When boarding the 9th level, the systems and elements of communication used with the outside will be explained (genephone, telephone, signalling panel, etc.), as well as the existing emergency equipment (stretcher, first aid kit, etc.), traction elements (winch) and the rail yard, as well as the electrical substation, the vacuum return circuit, and the ventilation control systems with doors and the dumping of materials through the earth raise.
After the above, the walk will begin to the areas where the coal has been mined. Along approximately two kilometres of galleries, the visitors will move northwards, where different water, air, communication, control, electricity and ventilation installations used in the mine may be observed; as well as the layout of the rail train, the mining support methods and the automatic system for opening the ventilation doors.
