Resumen

This article sought to carry out an experimental study for the optimization of fragmentation through the implementation of a rubber plug to apply the air chambers technique; For this, based on past research, the best position of the accessory and the length of the air chamber that provide the best results in the size of the fragment were also identified. The tests were carried out in an open pit mine, with proven geological and geomechanical characteristics and calculated in geomechanical laboratory tests by compression and tensile tests. There were 3 proposals for the position of the air chamber accessory with the determination of the corresponding length. After the blasting process, the comparative granulometry measurements of the proposal were made versus the granulometry obtained without the application of the accessory, for which the use of an image analysis software was proposed to determine a P80 of fragments passing through said mesh. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.
