To analyze the braking process of a mine diesel locomotive with hydrostatic-mechanical transmission (HSMT), a mathematical model has been developed. In contrast to available models, this one takes into consideration rules of changes in controlling the parameters of hydrostatic drive (HSD) and implementation methods for the braking process. Moreover, the model makes it possible to study changes in kinematic parameters, power parameters, and energy parameters of HSMT under various conditions of a mine diesel locomotive operation. It has been determined that the use of HSMT operating according to the "output differential" scheme is possible, providing kinematic disconnection of the engine from the driving wheels (for emergency braking with complete stop of the diesel locomotive) or at the expense of HSD while preserving the kinematic connection between the engine and the wheels (for deceleration). Use of the braking system together with HSD or the braking system only while preserving the kinematic connection between the engine and the wheels will result in HSMT failure.
