Abstract: Abstract: Based on the analysis of the auxiliary transportation conditions, the auxiliary transportation modes and main technical parameters were put forward for Xizhuo mine，a typical mine soft coal seam in Weibei. According to the present situation of mine construction, the technical advantages and disadvantages of the auxiliary transport mode were analyzed and demonstrated, and then the construction investment and operation cost were estimated and compared. After that, the monorail crane was determined as the auxiliary transport mode of mine.On this basis, through the calculation of operational parameters, monorail crane vehicles and track system were designed and selected. According to the layout of the roadway in the panel area, the location and design parameters of the monorail hanging chamber were determined.
