The analysis of the reasons of failures of building designs of conveyor galleries in the conditions of long operation
Abstract: On the basis of the given aprioristic sources the analysis of the reasons of troubles of building designs of conveyor passageways is made. It is established that in the conditions of long operation troubles of conveyor passageways with superstructures executed of trusses are most often observed. As a rule, troubles occur owing to destruction of elements of a connecting lattice near to basic knots, and also owing to destruction of assembly joints of bottom flanges of trusses of superstructures. Destruction of central welded joints is caused by influence of following factors: local impact sredne- and strongly-corrosive corrosion environments; dynamic character of technological and emergency loadings; the unsuccessful constructive form of designs of superstructures. Destruction of elements of a connecting lattice of superstructures results from a local corrosive attack near to floorings in the conditions of strongly corrosive corrosion environment which is formed owing to a hydrowashing down of a coal dust and a prorash.
Keywords: troubles of building designs, conveyor passageways, operation factors, the reasons of troubles.
