Hydraulic Support Design for Extremely Thin Coal Seam

According to extremely thin coal seam geological conditions and hydraulic support design principles in Huangsha Mine, the paper applies the fuzzy mathematics and the optimization method to design the support type ZY3300/07/13 thin coal seam two-column hydraulic support. The determination of support type, the main form of support structure and support structural features are introduced in detail, and stress analysis of stent is described.
