PRACTICE OF USING THE CHAMBER AND PILLAR MINING SYSTEMS IN EXTRACTING SMALL ORE BODIES AT THE KOCHBULAK MINING DEPOSIT WITH UNBALANCED MINERALIZATION
The paper presents details about the experience of using the chamber and pillar mining system in small ore bodies mining with irregular mineralization in the Kochbulak gold mining deposit. The article includes a short description of the geological and mining conditions of the deposit and provides information on the development systems used for ore bodies extraction having different mining and geological properties. It refers to the conditions in which it is possible to apply the chamber-and-pillar development systems. The essence of the system, the procedure of ore bodies mining, the main features of it, its advantages and material disadvantages are also noted. It also summarizes the findings of the research carried out in the Kochbulak mine. The purpose of the study was to increase extraction indicators without the cost of ore going up.
