Abstract: Coal transporting trestle is one of the essential construction of coal enterprises. When the coal unloading through the hole at floor or wall of the coal transporting trestles, form the coal pile behind the bracket. And there is uneven coal pressure existing, causing deformation of the support structure. In order to ensure the continued safety should take some reliable measures for maintenance and reinforcement. In this paper, combining the force analysis of deformation of brackets with practical instances, obtain the structures. The conclusion is perhaps that take a design into quadrilateral, cylinder shaped, and oval tube structure can enhance the bearing capacity of the coal transporting trestles, serving as a reference for similar engineering design and reinforcement.
