Abstract: In order to improve the single lane two-way traffic capacity of gentle slope inclined shaft and minimize the capital construction quantities of passing chambers, so as to maximize economic and technical benefits, it is necessary to reasonably solve the layout of passing chambers, especially the setting spacing of chambers. Based on the research results of previous technicians, this paper puts forward two formula models to calculate the setting spacing of the meeting chamber, and studies the section parameters of the meeting chamber. In view of the differences between the two formulas in calculation process and results, the two formulas are analyzed and compared from the aspects of calculation ideas, complexity and engineering practical application. It is considered that although the second formula model has the disadvantages of complex calculation process and high requirements for operation and management, it realizes the utilization of gentle slope inclined shaft to a greater extent, Reduce the capital construction quantities of meeting chamber. The design idea or license proposed in this paper provides reference for coal mine design and construction.

Key words: Slow slope inclined shaft, capacity, Meeting chamber, spacing, Formula.
