The investigated object - periodic action tunnelling bunker-loaders. It is proposed to increase the mining operations efficiency by introducing an intermediate loading and transport element in a periodic action bunker-reloader form into the tunnelling machine - main transport technological chain, which ensures mining machine continuous operation while implementing the minimum time for loading a vehicle. It has been established that there is an experience in the bunker designs - loaders use with a traction-transporting body reciprocating movement: the transporting elements wedge-shaped or with variable geometry. To eliminate the identified shortcomings, fundamentally new technical solutions are proposed, based on a forward-acting hydraulic drive and transported elements use that provide material single movement in large volumes, at their movement low speeds. A proposed design detailed description protected by RF patents is given. The methodology general provisions for conducting experimental studies on a model setup are considered.
