Increasing the efficiency of rocks distribution tools in air-assisted well drilling

One of the main ways to ensure the normal temperature regimes of the rock crushing tool is to cool the temperature of the cleaning compressed air delivered to the well, that is, to eliminate the heat spread in the rock crushing tool by transferring the cooled air. However, the experience of drilling wells with compressed air shows that in order to effectively regulate the temperature regimes of the rock-breaking tool, it is necessary to provide optimal drilling regimes together with the cooling of the compressed air temperature.
