Ho utloisisa Merafo ea Mashala ea Coking: Tataiso e Feletseng

Sengoliloeng sena se fana ka kakaretso e felletseng ea ho pheha merafo ea mashala, ho hlahloba tšebetso ea tsona, phello ea tikoloho, le bohlokoa ba moruo. Re tla shebisisa tshebetso ya merafo, melawana ya polokeho, le bokamoso ba indasteri ena ya bohlokwa. Ithute ka mefuta e fapaneng ea ho pheha merafo ea mashala, kabo ea tsona ea libaka, le mathata ao a tobanang le ’ona.

Ho pheha merafo ea mashala ba na le boikarabelo ba ho ntša mashala a ho pheha, mofuta o itseng oa mashala a nang le lintho tse fokolang tse fokolang le lik'habone tse phahameng. Ho fapana le mefuta e meng ea mashala a loketseng ho fehla motlakase, mashala a ho pheha a bohlokoa mosebetsing oa ho etsa tšepe. E sebelisoa liboping tsa mollo ho etsa coke, mafura a thusang ho fokotsa ore ea tšepe ho tšepe. Thepa ea mashala a ho pheha, e leng bokhoni ba eona ba ho mamella mocheso o phahameng ntle le ho putlama, ke ea bohlokoa bakeng sa ts'ebetso ena. Sebaka sa merafo ena se fapana haholo, ho latela sebopeho sa jeoloji. Major ho pheha merafo ea mashala li fumaneha linaheng tse kang Australia, China, United States, le Russia, har’a tse ling.

Patlisiso le Ntlafatso

Ts'ebetso e qala ka liphuputso tsa jeoloji ho tseba bokhoni ho pheha leshala depositi. Hang ha depositi e sebetsang e fumaneha, moralo o pharaletseng le litlhahlobo tsa phello ea tikoloho lia etsoa. Mokhahlelo ona o kenyelletsa ho fumana mangolo a tumello le ho theha moralo o felletseng oa merafo, ho nahanoa ka lintlha tse kang polokeho, ts'ireletso ea tikoloho, le taolo ea lisebelisoa. Litheknoloji tse tsoetseng pele, tse kenyelletsang lipatlisiso tsa seismic le ho cheka, li sebelisoa ho etsa 'mapa o nepahetseng oa seams oa mashala.

Mekhoa ea ho Ema

Mekhoa e 'meli ea mantlha e sebelisoa bakeng sa ho pheha leshala extraction: merafo ka tlas'a lefatše le merafo holim'a metsi (open-cut mining). Ho rafa ka tlas'a lefatše ho kopanyelletsa ho etsa lithanele le lithupa tse kenang mashala a ka tlas'a lefatše. Hangata mokhoa ona o khethoa ha seams ea mashala e fumaneha botebong ba bohlokoa. Ka lehlakoreng le leng, ho rafa ka holim'a lefatše ho kenyelletsa ho tlosa likarolo tse holim'a lefatše ho pepesa moroko oa mashala, ho etsa hore e be e loketseng haholoanyane bakeng sa li-deposit tse sa tebang. Mekhoa ena ka bobeli e fana ka mathata a ikhethang le maikutlo a tikoloho.

Tshebetso le Lipalangoang

Hang ha e ntšitsoe, e tala ho pheha leshala e sebetsa ho tlosa litšila le ho ntlafatsa boleng ba eona bakeng sa ho etsa litšepe. Sena se ka kenyelletsa mekhoa ea ho hlatsoa, ​​​​ho silakanya le ho hlahloba. Joale mashala a hloekisitsoeng a isoa lifemeng tsa tšepe, hangata ka seporo kapa sekepe, ho itšetlehile ka sebaka sa morafo le setsi sa tšepe. Lipalangoang tse sebetsang hantle li bohlokoa ho boloka litšenyehelo tsa tlhahiso ea tšepe. Thepa ea lipalangoang e na le karolo ea bohlokoa molemong oa kakaretso oa ho pheha leshala ketane ea phepelo.

Tšusumetso ea Tikoloho ea Coking Coal Mining

Ho pheha leshala meepo e hlahisa mathata a bohlokoa a tikoloho. Ho rafa ka holim'a metsi, haholo-holo, ho ka lebisa tšenyong ea bolulo, khoholeho ea mobu, le tšilafalo ea metsi. Meepo e ka tlas'a lefatše e baka likotsi tsa ho putlama ha merafo le ho ntšoa ha khase ea methane. Indasteri e ntse e batla ka matla litsela tsa ho fokotsa litlamorao tsena ka litloaelo tsa moshoelella tsa merafo, ho kenyeletsoa matsapa a ho lokisa le ho nchafatsa maemo. Melao e thata le tlhokomelo ea tikoloho li bohlokoa ho fokotsa sebaka sa tikoloho ea ho pheha merafo ea mashala. Likhatelo-pele tsa theknoloji li bohlokoa ho tsoela pele ho ntlafatsa ts'ebetso ea tikoloho lekaleng lena.

Tšireletseho Meepong ea Mashala a Coking

Polokeho ke ntho e ka sehloohong ho ho pheha leshala indasteri ea merafo. Melao e thata ea polokeho le liprothokholo li teng ho sireletsa basebetsi likotsing tse kang ho phatloha, ho putlama ha merafo, le ho pepesehela thepa e kotsi. Koetliso e tsoelang pele, tlhahlobo ea kamehla, le theknoloji e tsoetseng pele ea polokeho ke karolo ea ho fokotsa likotsi tsa mosebetsing. Indasteri e lula e leka ho ntlafatsa maemo a polokeho le ho fokotsa kotsi ea likotsi ho basebetsi ba morafong.

Bokamoso ba ho Pheha Meepo ea Mashala

Bokamoso ba ho pheha leshala tlhahiso e hokahane le tlhokahalo ea lefats'e ea tšepe le phetoho ho mehloli ea matla e tsitsitseng haholoanyane. Le hoja tšepe e ntse e le thepa ea bohlokoa kahong le ntlafatsong ea meralo ea motheo, indasteri e tobane le khatello ea ho fokotsa khabone ea eona. Sena se hloka hore ho be le lipatlisiso tse tsoelang pele le nts'etsopele ea mekhoa ea tlhahiso e hloekileng le ho hlahlojoa ha lisebelisoa tse ling ho fokotsa ts'epo. ho pheha leshala tlhahisong ea tšepe. Ntlafatso ea theknoloji ea ho hapa le ho boloka khabone le eona e ka bapala karolo ea bohlokoa ho bopeng bokamoso ba indasteri ena.

Papiso ea Merafo ea Mashala a Coking e Fapaneng (Mohlala oa Boitsebiso - E Hloka Phetoho ea Lintlha tsa 'Nete)

Tlhokomeliso: Lintlha tse hlahisitsoeng tafoleng e ka holimo ke tsa merero ea litšoantšo feela 'me li lokela ho nkeloa sebaka ke lintlha tsa sebele tse tsoang mehloling e tšepahalang.

Bakeng sa tlhaiso-leseling e batsi ka lisebelisoa tse tšoarellang le tharollo ea indasteri, nahana ka ho hlahloba lisebelisoa tse fumanehang ho Inner Mongolia Xinxin Silicon Industry Co.,Ltd. Ba fana ka tharollo e ncha bakeng sa liindasteri tse fapaneng.
