Abstract
Relevance. The expenses for motor transport in the cost of coal mining reach 30-40%. Transportation conditions have a significant impact on resource consumption. In order to make timely and rational management decisions, it is nec-essary to use an operational, fairly simple, and correct assessment of the current state of conditions, as well as the determination of their target characteristics in tangible categories. These circumstances have determined the relevance of developing an appropriate methodology for assessing preparedness of conditions for motor transport. Objectives. The study is aimed at developing and testing methodological tools that provide for a prompt qualitative and quantitative assessment of transportation conditions for the following facilities: a dump, a main road, a face and a platform for shift change, at 4 quality levels. Methods Applied. The article describes used methods of systemic and structural-functional analysis, scientific generalization, expert assessments and industrial experiment. The use of the presented methods, and managers and specialists of the Solntsevsky Coal Mine contributed to developing a scale for assessing preparedness of transportation conditions, organizing a production experiment without failures in the existing production, conducting a step-by-step testing of the scale through an expert assessment of the conditions, performing a critical analysis of the preparation of operating conditions and developing measures for its efficient application. Originality. The paper presents the authors’ methodology for assessing preparedness of conditions at the opencast coal mine. Practical Relevance. Mastering of the proposed methodology contributes to determining the quality level of the operating conditions of dump trucks in a monitoring mode, using the appropriate 4-level scale, identifying reserves for improvements and outlining ways to use them with acceptable resource consumption. As soon as the methodology is mastered and skills in its application are gained to ensure the elimination of obvious deviations in the condition of all objects of transportation conditions, it is advisable to consider a transition to more accurate, but also more expensive instrumental methods of assessing conditions.
