Abstract
Rock salt solution contained in the salt cavern is pumped out, after which particulate solid waste materials are treated with dust suppressant agents to form free-flowing, non-dusting, readily usable mixtures, which are introduced into the cavern by trickling, or the salt cavern filled with rock salt solution is filled with a pumpable mixture of solid and liquid waste materials in such a way that the displaced volume of salt solution is pumped out and, after filling the cavern to about two thirds to three quarters of its volume, the water of the liquid phase is bound in the form of water of crystallization or as hydroxide or physically by adsorption through addition of hydrophilic compounds or substances as a means of solidifying it, and the cavern is then sealed.
