Introduction. In the future the development of underground ore mining is connected to mining transition to greater depths. In this regard the problem of improving the effectiveness of mining by means of reducing the use of cement at backfilling is rather relevant.
Research aim. The results of the scientific research are presented carried out with the purpose of investigating the conditions of applying the filling method of field development in various geological conditions with the account of ore bodies morphology, natural stresses field character, and lithologic inhomogeneity of the massif. Research methodology.
Research has been done with the account of the following provisions. The filling mass has been considered, firstly, as a geological structure bearing load under the influence of rock pressure, secondly, as a process structure saving the stope from possible rock caving and filling material 20 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 5. 2019 ISSN 0536-1028 caving and the related stoping procedural violations and ore mass impoverishment, as well as a means of eliminating voids in the rock massive.
Results analysis. Based on the acquired results the recommendations have been worked out concerning the conditions of applying the filling method of field development in various mining and geological conditions. In the conditions of flat and steeply pitching ore bodies with the thickness up to 10 m, the filling mass mainly functions as a geomechanical structure receiving load from the weight of rocks of the underworked massif, which significantly reduces the size and the speed of the underground massif subsidence. In these conditions the requirements to the strength of the filling mass are minimal; this widens the scope of weak filling. The use of the consolidating filling is recommended only in the conditions of “rockbump hazard” category. With steeply pitching ore bodies of low and medium thickness, as well as block and tabular ore bodies of any pitching type and high thickness, the scope of weak filling is limited mainly by the development systems with ascending mining of ore bodies.
Summary. Taking into account the great variety of geological conditions of ore deposits and the great choice of various technological variants of development systems it is necessary to be guided by the following. In the conditions of “rockbump safe” category and steep pitching of ore deposits it is necessary to give preference to the development systems with caving; and in the conditions of “rockbump hazard” category and the room and pillar mining, in order to increase the stability of temporary pillars and longterm maintenance of the undermined massif in the hard mode of loading, the mined-out space is recommended to be filled with the hydraulic filling.

Key words: development system; ore bodies morphology; field of stresses; rock pressure; filling mass; weak filling; rockbump

Formulation of the problem. A new variant of horizontal slicing system with hydraulic filling and descending extraction of ore under flexible overlap.
Research aims to investigate the possibility to mine steeply pitching ore bodies of low thickness with a horizontal slicing system with hydraulic filling and descending extraction of ore under flexible overlap.
Methodology. Laboratory and analytical researches have been carried out on the influence of the moisture content of backfill material on its stability, density, internal friction coefficient, and, finally, the size of load from the part of the backfill array on the flexible overlap.
Results. It has been stated that the developed method of slicing under the flexible overlap is structurally simple and usable at steeply pitching ore bodies of low thickness mining in rockbump hazardous conditions.
Summary. The proposed technology can be used to mine steeply pitching ore bodies of low thickness in rockbump hazardous conditions. The use of the technology will make it possible to increase the safety of stoping and stop using expensive and scarce material – cement.

Key words: horizontal slices; descending extraction; flexible overlap; hydraulic filling; physical modeling; curvilinear prism; moisture content of a massif.

Introduction. A number of studies have found that polyharmonic oscillations excited in the working bodies of vibrating machines can significantly intensify various technological processes. It is revealed that the more saturated the frequency spectrum of oscillations, the higher is the probability of occurrence of resonant movements of particles of the medium being processed.
Research aim is to study the nature of oscillations of the working body of a single-mass vibrator with Hooke’s joint in the transmission of an unbalanced vibration exciter, as well as to get an idea of the polyharmonic capabilities of such machines. Methodology includes the representation of vibrating machine working body motion mathematical model in the form the second order linear differential equation. A feature of the oscillating system is the effect on it of the exciting force of the centrifugal vibration exciter, which is driven by an electric motor through a cardan shaft. The solution of the problem was carried out by a numerical method with an original determination of the "almost-period" and the following frequency content of the oscillations of the working body.
Results. The non-periodic nature of oscillations is revealed, the method of investigating their frequency content based on the "almost-period" determination as the moment of phase trajectory "closure" is proposed and tested. According to the results of the study, the oscillation features of the vibrating machines with an inertial drive were revealed, their advantages and disadvantages were noted.
Conclusions. In the spectrum of the oscillation of the working body of the vibrating machine, harmonic components with close frequencies are dominant. To the considered scheme positive features, the global stability of the formed polyharmonic motion modes can be attributed.

Key words: vibrating machine; vibration exciter; Hooke’s joint; frequency content; "almost periodic"; polyharmonic.
