Comparing the results of physical modeling and full-scale experiment on ore face draw in the system of block caving for flat deposits. Izvestiya vysshikh uchebnykh zavedenii.

Introduction. The task of ore and host rock caving method effective parameters determination in the conditions of thick flat deposits is by no means trivial due to a lack of adequate international and local experience. Optimal parameters of ore draw are therefore best determined based on physical and mathematical modeling, taking into account the data of full-scale experiments.
Research aim. Based on physical and mathematical modeling and full-scale experiment data, the present research aims to identify the patterns of rock mass draw in the context of particular mining and geological conditions of a deposit. Using the obtained data on discharge figures formation kinematics, the research aims to determine the medium flowability indicators required to create a mathematical model of ore draw in similar conditions. Research methodology includes physical modeling of the ore face draw with of the medium extraction and flowability indicators determination.
Results. Comparison of full-scale experiments results with physical modeling results revealed sufficient convergence in the areas of losses and dilution, in the similarity of broken rock draw patterns, in the draw figure formation. Base on physical modeling, the dependence between the medium flowability indicator and the discharge figure height required to mathematically simulate the draw.
Summary. The medium flowability characteristics, defined during physical modeling and full-scale experiments and incorporated in the mathematical model of draw, will allow to optimize the parameters of the development systems with ore and host rocks caving at thick flat deposits.

Key words: flat deposits; system of development; block-caving; face draw; physical modeling; full-scale experiment.

Introduction. Lining technologies development is a way of improving the efficiency of field development as soon as technical and economic indicators of the whole excavation construction may vary significantly depending on how correctly the lining parameters are calculated. Mine lining at ore deposits in the conditions of dynamic manifestation of rock pressure is a field that requires additional research as far as mine stability improvement is concerned.
Research aim. As soon as excavation length may currently total tens of kilometers at one mine, the problem of implementing modern technologies of mine lining ensuring economic benefit for enterprises and personnel safety becomes more relevant.
Methodology. Promising methods of mine lining were analysed based on impulse excitation damping of dynamic stress waves at the contour of excavation. Results. The paper presents mining-geological and mine engineering aspects of Oktyabrsky deposit development. A description of the most common types of mine lining is given, such as shotcrete, bolting (anchor) with or without metal grid, metal pliable lining, monolithic. A number of anchor variants have been distinguished, allowing to significantly increase their bearing capacity: combined reinforced concrete anchor; hydraulic thrust tubular anchor; resin-grouted thrust anchor; reinforced concrete anchor with double cone contour lock; seismic resistant lining.
Summary. An analysis of innovative ways of securing mine workings has shown the promise of methods based on damping the impulse effect of dynamic stress waves on the contour of the workings with the help of multilayer supports, which include a special damping layer.

Key words: mine support; deposit; mine working; plot; efficiency.

Introduction. It is shown that the main executive mechanisms of the pit hydraulic excavator (mechanisms for turning the boom, turning the handle and turning the bucket) are hydro-mechanical units in which the engines (hydraulic cylinders) are an integral part of the lever-hydraulic mechanisms. Research aim is to improve the efficiency of hydraulic excavator operation. Research methodology. The presence of a kinematic connection between the engine (hydraulic cylinder rod) and the links of the lever-hydraulic mechanism determines certain relations between the parameters of the engine and the power parameters implemented on the driven link (boom, handle and bucket) – kinematic and dynamic transfer functions. On the basis of the main mechanisms functioning simulation model, expressions for definition of transfer functions are received. Results. It is established that there are rational values of the dynamic transfer functions of the main mechanisms at which the correspondence between the energy-power parameters realized at the driven links and the mode of loading of the driven links is achieved. Summary. Synthesis of design schemes of the main mechanisms with rational values of dynamic transfer functions will allow to exclude an overload of engines and, finally, to increase energy efficiency of hydraulic excavator functioning.

Key words: quarry hydraulic excavator; main executive mechanisms; kinematic and dynamic transfer functions of mechanisms.

Gornyi zhurnal = News of the Higher Institutions. Mining Journal. 2019; 7: 101–112. DOI: 10.21440/0536-1028- 2019-7-101-112

Object and aim of research. By eliminating coarse tailings, preconcentration may increase the content of valuable components in ore at the input of the processing plant with or without throughput reduction. The output of preconcentration tailings therefore determines the reduction level of operating costs. Technological and economic benefit may be significant with high prime cost of deep processing; it is connected with the costs of power-consuming processes of crushing, grinding, dewatering, as well as for reagents and material.
Research aims to study main technological factors which influence the effectiveness of ore preconcentration with X-ray fluorescence separation.
Methodology. The present research uses technological calculation of preconcentration with X-ray fluorescence separation (XRFS) at various granulometric characteristics of Run-of-Mine Ore and crushed ore, inhomogeneity analysis of components content in a lump with material size variation, experimental research on the study of sorted classes number influence on the indicators of separation with the use of XRFS in preconcentration technologies.
Results and the scope of results. Technological indicators of preconcentration with X-ray fluorescence separation are calculated for various granulometric characteristics of ore which comes to concentration. The obtained data allow to recommend XRFS in maximum size. The influence is revealed of the number of the sorted sorted classes on the total yield of preconcentration tailings. Maximum size of the concentrated material should be taken into account when choosing the number of sorted classes. Research results may be applied when developing the technologies of mineral raw material preconcentration with X-ray fluorescence separation.
Summary. The effectiveness of ore separating system operation is largely determined by the quality of ore preparation by granulometric composition both at actual mining (drilling and blasting operations) and crushing-screening at ore separating systems. The proposed approach allows to quantitatively estimate the influence of the number of sorted classes on the effectiveness of preconcentration with X-ray fluorescence separation and explain the choice of the number and the boundaries of sorted classes sizes.

Key words: preconcentration; X-ray fluorescence separation; ore sorting system; technology; inhomogeneity in a lump; granulometric characteristics; the number of the sorted classes.
