Abstract The paper presents the possibilities of applying one of the multi-criteria assessment methods (the development measure method) in the processes of multi-variant design of technical and organizational solutions on the example of selecting equipment for a newly designed mine working in a hard coal mine. Using the case study, the authors proposed an alternative solution for decision-making problems in mining companies in relation to solutions based solely on unit costs of coal mining. The case study is preceded by the presentation of general principles regarding cost accounting in mining companies as well as the use of multi-criteria assessments.

The article discusses a case of security hazard in a longwall equipped with a properly selected chock shield support with two legs, technically efficient, introduced to the market and for operation in compliance with the requirements covering Polish hard coal mining. As a cause of the hazard an accidental coincidence was indicated, such as the occurrence of a tremor at an area with unfavourable geometry for the operation of the support section and leg (including the shift of the double-telescopic leg from the 1st to the 2nd hydraulic stage) at the time of the mining process. Immediate safety measures were applied successfully. They were aimed at minimizing the conditions dangerous to the crew. The section was withdrawn and spragged again. As a result, the leg operated in full extension mode of the 1st hydraulic stage, obtaining the required strength and geometry of the section and leg. The presented case study will be additionally supplemented in the future with selected analytical and bench tests.

The paper presents an analysis of selected aspects of motivation and engagement of hard coal mine employees working in longwall faces. The analysis of survey results covers selected questions from a broader survey conducted in the analyzed mining companies. The miners had a negative opinion on the incentive programme in their workplaces, stating that it is ineffective. The survey also included factors affecting the engagement of the entire research sample in their work, showing their significance level for the respondents.

Water probe in coal mine working face is an important part of the work of Mine Water. When the mine working face close to the aquifer hydraulic conductivity faults, underground rivers, caves and hydraulic conductivity collapse columns; extractive damaging effects, water probe should be done. However, the calculation of water inflow face probe has no feasible way. This paper discussed the theoretical calculations to explore water drilling inflow well group interference method and provides the basis for provision of drainage system for the coal mining enterprises.
