1. A method of blocking cavings, post-mining caverns and mining excavations filled with water filling mixture containing fine-fraction materials characterized in that filled cavings, excavations or post-mining caverns are isolated with the use of stoppings made of materials insoluble in water, which stop fine-grained fractions of introduced filling, preferably porous fractions such as fine-grained furnace slag, fine-grained metallurgical discards, clean sand, finely crushed rocks with the thickness of stopping layer of at least 0.2 m, and the speed of medium flow through the stopping, depending on used material, should not exceed 2 cm/sec.
