KP "Kirovgeologiya" is conducted by own forces production of a block stone: GABRO, granite and labradorite
The Southern site of the Bystriyevsky field of a gabbro is located at distance of 0,6 km to the North from the village Kamenyi Brid in Korostyshevsky district of the Zhytomyr region.
The main mineral on the field is invariable aeration of a gabbro of a Korostensky complex of early Proterozoic age. A gabbro from dark green-gray to light - green-gray color medium-grained, fine-grained, dense. Power of not changed gabbro within stock counting to the horizon +152,5 m makes 31,0 - 34,8 m, on average - 33,7 m.
On complexity of a geological structure Southern site of the Bystriyevsky field according to Classification of stocks and resources of minerals of the state fund of a subsoil of Ukraine is reasonably referred to group of objects idle time of a geological structure (1 group) with the sustained quantitative and qualitative parameters of mineral.
The Bystriyevsky field is reconnoitered in 1989-1990 for the purpose of creation of a source of raw materials for the enterprise. By results of the carried-out works stocks of a gabbro suitable for production of blocks in number of 2464 thousand m3 on category A are approved.
In 1998 expedition No. 49 of the Kirov DGP performed separation of the Bystriyevsky field of a gabbro on Southern (the operating pit) and Northern (the area which is not damaged by mining operations) sites. By results of distribution of GKS to a state for 01.01.1998 gabbro stocks as block raw materials in number of 2430 thousand m3 on category A, including on the Northern site - 881 thousand m3, on the Southern site - 1540 thousand m3 are approved.
In 2004 the state Kirovgeologiya enterprise that is a legal successor of the Kirov DGP got special permission to use of natural resources of Public service of geology and a subsoil of Ukraine of 28.12.2004 No. 3581, provided for the purpose of production of a gabbro as a facing stone on the Southern site of the Bystriyevsky field on the area of 5,2 hectares by validity period for 14 years.
In the state stock balance of minerals as of 01.01.2015. On the Southern site of the Bystriyevsky field gabbro stocks in number of 1347,68 thousand m3 on category A are considered.
The field Mikovske-1 of labradorite is in Korostyshevsky district of the Zhytomyr region.
The geological structure of the area and field differs in simplicity. Crystal breeds are rich with a gabbro-anortosites of a Korostensky complex of the middle Proterozoic age and bark of their aeration, become covered by sandy-argillaceous formations of quarternary time.
The field Mikovske-1 it is made by labradorite coarse-grained, darkly gray.
The field Mikovske-1 of labradorit concerns to 1 group idle time of a geological structure according to Classification of stocks and resources of minerals of the state fund of a subsoil of Ukraine.
As of October 1, 1997 the balance sheet stocks of undisturbed labradorit of aeration of the field Mikovskogo-1 of nation-wide value suitable for production of blocks according to GOST 9479-84 on category A, in quantity - 1112,6 thousand m3.
As of October 1, 1997 balance sheet stocks of the field Mikovskogo-1 labradorit broken the aerations suitable for production of construction crushed stone according to GOST 8267-82 on category A in number of 37,2 thousand m3.
As of October 1, 1997 reserves of the accompanying loams and kaolins of the field Mikovskogo-1, are previously studied as it is possible raw materials for production clay a construction brick (OST 21-78-88 "Raw materials clay (rocks) for production of a ceramic brick and stones") in contours and figures on recalculation in compliance in item 3.2 of this protocol on category C2 in quantity (one thousand m3) loams - 52,2 kaolins-105,6.
The Mezhirichsky field of granites is located at distance of 0,8 km to the East from the village of Mezhirichka in Korostensky district of the Zhytomyr region. The closest railway station of Ignatpole is located at distance about 8 km to the southwest from the field.
Operation of the field is carried out since 1996.
According to operational works of 1999-2002. An exit of blocks from the mountain mass of granites of Mezhirichsky field changed ranging from 17,3 to 27,2% that was less than the size accepted by GKS (the GKZ protocol of 14.12.1995 No. 357) - 35%. In 2003 GKS for five years were approved operational standards and reserves of granites for (categories B, the number of 50 thousand m3) which had to be developed in 2003-2008 are overpriced. In a southwest part of the field on the site within the horizons of 143 m, 137 we 131 m (the GKZ protocol of 03.09.2003 No. 768). For these stocks an exit of blocks from mountain weight of 23,5% was accepted (minimum industrial exit of blocks - 15%).
In 2008 KP "Kirovgeologiya" executed revaluation of reserves of granites of Mezhirichsky field taking into account stocks of Southwest area and carried out field geological economic evaluation. By results of the carried-out works of GKS reserves of the granites of the main mineral (which are not changed by aeration of granites) in number of 1335 thousand m3, including on categories (thousands m3) are approved: B - 1002 m3, C1 - 333 m3 and stocks jointly the lying minerals (broken aerations of granites) in number of 42 thousand m3.
In 2014 KP Kirovgeologiya got special permission to use of natural resources of Public service of geology and a subsoil of Ukraine of 27.02.2014 No. 5912, Mezhirichsky field provided for the purpose of extraction of granites of the field validity period for 20 years.
In 2015 KP Kirovgeologiya executed repeated geological economic evaluation of Mezhirichsky field of granites. On 01.01.2015 were accounted the reserve of the granites of Mezhirichsky field suitable for production of blocks in number of 1323,3 thousand m3, including on categories (thousands m3): B - 990,3, C1 - 333,0.
Security of the enterprise with reserves of granite of Mezhirichsky field makes more than 44 years at the annual power of a pit on production of mountain weight of 30 thousand m3.
Breeds of a Korostensky intrusive complex of Proterozoic age, their bark of aeration and adjournment of quarternary age take part in a geological structure of the field.
The main mineral on the field is provided not changed aerations of granites of a Korostensky complex of middle Proterozoic age. Power of the main mineral to the stock counting horizon (+113,0 m) changes ranging from 2,6 m to 32,5 m, averages 15,1 m. The jointing of granites is very uneven as in the plan, and down.
Jointly the lying minerals are the granites that affected by aeration. Which power changes ranging from 0,8 m to 6,4 m.
On complexity of a geological structure the Mezhirichsky field of granites is carried to group of fields difficult a geological structure (the 2nd group) according to сlassification of stocks and resources of minerals of the state fund of subsoil.
