have the opportunity to follow events in the production process from the command center and redirect orders and instructions for the execution of technological operations such as drilling, blasting, loading, transportation, mineral processing, waste disposal, etc.. The benefits of introducing IT into the mining are numerous (Vujić et al. 2008). Computer programs for defining and optimizing the open pit mine contour, landfill and production planning, are the basis for process control in the open pit mines design. There are currently many professional software packages, which include economic evaluation of open pit mine, the geology of the ore body, transport communications and other technological processes. Great number of other programs for general purpose are used in addition to specialized programs for surface mining.

Computer programs for design and modelling in mining 111 There is almost no surface mine where engineers do not use any of the computer programs to assist in the implementation of specific project solutions. Number of software packages manufacturers and experts for mining, is constantly growing (Savić, 2003). Modern computer programs use different methods as the basis for the development of applications, some of which are commonly applied methods Lerchsa-Grossman (LG), Floating Cone Method and dynamic programming. LG method has the lead over other methods of design. 

Computer programs that are used in mining, according to the purpose, can be divided into the following groups:

- general-purpose software packages: mining computer programs for modeling and design of mining deposits by the means of surface and in underground mining,

- specialized software packages for optimization of surface and/or underground mining exploitation and analysis of the metallic and non-metallic minerals exploitation and

- specific application software packages, designed for the analysis of specific problems related to the design of mines or the design of exploitation technology, for example: mining cost analysis, analysis of some technical problems in surface exploitation (for example: slope stability analysis), design of the system operation (drilling and blasting, truck transportation, loading and transport) and others.
