Summary
Methods for measuring inter-chamber columns in development systems in mineral deposits are based primarily on extensive experience gained over the years in mining industry. As a result, the following two phenomena are observed: a deficiency in carrying capacity is detected after its entry into service, or the whole is resized.
The paper proposes practical as well as laboratory evaluation methods aimed at characterizing and defining the geomechanical state of the inter-chamber cells in the course of their work. A practically new classification method for quantification has been presented and tested, enabling the reaction of the inter-chamber cells and the subsequent state of the open spaces (chambers) around it to be predicted.
Keywords: inter-chamber cells, voltages, strength, measurements
