A method for storing ecologically dangerous substances underground and an apparatus for accomplishing the method. These substances can be 
radioactive waste, spent fuel elements, nuclear warheads, weapons-grade 
uranium and 
plutonium, in all forms, as well as chemical weapons and many other toxic substances, including biologically dangerous substances. Also, this invention can be used for storing many other, 
specific storage objects, preferably particularly valuable metals, minerals and jewelry produced from same, as well as valuable papers, banknotes, archive contents and historical documents which are to be stored for a long time, etc. Storage takes place in a storage site having deep underground boreholes, by a special gas-hydrodynamic 
system and by 
remote control of all the necessary deep loading and unloading operations without using conventional mechanical loading and unloading devices such as shaft elevators, lifts and the like which substantially 
restrict the range of application of 
underground storage sites. Unauthorized access to the storage objects is excluded and nuclear and 
radiation safety is guaranteed in the storage of, for example, 
radioactive waste, spent fuel elements and also weapons-grade 
uranium and 
plutonium, as well as the safety of stocks of chemical weapons and / or their dangerous components as well as of many other toxic substances, and the 
fire safety of the 
underground storage zone and storage costs are reduced.
