Publication number: 20190186262Abstract: 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.Type: ApplicationFiled: August 31, 2016Publication date: June 20, 2019Inventors: Leonardo GONZALEZ, Egmont LAMMER, Erich BRANDL
