(1) Permanent equipment and facilities available during the construction period 1. The off-site projects available during the construction period include off-site roads, water supply, drainage, communication, 6kV transmission, substation engineering and hepatic field.
2. The on-site projects that can be used in the early stage of construction are dormitory, office, canteen, club, grease store, material warehouse, wood processing room, garage, machine repair plant, pressure blower room, etc. In the middle and late stages, the task can also be used to refer to the room, bathroom, lighting room, substation, gunpowder warehouse, boiler room and so on.
3. Available permanent structures include upper and lower water pipes, water towers or reservoirs, wall gates, well towers (or derricks), on-site lighting, and power line networks.
4. Available permanent equipment includes ground transmission and transformation equipment, pressure fans, hoists, underground power supply equipment, main drainage equipment and downhole hoists.
(B) the use of permanent buildings should pay attention to these issues 1. All use of permanent buildings and facilities design work needs to cooperate as much as possible, ahead of proposed construction plans, the construction unit in advance to arrange infrastructure projects; construction unit construction well prepared in advance. Under normal circumstances, the building (construction) to be used for construction shall be arranged for the construction of the mine during construction or later, for the construction of the well.
2. The use of permanent structures (structures) and equipment will inevitably increase the amount of work during well preparation, so this must be reasonably arranged. For permanent buildings that are available, single-seat dormitories should be arranged as early as possible. The remaining dormitories, offices, canteens, clubs and auxiliary workshops can be constructed in phases.
3. The design of permanent structures (structures) does not consider the needs of the well construction period. Therefore, the structural stress performance and structural characteristics during the well construction should be checked, and the necessary fashion should consider its reinforcement and transformation work. In order not to damage the permanent building (construction) and equipment, the construction unit should contact the construction unit and the design unit in advance to make overall consideration and take into account both.
4. When using the permanent facilities, the construction unit should maintain and maintain the permanent facilities to avoid abnormal wear; an effective management system should be established and a reasonable lease contract should be agreed with the construction unit.
5. The construction sequence of permanent buildings (structures), especially the buildings near the wellhead, should fully consider the space required for the construction of the mine, avoid cross-operation as much as possible, and reduce the conflict to the lowest point.
