ABSTRACT: The working time of a single mine surveyor or the working time of a whole “Mine Surveying Ergatic System” (MSES) depends on various factors. These factors are: different qualities of a surveyor as a professional and a person, his emotion and attention, accuracy and comfort of mine surveying instruments, and the mine working environment. These factors make it possible to conclude the MSES working time to be a stochastic quality. In our research, a unimodal alpha-distribution was used. We have studied the working time of 1 type of MSES: “measurements of horizontal angle”. More than 80 mine surveyors and students have taken part in the experiments. The alpha-graphic line shows an accurate interpretation of different points, so it may be used in testing mine surveyors’ professional skills.
