Technology and economics of near-surface geothermal resources exploitation

Article preview

The paper presents economic justification for applicability of near-surface geothermal installations in Luga region, based on results of techno-economic calculations as well as integrated technical and economic comparison of different prediction scenarios of heat supply, both conventional and using geothermal heat pumps (GHP). Construction costs of a near-surface geothermal system can exceed the costs of central heating by 50-100 %. However, operation and maintenance (O&M) costs of heat production for geothermal systems are 50-70 % lower than for conventional sources of heating. Currently this technology is very important, it is applied in various countries (USA, Germany, Japan, China etc.), and depending on the region both near-surface and deep boreholes are being used. World practice of near-surface geothermal systems application is reviewed in the paper.

Thermal, power and economic parameters of innovative technology of development of nearsurface geothermal deposits

Article preview

Deficiency of organic fuel and necessity of protection of environment cause growth of rates of development practically inexhaustible, everywhere widespread and ecologically pure geothermal resources. For needs of a heat supply especially actively developing innovative technology of development of near-surface geothermal resources has great value. Operative mining of the production schedules containing optimum parametres and indicators PSGT is necessary for designing and building of near-surface systems of a geothermal heat supply (PSGT). The imitating economic-mathematical model is developed, the algorithm and the program of their optimisation are created. Computer calculations for a wide range of natural, power and economic conditions are carried out. Key parametres and indicators PSGT are defined. Their optimum values for a heat supply of local consumers (apartment houses) in the conditions of the Yaroslavl area are recommended.

Heatmasstransfer to nearsurface geothermal systems

Article preview

The paper is concerned with mathematical modeling of heat and mass transfer in subsurface geothermal systems. Heat exchanger is driven as a vertical channel in an impermeable rock massive. The temperature of rock is driven in accord with a usual thermal conductance equation on a cylinder coordinates basis. The boundary conditions between the rock and heat exchanger are given by the equality of a thermal flow.

Development of geothermal resources – higher efficiency in utilization of the earth’s interior

Article preview

Preservation of Russia as the great state, its further development and prosperity, appreciably depends on possibilities to provide its own power needs, and also fuel and electric power export. On this historical period, power resources are the basic trading source of replenishment of the state budget. However, oil resources, at preservation of volumes of its export, are quickly exhausted; natural gas is not boundless too. Coal stocks have essentially decreased with disintegration of the USSR, and the remained demand considerable investments, increase of current expenses and are characterised by decrease in quality of coals. Additional expenses on ecological protection of environment will increase. Search of alternative to the organic fuel, burnt in heating plants, is conducted more than ten years. Use of low-temperature sources of thermal energy of resources is one of general directions in the decision of this problem in the XXI-st century. It proves to be true: certain advantages of geothermal resources, a readiness of scientific bases of their development, world industrial experience and specificity of systems of a heat supply in the country.

Управление качеством руды – основа горно-технологического менеджмента

Article preview

В условиях современных рыночных отношений базой менеджмента на горных работах становится управление качеством руды. Можно выделить следующие его этапы: определение рыночных цен на добытую руду; формирование границ рудных тел при переборе рациональных кондиций; определение оптимальных затрат и цен на добытую руду при рассматриваемых кондициях; формирование планов горных работ по принципу соответствия рыночных и расчетных цен на добытую руду; оперативное управление горными работами (подбор оптимальной «шихты», формирование рудопотоков, организация транспорта, подъема, складирования, ведение очистных, подготовительных, горно-капитальных и других работ).

Article preview

On the basis of economic-mathematical models (EMM) a comparative assessment of the influence of the main natural factors on the design, technological, exergy and economic parameters and performance of geothermal heating systems (GHS) was carried out. It allowed creating and recommending a new express methodology of their calculation on the territory of Russia. The created methods of EMM and express analysis can provide the first stages of GHS design and, in particular, justification of investments and development of business plans. Examples are given for promising regions of Russia.

Проблемы эффективной разработки сложных жильных форм

Article preview

Правильный выбор системы подземной разработки и ее основных конструктивных элементов особенно важен для предприятий, разраба­тывающих сложные жильные формы. На таких предприятиях производ­ственный процесс обычно завершается получением концентратов, поэтому эффективная система разработки должна обеспечить минимальную стои­мость конечной продукции. В связи с этим выбор системы разработки включает следующие этапы: отбор эффективных систем разработки по горнотехническим и технико-экономическим факторам; сравнительную экономическую оценку отобранных систем разработки; промышленные исследования отобранных систем разработки и уточнение их основных конструктивных элементов; технико-экономический анализ систем и ре­комендация наиболее эффективных вариантов ...

Режим выпуска руды из разветвленных по восстанию магазинов

Article preview

Одно из полиметаллических месторождений Союза, где мощность жил колеблется от нескольких сантиметров до 2—3 м и углы падения от 25 до 90°, представлено разнообразными жильными формами, среди которых широко распространены ветвящиеся рудные тела. Особенно сложна разработка жил, ветвящихся по восстанию, так как приемлемость производительной на тонких жилах системы с магазинированием руды определяется возможностью частичного выпуска руды из разветвленных магазинов на общий этажный штрек. От этого зависят выбор варианта системы разработки,* объем подготовительно-нарезных работ, производи­тельность труда и себестоимость руды. Возможность частичного выпуска при одновременной отбойке во всех разветвлениях жилы (основной жилы и апофиз) определяется скоростью истечения руды из магазинов по жиле и апофизам ...
