Software Systems Application for Shafts Strength Analysis in Mechanical Engineering

Surface mining and open pits engineering affect the environment in a very negative way. Among other pollutions that open pits make during mineral deposits exploiting, particular problem is the landscape changing. Along with converting the land into pits, surface mining is connected with pilling dumps that occupy large ground. The article describes an analysis of transportless methods of several coal seams strata surface mining, applied for open pits of South Kuzbass coal enterprises (Western Siberia, Russia). To improve land-use management of open pit mining enterprises, the characteristics of transportless technological schemes for several coal seams strata surface mining are highlighted and observed. These characteristics help to systematize transportless open mining technologies using common criteria that characterize structure of the bottom part of a strata and internal dumping schemes. The schemes of transportless systems of coal strata surface mining implemented in South Kuzbass are given.

Rational Use of Land Resource During the Implementation of Transportless System of Coal Strata Surface Mining

Higher education modernization in the CIS countries takes place under the conditions of dynamic changes in economy and society. These changes are determined by the social and economic development of the country and the world globalization processes - cross-border intercultural communication, knowledge transparency, and the establishment of information society. Educational globalization is a continuous process of creating a unified global educational system, in which the distinctions between its member educational systems are being blended.

Innovative Technics of Managing Engineers’ Global Competencies

Substantiation of characteristic bending points of the blade operating body of the geokhod

Within the rent-and-raw material model of Russian economy the state’s attempts to stimulate import substitution do not generate innovative type of economic development and rebuilding of its industrial sector, competitiveness on the domestic market. In high entropy of market processes it becomes obvious that without recovery of effective global production chains in Russian economy the risks of economic and geopolitical security of Russia, the final loss of Russian technological identity, the loss of international competitiveness and securing raw material vector of long-term social and economic development are increasing. Therefore, it is machine building, as an industry, being a member of most production chains must become a driver of import substitution. Innovative development of machine building is especially in demand in such industrialized region as Kuzbass. Its major industries – coal, metallurgical, chemical - are in need of machinery products. The article describes the features and tools of machine building innovative development.

The innovative development of machine building as a driver of import substitution

The work describes the features of process of mine working with application of geo-walkers, defines a number of tasks for determination of parameters of an external propulsor and proves their urgency

Justification of Creation of an External Propulsor for Multipurpose Shield-Type Heading Machine – GEO-WALKER

the effect of distance between ledges on the stresses in the rock of the face and distance between ledges as a function of the distance to the axis of a working are described, presence of a critical ratio of distance between ledges to the thickness of cut layer and the features characterizing the central area of the face are revealed.

The Influence of Relative Distance between Ledges on the Stress-Strain State of the Rock at a Face

The features of initiation of irregularity of rotation in geohod transmission with hydraulic cylinders in different phases are discussed in the present study. The procedure for determination of torque variation, as well as the effect of transmission parameters on the value of variation is described

Estimation of Torque Variation of Geohod Transmission with Hydraulic Drive

The paper presents a calculation of the roller minimum length based on the contact stresses at work on the transfer roller surface and separator.

Determination of Parameters of Roller of Wave Transmission with Intermediate Rolling Bodies with Hollow Shaft for Geokhod

Influence of geometrical parameters of generatrix of helicoid on a guide of geokhod bar working body is proved in article. The relevance of the conducted research is considered and proved. General characteristics of the geokhod are presented. Features of geokhod working body, in particular formation of irregular shape of a surface of a face and working body are formulated and also it is told that at screw movement of geokhod working body of a face, points of working body will be formed a helicoid (screw) surface of a face. For establishing of die goals and objectives of research general geometrical parameters of generatrix is marked and justified which treat length of generatrix, width of generatrix of helicoid. pitch of hehcoid and it's form. Forms of guides of geokhod bar working body based on basis parameters of geokhod and accepted general geometrical parameters of geokhod working body are received and presented. In virtue of the conducted research the dependence of a form of a guide of bar on general geometrical parameters of helicoid is defined and also basis parameters of hehcoid in influencing a form of guide of working body.
