Abstract: The article presents the results of theoretical and experimental studies of the conversional use of a rocket engine gas generator to create a device for thermal spallation drilling of solid rocks. The main difference between the studied device and traditional thermal drills is the relatively low temperature of the working fluid. It has been experimentally shown that this level of temperature of the working fluid provides a stable process of thermal spallation of the rock and at the same time a long life of the structure. The developed mathematical apparatus allows to select device parameters for various types of rocks. The concept of a jet drilling rig for drilling blast holes in open pit mines is proposed. This unit is mobile, does not require a heavy basement and preparation of the drilling site; it is charcterized with a high utilization factor and a long service life, and uses widely available components (air, water, kerosene, diesel fuel) as fuel components.
