Evaluating the rate of reaching the assumed aim of any activity is the ground of verification of correctness of conduct assumed for its implementation. This evaluation is also the basis of verification of the algorithm of this conduct, including its modifying in order to reach the optimum state of the assumed goal. The procedures used for such an evaluation used to be described as a study of effectiveness of activities in question and its result directly as effectiveness. In case of technological processes, including the basic group of operations of mineral engineering, effectiveness is usually determined as a numerically expressed relation of really obtained process results to the results assumed, forecast or theoretically possible to be obtained. The variety of formulations of detailed assumptions of processes occurring in this discipline formulate the need of significant differentiation not only of the methods of evaluating its effectiveness but also precise determination of the very notion of effectiveness in the concrete conditions of implementation of the technological process. The work contains a discussion of this problem.
