Social Media as the Form of Being and Social Institute
The multiuser sites, which are constructed on web 2.0 technology and forming a special type of social
networks, unite a huge part of mankind at present. Social networks are understood as alternative form
of being, namely existence in communications and as the integration social institute, which takes up
other social generality and realizes their key functions. From the point of view of the author, as the form
of being social networks are degression, the embodiment of real and individual essence and existence
of the person in the lowest form. Social networks also can be considered as consolidating kernel, the
original social megainstitute, which realize all spectrum of social functions. As social institute, social
networks are characterized as a strict imperious vertical, in which the user of the site cant change accepted
norms and rules.ΠΠ½ΠΎΠ³ΠΎΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°ΡΠ΅Π»ΡΡΠΊΠΈΠ΅ ΡΠ°ΠΉΡΡ, ΠΏΠΎΡΡΡΠΎΠ΅Π½Π½ΡΠ΅ ΠΏΠΎ ΡΠ΅Ρ

Unsteady Coupled Heat Transfer in the Air and Surrounding Rock Mass for Mine Excavations with Distributed Heat Sources
This paper presents an unsteady coupled heat transfer model in mine air and surrounding rock mass in the presence of distributed heat sources. The case of distributed heat sources is typical when analyzing the temperature distribution in mine excavations equipped with conveyor systems. For this case, the asymptotic value of the air temperature at the end of the mine excavation is determined not only by the heat exchange between the air and surrounding rock mass but also by the thermal power of distributed heat sources and the total airflow. This conclusion is confirmed by the experimental data presented in the paper for a longwall in a potash mine. We formulate the mathematical model and calculate the distribution of air parameters along the length of an excavation, considering heat release from the conveyor and surrounding rock mass. The results show that a distributed heat release is necessary for correctly calculating the air temperature in working areas. The numerical simulations allow us to recommend a redistribution of air between the haulage and conveyor roadways in the presence of distributed heat sources

.The relevance of the research is caused by the need to reduce the air temperature during mining operations in dead-end workings associated with the release of a large amount of heat. Development of ways to normalize the thermodynamic parameters of mine air in the faces based on the construction of predictive mathematical models of change of the thermal regime is a necessary condition for safety in the mining industry. The aim of the research is to obtain dependences for determining the rate of air temperature increase in a dead-end mine at known values of the intensity of heat release and its removal by a ventilation jet. Objects: dead-end workings and the surrounding rock mass. Methods: solution of the problem of non-stationary heat transfer of mine air and rock mass in the conjugate formulation using Laplace transformations; safety assessment on the gas factor of intensification of heat removal from the production by increasing the air supply to the bottom using recirculation. Results. The authors have analyzed the problem of heat removal, released during the operation of mining equipment in a confined space of mine workings. It is shown that heat absorption by the rock mass and its removal due to ventilation may not be enough to prevent excessive overheating of the air. A mathematical model of the conjugate heat exchange of air and rock is developed, which allows predicting the temperature increase over time depending on the length of production and the total intensity of heat release in it. It is established that heat exchange lasting several hours can be modeled in the approximation of small times, which greatly simplifies the calculated dependences. The calculation of the dynamics of the thermal regime under a set of physical parameters characteristic of mine conditions of the problem, the results of which were the basis of the approximation made and confirmed the danger of a rapid increase in air temperature with insufficient intensity of heat removal from the workings of the ventilation jet. It is proved that if additional heat removal is necessary, it is possible to use traction sources with a large flow rate and air recirculation, without fear of increasing gas content in the bottom hole

Π°.The relevance of the study is caused by the need to develop resource-saving technologies for forced ventilation of dead-end drifts related to ensuring the safety of air ducts during blasting. The solution to the problem lies in the development of technical solutions that make it possible to remove the end of the air duct from the zone of damaging effects of flying fragments of rock, moving it away from the dead-end face to a safe distance without violating the safety rules. Purpose: to develop a resource-saving method of dead-end drift ventilation, which provides the increase of the ventilation range by means of the kinetic energy of the air jet flowing from the booster fan with a mixing chamber. Objects: dead-end drifts. Methods: analytical and numerical modeling of the processes of air ejection and propagation of a constrained overlaying air jet directed to a dead end; comparative analysis of experimental data and simulation results. Results. The analysis of experimental data on the ventilation of dead-end drift by the ejection method with the lag of the end of the pipeline from the dead-end face was carried out. It is noted that the experimental dependencies obtained by various researchers for determining the range of the ventilation jet do not allow us to make an unambiguous conclusion about the permissible lagging distance due to too large spread in the values of the proportionality coefficient between it and the transverse dimension of the drifts. It was established that the reason for the scatter is the neglect of the dependence of the jet range on its initial velocity and flow rate, which is the less pronounced, the less constrained the jet is. The possibility of increasing the constraint and flow rate of the jet by ejection suction of the return air flow into the mixing chamber installed before the end of the pipeline is considered. The paper introduces the analytical model of the operation of an ejector installation with a permeable bulkhead, based on the results of which an increase in the jet flow rate due to recirculation was estimated. Despite the small value of the ejection coefficient, the numerical simulation of the process showed an unexpectedly strong increase in the ventilation range with an increase in the initial jet velocity in the real range, and the required pipeline lag result of 50 meters was achieved. It is shown that the proposed resource-saving method of forced ventilation of dead-end drifts requires a preliminary procedure for selecting and optimizing the geometric dimensions of the pipeline, mixing chamber and air flow, because in numerical simulation, both insufficient ventilation depth and loss of stability with the collapse of a single circulation vortex were observed during excessively intense air movement

ΠΌΠ°ΡΠΈΠ½.The relevance of the research is provided by the complexity of microclimate normalization in long blind drifts which are driven deeply through geothermally heated rocks. The aim of the research is the evaluation of usability of different ways for microclimate normalization in the working section of the exploration drift-2 in the mine of PJSC Β«MMC "Norilsk Nickel"Β». Objects: the exploration mine exploration drift-2 of PJSC Β«MMC "Norilsk Nickel"Β». Methods: the numerical simulation of heat and mass transfer in the atmosphere of the long exploration drift, the comparative analysis of simulation results. Results. The paper reviews ways, comparing their features, advantages, and disadvantages, for microclimate normalization in deep blind drifts. The presented mathematical model describes the heat and mass transfer in the working section of the blind drift with ventilation through the air duct. The model considers convective and radiant heat transfers. The results of the numerical simulation are given for different air-cooling methods which are applicable in the case of the deep copper-nickel mine of PJSC Β«MMC "Norilsk Nickel"Β». Drawing on this, different mining and thermal engineering operations for normalization of air temperatures in the working section regarding safety requirements are compared. It is defined that increasing the intake air flowrate could not decrease the air temperature near the face. The use of thermally insulated duct significantly decreases the air temperature in the working section but does not reduce it to the permitted value. It is shown, that the air irrigation could normalize temperatures in winter and not during the summer months. Underground air conditioning is the most universal and effective way for this purpose but highly expensive
