Based on the developed method of measuring density of peat bound water on drying colloidal and capillary-cellular bodies, the authors of the paper made an effort to explain its relation with anomalous properties of free and bound water by the proposed engineering model.

TECHNOLOGICAL EVALUATION OF ROLLER-PRESS APPLICATION IN COMMINUTION FLOW SHEETS OF OXIDIZED FERRUGINOUS QUARTZITES
Crushability and grindability of oxidized iron ore sample were studied using standard crushers and roller-press LABWAL 250Х100 produced by Thyssen Krupp Polysius. Noted data illustrate that during grinding of products from crushing step, roller-press shows absolute value decreasing of useful energy specific cost comprises of 3,9 kWh/t with feed dimension of ball mill -5+0 mm and 3,3 kWh/t with feed dimension of ball mill -10+0 mm (80% -6 mm, open-cycle processing of roller-press). Crushed products specific surface of oxidized ferruginous ore has been determined after treatment by crusher of standard construction and roller press of laboratory scale
Key words: oxidized ferruginous quartzite, roller-press,specific surface.
OPTIMIZATION OF THE NEGATIVE IMPACT OF MINING PRODUCTION WITH THE HELP OF INTEGRAL CRITERIA OF ASSESSMENT OF ENVIRONMENTAL HAZARD
In the current context of limited material resources is an objective and sufficiently rapid assessment environmental hazard of a technological or organizational solutions, the enterprise as a whole, is an absolute must. This article describes a new approach to the evaluation of environmental hazards of mining, which allows to optimize its negative impact on the environment.
Key words: ecological hazard, ecological safety, negative impact on the environment, assessment of environmental hazard, integral criterion.
THE ANALYSIS BASE RESEARCH AND SCIENTIFICALLY-METHODICAL DECISIONS APPLICABLE IN COMPLICATED CONDITION OF THE PRODUCTION. SYSTEM DEVELOPMENT TO CATEGORIZATIONS OF THE METHODS AND TECHNOLOGY
In article is organized analysis base research and scientifically-methodical decisions applicable in complicated condition of the production. It Is Shown that physicochemical methods present itself efficient instrument of increasing oil recovery when hard extraction oil stocks production, as well as at construction of the bore holes in complex is blazed-geological condition and at exploitation of the bore holes in complicated condition. Introduces that potential physicochemical methods far from exhausted, but opposite, has a good outlook for expansion and qualitative renovation. The main trend of the development physicochemical methods consists in more deep study of the application domain – a composition and characteristic to oils, features argillaceous deposits and etc., and in creation corresponding to methods and technology with use physicochemical approach in combination with the other methods.
Key words: complicated conditions of the production, methods of the increase oil recovery, hard extraction oil stocks, oil recovery factor, categorization physicochemical methods, methods of the address influence, complex and scientifically-methodical decisions.
THE STATE COMMERCIAL ENTERPRISE AS THE MAIN SUBJECT OF THE ECONOMIC RELATIONS IN THE MINERAL AND RAW COMPLEX OF RUSSIA
In article is investigated the economic essence of the federal state unitary enterprises as the businesses, and also shown their specifics conditioned their functions. At the same time is given the characteristic of the government entrepreneurship and achieved factors are influencing public industries of the mineral and raw complex.
Key words: federal state unitary enterprise, firm, mineral and raw complex, government entrepreneurship.
MAINTENANCE FOR BOOK "INTRODUCTION TO CURRENTS & ELECTRONIC MODELS"
All modern microchips appeared to be the part of standard nomenclature as being Intel & Maxim compatible, — in amount equipped with band-striped input/output, so they all include complex structure, in particular their declared topologies, & mathematical models also enough complex. In odder to understand basic terms & formulas & formula prefaces (known as object of intellectual property) it is needed to прибегнуть to recourse to basic calculations & visual oscillograms, which confirm observability for electronic schemes & physical processes, that dedicates these book as previous one before "Currents". More than that, it is necessary to analyze necessity of job on exact model for electronic scheme & opportunity for developing expert system for modeling based on oscillogram database.
MAINTENANCE FOR BOOK "SCHEMES AFTERWARDS CURRENTS & RADIO"
Microchip & microcontrollers appeared to be complex devices, in lots of cases it is needed developing of inner & outer conjugating devices & schemes. Such devices in the point of fact are declared objects of industrial & intellectual property, known as declared topological decisions. "Schemes" as volume of "Electronics" multivolume is a well known way in studding electronics & schemes. However, "Schemes after "Currents" allows at level upper to look at schemes & complex conjugating devices with making models for transfer function & signals with to leading edges. There are different ways to the edge mathematical appearance. Book "Currents" exactly answers that topological decision obtains as a result of special transformations optimization, & special compositional methods. On common methods to modeling different schemes in electronics, radio & telephony there is an opportunity not to make difference between scheme functional purpose, & it is not needed to use voltage & currents transfer functions, it is enough to use the only transfer function, as it's enough mathematically evidently, & technically quite enough, so can be proved. After "Currents" it is not needed to observer all the kinds of schemes for exact electronic modeling.
