Abstract: The purpose of the initial step from this paper is not to reflect to the opportunity of the implementation of some new methods of analyze and to offer the possibility to fundament some strategic decisions regarding the improvement of the abilities from the pit coal market, following that by applying creatively a model of analyze to be assured a board picture, with a role of offering basic information for taking the major decisions regarding the decrease of the coasts and increase of the activity efficiency in order to perfect the actions for reconfiguring the speed for extracting the pit coal. To apply a model of stimulation having as base the correlation analyze, which surprises the influence of some factors as: goods production, valour productivity of the work, the ponder of material expenses into the total cost over a factor of performance represented by the expense at 1000 Lei of goods production allowed the visualization of the changing the factor resulted into the conditions of the increasing or decreasing of the studied factors. The value of the determination coefficient and the result of using the Fisher test show us that the model expresses very well the link between the expenses at 1000 Lei of goods production and the mentioned factors, the reason for which it can be used at setting the decisions, for improving the organization and managing, having as purpose to increase the work quality (based on the productivity increase) and reducing the expenses for exploiting the hard coal.
