EFFECT OF FLOW OF MUD ON DRILLING PROCESS. THE CASE OF THE NEWTONIAN FLUID

abstract 0741110034 issue 74 pp. 384 – 395 30.12.2011 ru 1958
Physical 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

MODEL OF IDENTIFICATION OF A PROCESS OF DUST CONTENT OF THE AIR OF WORKING ZONE IN FOUNDRY MANUFACTURE

abstract 0741110014 issue 74 pp. 164 – 175 30.12.2011 ru 1639
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received

AUTOMATIC CONTROL SYSTEM OF CHARACTERISTICS OF DEVICES OF MOVING ON THE AIR PILLOW

abstract 0741110012 issue 74 pp. 144 – 153 30.12.2011 ru 1516
Methods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of
