We intend to use a 4 foot cubical faraday cage for microwave research. At this location, there is no safety earth available. What is the proven way to make proper earthing system?

Depends on what the cage is for. EMI testing, or HV testing, etc..
For EMI testing, you can cable over to a place where you can obtain a ground.
For high power RF, a cable should also be appropriate enough.

Good Luck! Rich
That relates to power, not a mere grounding of a cage being used as an RF shield/trap.
Why do you want an earthing system? Faraday cages work fine at any potential...
Be careful as to the design of that cage. Microwaves can "go thru" a sheet of metal; a good radar set running in a quonset hut can track birds flying by... Best use absorptive liners...
