Increasing the safety of formation automotive dumps on quarry

the article concerns a described mechanized complex for dump of rock delivered by the tip-lorry to the heap with subsequent compaction of the waste space surface. The use of this mechanized complex allows to increase the work safety during dumping and reduce the expensive equipment fleet used for these purposes. It is proposed to fill the dump with the help of a self-propelled vibration dumper. The construction of a self-propelled vibration dumper is based on a vibration-transporting device with two self-synchronizing unbalanced vibration exciters. The compaction is carried out by a self-propelled vibration device for forming a stable dump mass that implements the compaction mode in a limited space by a function vibration element with a polyharmonic oscillations. The relations of the structural and dynamic parameters of vibration transporters are obtained by the method of physical modeling and ensuring the stability of the synchronous mode of vibration sources. The findings of field tests are presented in conclusion.
