The main task of this work was the protection against collision between the boom and the stock pile, as well as other equipment, in open pit mining. A further task was the exact representation of the functionality of all the sensors used for the machines working in open pit mining as well as in underground mining. Three specific sensor technologies were available for collision protection, namely the principles of ultrasonic, microwave and laser. After studying the advantages and disadvantages of these three sensor types and after carrying out several trials of a laser measuring system, it was found that the laser sensor was the most suitable. Although this is not appropriate for any and every case, it could still be shown that it has important advantages compared to other devices. The measurement characteristics of the laser measurement sensors were determined using various conditions of operations. In this way it was possible, in the scope of this work, to make a clear recommendation for the use of such an LMS system for the future applications of the company Sandvik.
