Model study of bearing pressure on abandoned pillars (in the conditions of the Polar mine).

Abstract
When developing ore deposits in order to ensure the excavation of the richest part of the deposit in the first place or in case of simultaneous development by underground and open pit methods, it is often necessary to protect the overlying part of the deposit with artificial pillars made of concrete or combined pillars made of ore and concrete. The main purpose of such pillars, which determines the methodology of their calculation, is to ensure the stability of the overlying ore before its mining. A number of studies s are devoted to such calculations ...
