ANALYSIS OF PROCESS OF DESTRUCTION OF ROCKS WITH A CHISEL АT DRILLING OF BORE HOLES
DescriptionТhe physical processes, arising on a face at interaction of a chisel with rocks are considered. The mathemati-cal description of model of mechanical speed of drill-ing in a function from speed of rotation, twisting mo-ment, diameter of a chisel and properties of destroyed rocks is executed

EFFECT OF FLOW OF MUD ON DRILLING PROCESS. THE CASE OF THE NEWTONIAN FLUID
DescriptionPhysical processes, arising up at removing of rock from the backwall of mining hole, are considered. The curve of sedimentation, allowing to determine the rate of climb of transporting of rock at cleaning of back-wall with newtonian liquids – air and water, is shown. The formula is shown out for the calculation of ex-pense of borax solution, necessary for the high-quality cleaning of backwall of mining hole at washing water or air

01.00.00 Physical-mathematical sciences
DescriptionArticle is devoted to the numerical analysis of regional problems for system of the equations of Nernst-Plank-Puasson (NPP), to application of these regional problems to modeling and studying of mass transfer in the channel desalting of electro dialysis device. Various mathematical models of the transfer of ions in potential static mode in the form of system of the quasilinear equations with private derivatives are offered. The basic rules of occurrence and development of a spatial charge in the channel desalting of electro dialysis device are revealed

DEVELOPMENT OF MATHEMATICAL MODEL OF PROCESS OF HEATING OF AIR FOR DRYING GRAIN
01.00.00 Physical-mathematical sciences
DescriptionIn the article, the analytical way of working out of mathematical model of process of heating of air for grain drying is shown. It is considered, that the temperature of a wall influences on dynamics of process of heating. Dynamic characteristics of the top internal device are considered. With use of package Mathcad schedules of transitive functions on operating and revolting influence are received. Results of modeling are presented

Description
The article is devoted to the decision of an actual problem of consideration of an estimation of assimilation territory potential, as one of indicators of an ecological estimation of city territories. In this article, the estimation approximating calculations of an economic estimation of assimilation of potential atmosphere as element of national wealth on the basis of available information about assimilation abilities of air pool, expenses for its clearing and damage from pollution is resulted

Description
This article has examined the signs by which you can group all the technical means to collect information about the interaction of termobarometrical underground oil and gas facilities with the environment. The analysis showed, that despite the long history and variety of instruments for measuring pressure and temperature, there is a small set of tools for measuring deep inside the well bore, we know only a few works on the casing tube inserted into special tubes with tensometers placed on them to measure the mechanical deformations, axial forces and temperature, and only a few details about the individual experimental studies of total pressure at the borehole wall and the temperature. Unknown devices to measure except in the casing annulus pressure of the total pressure generated by a separate solid and liquid (gas) phases of the environment

OPTIMUM SPEED OF DIAGRAMS FOR CHANGES OF TEMPERATURE OF A PRODUCT IN THE DEVICE OF AIR COOLING
DescriptionThree diagrams are developed for the changes of temperature of a product in air cooling devices with restrictions of speed of the systems’ performing parts of electric drive and it’s various derivatives at dispersal and braking. Parameters of optimum diagrams of speed for the big changes of temperature of a product in devices of air cooling are defined
