Mining produces three types of mineral commodities (metals, industrial minerals, and fuels) that all countries find essential for maintaining and improving their standards of living. Mining is a strategic industry because it provides critical needs in times of war or national emergency. Neither economy could not function without minerals nor the products made from them. In countries or regions where mining is concentrated, this industry plays an important role in the local economy. Mining faces nowadays major constraints due mainly to the scarcity of resources and its social and environmental impacts. Solving in a balanced way the conflict between positive effects on growth and development and the negative impacts on human being, communities and surrounding environment is the main driving factor towards technological improvement based on research and innovation

The “mechanized face” system will work in certain geologic-mining conditions. However, the analyze of these conditions is not limited to the establishing some concrete values for identified factors of influence, because this values would correspond only for a certain face field and in a certain position of the face line on the surface of this field. Moreover, even in the framework of the same face field, the factors of influence can record variations.
