Annotation: In the article there are given the results of theoretical research of dynamic characteristics influence of head frames constructions on the special load because of lift parameters rope break. On the basis of mathematical design of dynamic interaction of head frame constructions with a lift machine while rising vessel gamming, the degree of forces influence of buildings mass on the size of main vector load has been set. For large lift machines, and extreme values of emergence load the dynamics coefficient is 1,05-1,1. For the lift mine settings equipped with small lift machines, the case, when the lift rope break is in possible, the coefficient of dynamics is 1.2-1.3. While designing of head frames it is necessary to take into the consideration the dynamic nature of lift rope loads. Especially the significant influence of forces inertia on the stressed deformed state of mine head frames constructions with placing of directive sheaves on the same level for oscillation of torsion forms in this case the dynamic coefficient are 1.3 – 1.6.
Keywords: head frame, loadings of emergencies, calculation of build constructions, coefficients of dynamic quality.
