blasting
Pre-production (construction, commissioning, and start up):
■ Site preparation
■ Construction of sediment ponds and site drainage features (ditches, ponds, site diversion channels, re-grading). Sediment ponds will be constructed around waste dumps, pit footprints, along access ways and where facilities are located to control sediment run-off.
■ Construction of the main haul roads
■ Construction of an access road
■ Construction of the stockpiling area.
■ Stripping of the pit area,
■ Removal of the laterite cap and pre-stripping of waste
■ Construction of the process plant, water treatment facilities, power plant and supporting infrastructure.
■ Commissioning and start-up of process plant
■ Construction of the underground box cut and decline and associated infrastructure
■ Construction of the mining surface infrastructure of the open pit and underground including explosive magazine and explosive supplier infrastructure.
■ Establishment of a portal, forcing ventilation development fan.
■ Installation of a generator for initial development.
■ Set up underground substation.
■ Installation of air compressor.
■ underground development works.

ventilateur de soufflage en phase développement
'Development' is the 'access' phase of a mining (underground) operation. It is preceded by exploration and followed by the production/extraction phase.
DEVELOPMENT
Overview
The term "development" is normally used to refer to the drivage of all first workings roadways, whether main roadways or setting–out pillar areas ready for secondary extraction. Development in most mines is carried out by a number of separate development "units" each consisting of a full set of equipment (coal cutting machine, face transport equipment for coal and materials, roof support equipment and ventilation equipment) usually manned by more or less fixed crews on each shift. It is common for several such units to be operating more or less independently at several locations to support one or more longwall panels. In some mines however which do not operate longwall equipment, a development unit may become the secondary extraction unit having completed the first workings for a panel.
[ …] Development Face Ventilation
To maintain a ventilation circuit it is necessary to have an intake and a return airway to the innermost point to be ventilated. As roadways are mined, the last section has only a single roadway so another arrangement has to be made.

'Forcing' means that air is blown into the workings by means of ventilateurs de soufflage. Extraction fans work the other way.
In your expression 'forcing ventilation development fan', 'ventilation' is redundant since that is what fans do.
So I think you're looking at something like ventilateur de soufflage en phase développement. Whether this differs from a 'forcing ventilation production fan' I cannot say. Maybe the latter is more powerful, since it stands to reason that there will be more machines at work in the mine during the production phase than during the development phase.
