Mechanized housing
Mechanized housing - repeated sets (sections) of the housing, spread in the subsurface between the ceiling and footwall which help at securing excavation, machinery, equipment and people. In addition, it serves to move the mining machine and the subwall coveyor along with the progress of the production of the wall.

Components of the housing section
Basic elements
The basic elements distinguish all of the housing necessary for its operation and transfer of force and load. These are:
- Stand,
- Girder,
- Floor runner,
- Cover infarcts,
- Connectors,
- Pins,
- The side panels.
The accessories
Accessories are all the elements necessary for proper working of the housing, but not carrying the loading of the rock mass. These include:
- Sliding system (stepping mechanism),
- Control and correction system,
- Piloting.
Additional elements
Additional elements, part of the housing, which are not necessary for its operation. These elements are:
- Elements of relief,
- Irrigation equipment,
- Lighting.
The meaning of the symbol of the housing
1. The manufacturer of the housing,
2. The minimum height of the housing,
3. The maximum height of the housing,
4. Housing type (P-the support, O-skirt),
5. The method of liquidation of the selected area for housing (z-boulder, p-Filling).
Housing FAZOS 12/28-Oz
Housing double-acting hydraulic curtain designed to work in the collapse system. Used in the walls with a height of 1.4 to 2.6 mi longitudinal inclination up to 25 °. It is used in difficult geological conditions for brittle ceiling, medium-concise and concise, and the increased pressures of the rock mass.
