The MB 900 CM shearer and heading machine is designed for safe mining and mining in mines with the risk of explosion of gas and dust. Heading and mining in the required corridor profile is provided by a set of cutting organs. The excavated rock from the shearer can be removed by self-propelled shuttle cars or using belt conveyors.

The shearer consists of a main cutting organ, a cutting organ for extraction and adjustment of the ceiling space, a cutting organ for extraction and alignment of the corridor bottom, including the undercut of corner edges of the corridor, a scraper conveyor for the transport of the extracted material, a belt chassis for moving of the entire shearer at the working and manoeuvring speed (up to 10 m / min). The rear part of the scraper conveyor is oscillating both vertically and horizontally.
