Valley р. Angren in the Tashkent area is most industrially advanced
region of Uzbekistan and all Central Asia. Here the
mining enterprises, including Ангренский угольно-каолиновый a complex of joint-stock company " coal " successfully
This unique enterprise in republic obtaining coal. Into structure of joint-stock company " coal "
enter a number of the coal-mining enterprises.
Uzbekistan has the reconnoitered stocks of coal in volume 1,9 billion т.
The coal mining in republic is conducted on three deposits: Ангренское (brown coal),
Шаргуньское and Байсунское (coal).
The coal mining on Ангренском a deposit brown углей with the general(common) stocks 1850
million т is conducted by three enterprises with essentially various technology of extraction: coal
cut(section) "Ангренский" the mine(shaft)
№ 9 - a underground way, - station " Подземгаз " a method of
underground gasification conducts improvement of stocks by an open way. The volume of an annual coal
mining on a deposit makes about 5
Вскрышные breeds Ангренского of a deposit of coal contain каолины, limestones,
quartz sand and loams which are extracted in passing and are used now
very much is limited. Каолиновая thickness of a deposit is submitted by two types
of breeds: initial каолины, deposited below coal layer, and secondary переотложенные
каолины, deposited above a coal layer. On balance 1,4 billion т каолинов,
authorized is as raw material for manufacture of alumina, cement and a brick,
including 33 million т initial каолинов - as raw material for manufacture
огнеупоров, electroisolators and thin ceramics, porcelain, and also 3,6 million т
secondary каолинов as raw material for a ceramic industry.
It is most perspective and expansion of
use secondary grey and multicoloured каолинов is economically expedient.
Secondary grey and multicoloured каолины are extracted in passing with coal in quantity(amount)
5 million tons per one year, that under condition of their enrichment completely can provide
needs(requirements) not only republics but also to export the given kind of raw material. Transition
of the basic consumers of republic on каолины Ангренского deposits, and
also construction on their base of new factories, including on manufacture огнеупоров,
sanitary articles from faience, ceramic плитки completely will allow to
refuse import of the given raw material from other countries.
Construction of a factory on crushing and enrichment каолина will
allow to expand sphere of his(its) application considerably.
Except for Ангренского deposits, joint-stock company " coal " are developed Байсунское
and Шаргуньское deposits in the Surkhan-Darya area.
Шаргуньское and Байсунское coal deposits with the general(common) stocks 44
million т are fulfilled by a underground way for maintenance with coal of southern regions
of Uzbekistan, and also Tadjikistan and Туркмении.
On the basis of mine(shaft) " Шаргуньская " the factory by
a designed capacity 200 thousand т briquettes is constructed брикетная. As binding by manufacture of
briquettes the technology traditional for similar conditions with application нефтебитума is used.
Байсунский coal, in view of the high qualities, can be
used as valuable chemical raw material (коксобрикеты, адсорбенты, liquid fuel etc.).
Estimation of an existing condition of the enterprises of branch have allowed to reveal priority
directions of development and reorientation of coal branch by attraction of
foreign investments. Development of these directions should improve an economic condition
of the enterprises which are included in association and to raise(increase) an export potential of branch.
In particular, this introduction of high technologies of manufacture of works on mountain
extraction and replacement on new the out-of-date equipment.
The need(requirement) of republic for a corner will be saved in volume 4,0-4,5 thousand т per one year.
opportunities will increase by 2000 up to 320 thousand т per one year. With 1999 is
planned to begin manufacture enriched initial каолина in quantity(amount) 120 thousand т
per one year and to finish his(its) manufacture up to 200 thousand т per one year by 2000, directing
all made product on export.
The basic gain of a coal mining the nearest years also is in the long term planned to
be carried out due to development of an open way of extraction on cut(section) "Ангренский".
