The article presents the construction and principle of operation of a unique instrument for determining the values of forces taking part in the cutting process (coal mining), which the author named POU-BW/01-WAP. It is the only instrument in the world which allows determining two components participating in the cutting process. The instrument has two measurement blocks, which are tensometric sensors of: the cutting force (Fs) and knife pressure force (Fd). These forces are recorded by means of a real mining knife applied in the drum-type longwall coal-cutter – tangential-rotary. Electrical devices of the POU-BW/01-WAP instrument include a set of elements for Coal Cutting Force Measurement (CCFM). The instrument has an ATEX certificate, enabling work in real conditions as a device intended for use in potentially explosive atmospheres – in compliance with directive 94/9/EC.
