M'dera la Leningrad muli madambo ambiri, omwe amakhudza mitundu yazinthu zachilengedwe. Kafukufuku wa akatswiri ofukula zinthu zakale asonyeza kuti kuphulika kwa mapiri m'mbuyomu kunapangitsa kuti pakhale mchere wambiri womwe ukupangika kapena chiyembekezo chofuna migodi.
Dera la Leningrad ndi dera lolemera, pali miyala yamiyala, bauxite, shale, phosphorites, mchenga, dongo, peat. Kufufuza mozama za zachilengedwe kumavumbula nkhokwe zonse zatsopano zachilengedwe:
- mpweya;
- kumaliza miyala;
- phula;
- magnetite miyala.
Kupezeka kwapang'ono kwa bauxites kunapangitsa kuti athe kuwachotsa poyera. Migodi yotseguka yazida zikuwonekera pamtengo wawo. Mosiyana ndi bauxite, mafuta shale ndi phosphorites amafuna migodi.
Mitundu yambiri yamchere mderali
M'dera la Leningrad muli nkhokwe zazikulu za granite, dongo lowonongeka, njerwa zamiyala, mchenga. Izi ndizofunikira kwambiri pakati pa makampani akumanga. Granite imayikidwa pa Karelian Isthmus, yapeza ntchito pomaliza ntchito yomanga. Pafupi ndi tawuni ya Pikalevo akupangidwa miyala yamiyala.
Madambo amapereka mwayi wopanga peat wamafuta, omwe amagwiritsidwa ntchito muulimi ndi mafakitale. Ma peat akulu kwambiri amapezeka kumwera ndi kum'mawa kwa dera. Kukhalapo kwa nkhalango kumapangitsa dera la Leningrad kukhala lopezera mitengo yambiri. Kumpoto chakumadzulo kwa Russia, derali ndi limodzi mwamalo otsogola.
Pali magawo 80 mderali omwe akutukuka. Boma lili ndimadontho 173 papepala, pomwe 46% yokha ndi yomwe ikupangidwa.
Pali akasupe akulu amadzi amchere omwe amapezeka:
- sodium mankhwala enaake Sestroretsk;
- madzi a sulfuric ku Sablino;
- Polyustrovskie carbonate ku St. Petersburg;
- Akasupe amchere amchere pafupi ndi Luga (malo osungira madzi obisika).
Pazogulitsa zamagalasi, kuchotsa mchenga ndikofunikira kwambiri, komwe kumagwiritsidwa ntchito kusungunula ndikupanga zinthu zamagalasi. Mundawu udagwiridwa kuyambira 1860 mpaka 1930. Krustalo yachifumu yotchuka imapangidwa ndi mchenga uwu. Kuchokera kwa dothi labuluu la Cambrian kumpoto kwa derali. Ndalama imodzi yatha, ndipo yachiwiri ikukonzedwa mwakhama ndi migodi yotseguka.
Mukamapanga mchere, mitundu yotsatirayi imagwiritsidwa ntchito: geotechnical; zomangamanga ndi geodetic; zomangamanga ndi hydrometeorological; zomangamanga.
Maofesi osakhazikika
Pali magawo a miyala yagolide m'derali, koma ndi ochepa ndipo sanapangidwebe. Izi zimakopa anthu ambiri osaka chuma. Kuphatikiza apo, pali madipoziti a diamondi, koma chitukuko chawo chimangokhala mu ntchitoyi.
Dera lino lili ndi mchere wambiri womwe sukukonzedwa, womwe ndi:
- utoto wamchere;
- manganese;
- maginito miyala;
- mafuta.
Kukula kwawo kwapangidwa posachedwa, ndipo izi zipatsa mwayi wowonjezera ntchito ndikuwonjezera bajeti.
