Development of the concept of an innovative laboratory installation for the study of dust-forming surfaces

Article preview

Currently, the determination of the emission rate of suspended solids from a unit of the surface area of a man-made mass at various parameters of the wind flow is not sufficiently described. The analysis of the world experience of researchers shows that existing laboratory installations have various design features that do not allow to correctly determine the mass of the dust being flapped and wind-blown. Based on the analysis results, the concept of an innovative laboratory installation for the study of dust-forming surfaces has been developed. It takes into account the influence of wind shadows, the deturbulization of an artificially created air flow, the possibility of regulating not only the flow velocity mode, but also the creation of a vacuum or disturbance in the area of sample placement, as well as the formation of a certain angle of wind flow attack relative to the surface. The concept provides for the possibility of determining the volume of dust emissions by the values of the lost dust masses in the sample and by the values of dust concentrations in the outgoing stream. The calculation of the main basic elements of the installation using the ANSYS FLUENT software package was carried out. The model and configuration of the wind tunnel have been developed and calculated, the main geometric parameters and functional elements for the possibility of use in scientific work have been determined. For practical use of the empirical roughness value of the underlying surface, its values are recommended in a wide range – from zero for the water surface to 0.44 for large cities with tall buildings and skyscrapers.

METROLOGICAL SUPPORT OF MONITORING SYSTEMS BASED ON UNMANNED AERIAL VEHICLES

Article preview

The article discusses the fields and methods of application of unmanned aerial vehicles (UAV). Current legislation in Russia and in the world, significantly limit the use of UAV in monitoring. For the first time, we present a solution to the problem of a monitoring measurement system included in the state register of measuring instruments using the example of the basic UAV model. We conducted an analysis of promising approaches to the creation of UAV metrological and methodological support, as well as ways to adapt their target load to meet the challenges of operational monitoring of air pollution.

Using of steam condensing way of dust-depressing in different manufacturing operations during mining

Article preview

In places of possible allocation of a dust, near sources of its formation or at allocation places ways of dust-depressing now are applied. Principal views of dust-depressing are: a water irrigation (including dispersing, the ionized water), a foamy irrigation (aerofoams, air-mechanical foams), an irrigation steam (fog). In article condensation of steams of water on a surface of hygroscopic particles is considered stream-condensation way of dust-depressing, based on action.

Dust control at coal enterprises of the North

Article preview

In Saint Petersburg State Mining Institute series of measures aimed at protection of environment from harmful impact of technological processes during open-cast mining and underground operation of coal, which is the most popular power resource for today are carried out. In future coal will be one of the main resource, as its supply may satisfy the needs of all branches of industry for a long period of time. The problem of stable maintenance with a heat and electric energy of the north remote territories, settlements, objects of ability to live of the person is stubborn in a modern level of development of a fuel and energy complex of Russia. Application of new technologies on use of local renewed energy sources in small energetic will allow to approach essentially manufacture of energy to the consumer and to involve in manufacture of heat and an electricity alternative kinds of fuel.

Use of long-lived solidifying foams for protection of working spaces from dust and gas explosions

Article preview

Mining is closely connected with human impact on the environment in order to provide it with primary resources. In the SPMI laboratory under the guidance of Prof. Yu.V. Shuvalov, a number of measures have been taken to protect the environment from the harmful effects of technological processes in open pit and underground coal mining, which is currently the most demanded energy resource. In the future, coal will be one of the main resources, as its supply can meet the needs of all industries for a long period of time. The research was supported by the Government of St. Petersburg, CRDF USA, the Ministry of Education and Science of the Russian Federation and REC-015 at SPMI, Russia.

New technologies to ensure safety in mining in Russia

Article preview

Mineral extraction is closely connected with the processes of human impact on the environment in order to provide raw materials and their partial loss. With the total extraction of mineral resources exceeding 6.5bn tons, the total losses in the subsoil amount to 2.5bn tons: about 50bn tons of harmful substances are emitted into the atmosphere, more than 2bn m3 of polluted waste water is discharged into water bodies and more than 8bn tons of solid waste is stored on the surface of the earth. The scientific school of SPGGI is developing a set of measures to protect the environment from the harmful effects of technological processes in open-pit and underground coal mining, which today is a demanded natural energy resource, and in the future will become one of the main ones, as its supply can satisfy the needs of all industries for several hundred years.

Rational ways of protection of recultivated soils

Article preview

An important problem of anthropogenic massifs is the slowdown in the natural formation of vegetation cover on dumps and tailings dumps of mining enterprises, which is explained by the impoverishment of rocks with nutrients. In this regard, of particular importance are the studies aimed at developing economically feasible ways to reduce dust emissions into the atmosphere and restore the biological productivity of disturbed areas, excluding the performance of labor-intensive operations to apply a traditional soil layer during reclamation. Based on the study of properties of various biologically active substances, the use of a new environmentally friendly bioactive foam is proposed, which fulfills the main tasks of biological reclamation: return of disturbed lands to the agricultural fund and fixation of dusty surfaces (soils, dumps, tailings).
