To allow removal or replacement of mining equipment from a tunnel without unduly limiting the size of the mining equipment or without an unduly excessive cross-section of the tunnel, the mobile unit includes a conveying system having a first and a second transfer area, and a dust extraction system. The conveying system receives mined material in the first transfer area, conveys the received mined material to the second transfer area and dispenses the received and conveyed mined material at the second transfer area. The dust extraction system receives dust-laden air, extracts dust from the dust-laden air and discharges air from which dust is extracted. The mobile unit includes a first and/or a second dust collector for collecting dust-laden air from the first and/or second transfer area, respectively, with the first and/or second dust collector being arranged to supply the collected dust-laden air to the dust extraction system for dust extraction.

An intelligent automatic coal powder receiving device based on prevention and control of rock burst in coal mines includes a driving vehicle. Wheels with a moving function and a central processor are set on the driving vehicle, supporting mechanisms are set symmetrically on both sides of the driving vehicle, a coal powder storage box and a cross double frame positioning mechanism are set at the top of the driving vehicle, a coal powder receiving pipe is set on the cross double frame positioning mechanism, a binocular camera is set at the coal powder receiving pipe, and one end of the coal powder receiving pipe is a coal powder inlet, the other end of the coal powder receiving pipe is connected to the coal powder storage box through a connecting pipe, and the cross double frame positioning mechanism is connected to the driving vehicle through a telescopic mechanism.
