ANALYSIS OF METHODS FOR BACKFILLING MINING DURING UNDERGROUND EXCAVATION OF POTASH ORES

Abstract

The paper presents the problems of developing potash ores during underground mining and characterizes the method of hydraulic backfilling in potash deposits. The filling of mined-out space allows for solving the problems of maintaining the earth's surface, preserving farmland taken for waste storage, and preventing the salinization of fresh ground and surface waters with excess brines
