The Research Of Underground Mine Blasting Cad System

Mine blasting is one of the main links in mine production. Blasting affects not only the follow-up production processes such as the shovel mining equipment, transportation and mechanical crushing efficiency, but also the overall economic efficiency. Blasting impact the safety of production. CAD and 3D modeling techniques have developed rapidly in recent years. Underground mine blasting CAD system which is used CAD and 3D modeling technology complete the two-dimensional and three-dimensional design of underground mine blasting and the complete the results predict. It is a perfect and practical system.A lot of topic was researched, such as the mine blasting program, blasting parameters selection, blast hole layout and graphics, blasting effect prediction and other scientific issues. By the Comprehensive use of underground mine blasting design principles, computer database technology and computer graphics technology. The underground mine blasting of computer-aided design have been achieved. This system consists of three functions:database management, the blasting CAD of blast hole lied in parallel and the blasting CAD of blast hole lied in fan. Database system can manage and maintain the data on rocks and explosives. In parallel blast hole CAD, System can help you lied blast hole in any plane and you can got two-dimensional chart and three-dimensional modeling of plane and blast hole. By the input of the blasting parameters, System can calculate the needed explosive weight, the volume of rocks which is blasted and dropped and three-dimensional modeling of rocks which is blasted and dropped. In Fan-shaped blast hole CAD, System can help you lied blast hole on any gallery and you can got two-dimensional chart and three-dimensional modeling of gallery and blast hole. By the input of the blasting parameters, System can calculate the needed explosive weight, the volume of rocks which is blasted and dropped and three-dimensional modeling of rocks which is blasted and dropped. The system not only realize the underground mining CAD, also innovate in blasting of 3d modeling and blasting effect prediction. By establishing the system of three-dimensional layer can establish internal and external three-dimensional structure of blast hole. Moreover, System considered a lot in geologic structure.The underground mining CAD system not only can simplify blasting design work, but also improve the accuracy of the blasting design data. The underground mining CAD system has greatly blasting practical value. It has a wide application prospect.
