What equipment does the rock drill propulsion device have

An underground rocket or rocket drill is a device for rapidly drilling holes through soil and rock of varying composition at rates up to 1 metre per second by utilising supersonic jets of hot gases. It was developed by Russian engineer Mikhail Tsiferov in 1948.Proposed uses for the device included drilling shallow holes for mineral exploration, construction, underground gasification of coal, water and methane drainage.The hydraulic rock drill consists of an impact part, a rotating part, and a water injection tank. The impact part includes a casing, a cylinder, an accumulator, a reversing element, an impact piston, and a buffer piston.
