For the extraction of non-metallic building materials currently used as a surface and underground mining. However, the proportion of an surface geotechnology significantly more than the underground. The methodical approach of defining pillars of rational parameters when mining deposits of non-metallic building materials geotechnology underground room and pillar systems.The analysis of a set of fundamental theories of natural balance.Adjusted formula of calculation the optimum width for the conditions room-and-pillar mining of non-metallic building materials.Simulation results of pressure occurs in the room-and-pillar with a load in the program Autodesk Inventor Professional 2013, which is based on the method of finite elements. The analysis of the simulation data shows that in the considered geological conditions, the stability pillar remains within acceptable for safe conduct of sewage mining.
