PROCESS OF DEVELOPING POTASSIUM DEPOSIT WITH COMPLEX GEOLOGICAL AND MINING CONDITIONS

mining industry. SUBSTANCE: process is aimed at development of sylvinite formations with due account of nonuniformity of their geological feature. In agreement with geological prediction sections of mining field are opened by prospecting workings in which complex of geological-geophysical studies is conducted, physical and mechanical properties of enclosing rock are determined, then technologically uniform blocks in which quality of potassium ore, its thickness, physical and mechanical properties, properties and structure of water protection rock mass have close values are selected. After this direction and parameters of development workings and stopes are determined and in correspondence with them reserves in these blocks are developed. EFFECT: development of sylvinite formations.
