I. Kukosha kwePillar Recovery uyeGob Area Processing
Mumigodhi yepasi pevhu, kudzoreredza mbiru uye kugadzirisa nzvimbo yegob kwakakosha uye kwakanyatsopindirana maitiro ayo anosiya kukanganisa kwakadzama mukusimukira kwezvimbambaira. Mbiru zvinhu zvakakosha zvimiro zvekutsigira nzvimbo dzepfungwa. Kudzoreredza kwakanaka kwembiru idzi kunopesvedzera zvakananga kudzoreredzwa kwezviwanikwa zvepasi pevhu uye kunotaridza kubatsirwa kwehupfumi hwemugodhi. Huwandu hukuru hwesimbi huchasiiwa kana hukatadza kudzoserwa nekufamba kwenguva, zvichizokonzera kurashikirwa kukuru uye kurasikirwa kukuru mukuwanikwa kwemari mumigodhi.
Panguva imwecheteyo, isina kukodzera gob nzvimbo yekugadzirisa inogona kutungamirira kune dzakatevedzana dzekuchengetedza nyaya. Ground pressure inoungana nekuwedzera kwenzvimbo dzegob, kuwedzera njodzi dzembiru deformation uye kutadza pasi pekunetseka kwakanyanya. Izvi zvinogona kukonzeresa kukoromoka kukuru kwedenga, kufamba kwematombo, kudzika kwepasi, kuputika, uye kudonha, zvichikonzera njodzi kuvashandi vepasi pevhu nemichina.
Kusakwana kwembiru kudzoreredza uye kugadzirisa kwenzvimbo kunogona kutungamira kumatambudziko ezvakatipoteredza senge kuvhiringwa kwemvura yepasi, kukuvadzwa kwezvinomera pamusoro, uye kusaenzana kwenzvimbo. Naizvozvo, sainzi uye inobudirira mbiru kudzoreredza uye pfungwa-kunze nharaunda kugadzirisa kwakakosha pakugadzirwa kwakachengeteka, kushandisa zviwanikwa zviwanikwa, uye kuchengetedza kwezvakatipoteredza. Aya maitiro anoda kutariswa kwese kwehukama hwavo hwakarukwa muzvirongwa zvemigodhi.
II. Pillar Recovery
(1) Nzira Dzakajairika
Nzira dzekudzoreredza mbiru dzinosanganisira kumira kwakavhurika, kudzosera kumashure, uye kubako, imwe neimwe inokodzera mamiriro chaiwo anoenderana.
Vhura Kumira isarudzo yakanakira orebodies ine dombo rakagadzikana uye nzvimbo dzakakosha dzekuratidzira. Inoratidzira maitiro akareruka emigodhi uye mutengo wakaderera asi inosiya akawanda akasara mbiru. Kunonoka kana kusagadzirisa kupora kunogona kukonzera kushushikana kwakanyanya, zvichiunza njodzi dzinogona kuitika kuti uwedzere kuongorora.
Backfill yakakodzera kune yakakwira-value ores kana migodhi ine yakasimba yepasi subsidence zvinodiwa. Zvinosanganisira kushandisa zvinhu zvekuzadza kudzikamisa dombo rakatenderedza, kuvandudza ore kudzoreredza mitengo, uye kuderedza deformation yepasi. Zviridzwa zvepamberi, sengeonline slurry density metres, help s yekutarisa simba rekuzadza zvinhu kuburikidza chaiyo-nguva density kuyerwa.Lonnmeterinopa zvishandiso zvakangwara zvezvigadziriso zvemigodhi.Taura nesukune zvimwe pa online slurry density metres. Nekudaro, kudzosera kumashure kunodhura zvakanyanya uye kuoma.
Caving inoiswa kunzvimbo dzakatenderedza mapako ematombo zvakajairika kana gob nzvimbo nyaya dzinogona kubatwa kuburikidza nekumanikidzirwa kubako. Iyo inodzivirira kushushikana mupfungwa asi inogona kuwedzera ore dilution uye inokanganisa matani ari padyo.
(2) Nyaya Yokudzidza
Tora kamuri-uye-mbiru nzira inoshanda semuenzaniso kuratidza maitiro ekudzoreredza zvakadzama. Mugodhi wacho waichera zvakadzika, zvakaita sefani muzvikamu zvembiru, kuchera mbiru dzakachinjika, uye kucheresa mbiru dzeuriri pakati nepakati. Kuputika kwakatevedzana kwakarongwa zvine hungwaru kubata ore kudonha kwegwara uye chiyero. Ventilation systems dzakaita kuti mweya mutsva upinde mumigwagwa ye scraper kuburikidza nemigwagwa yepasi; mhepo yakasvibiswa inobudiswa kuburikidza nepamusoro pemhepo zvakanaka kuti ive nechokwadi chehutano hwemhepo. Ipapo matombo akachekwa anopepereswa kunze nepakati uye anokweverwa kure nemota yemugodhi wepasi zvine hunyanzvi.
(3) Pfungwa Dzakakosha Pakudzoreredza
Izvo zvakakosha kuti usarudze nzira dzekudzikinura zvichibva pane chaiwo maitiro embiru mu flexible panguva yembiru kupora. Kuve nechokwadi chekuti nzira yakasarudzwa inogonesa zvose zvinobudirira kupora ores uye kuchengetedzwa kwekuchengetedza mushure mekuyera kwese pamusoro pezvinhu zvose zvakadai sehukuru, chimiro, kugadzikana kwedombo re ore, uye kugoverwa kwenzvimbo ye orebodies yakapoteredza, nezvimwewo.
Kuchengetedza kugadzikana kwembiru kwakakosha panguva yekudzorera. Munguva yekumisa kudzoreredza nhanho, migodhi paramita inofanirwa kudzorwa zvakanyanya kudzivirira kukuvadza kwakanyanya kune mbiru. Panguva yekudzoreredza mashandiro, kushushikana kwembiru uye deformation mamiriro anofanirwa kutariswa munguva chaiyo. Kana pane zvisizvo zvakaonekwa, nzira yekudzorera inofanira kugadziriswa nokukurumidza. Izvi zvinogona kuwanikwa nekuisa midziyo yakadai senge stress sensors uye displacement monitors kuti ive nechokwadi chekutonga kwembiru.
Preliminary mining design ndiyo nheyo yekubudirira kupora kwembiru. Kurongeka kunonzwisisika munzira yemumugwagwa uye mukamuri, pamwe nemasisitimu akabatanidzwa ekufemesa mhepo, zvekufambisa uye dhiraivha zvese zvinopa mabhenefiti kune kunotevera kuchera, kuputika, uye kuchera ore mashandiro. Semuenzaniso, iyo chaiyo dhizaini ye gradient uye kureba kwemucking drifts inovimbisa kufambiswa kwakanaka kwesimbi.
Kuputika uye kubviswa kwesimbi kunofanirwa kurongeka zvine musoro. Kuputika kweparamita kunofanirwa kuve kwakatemwa nesainzi zvichienderana nechimiro chembiru uye zvimiro zveore kudzivirira kuputika kusakonzera kukanganisa kwakanyanya pambiru nedombo rakatenderedza. Maitiro ekubvisa ore anofanirwa kurongeka zvakarongeka kudzivirira kuunganidzwa kweore, izvo zvinogona kukanganisa mashandiro anotevera uye kuderedza kushanda zvakanaka kwekugadzira. Semuyenzaniso, kukwidziridza nzvimbo yemakomba anoputika uye huwandu hwezvinoputika zvinochaji zvichienderana nekukora uye kuoma kwembiru dzakasiyana kunogona kuita kupatsanurwa kwakanaka uye kupora kwakachengeteka.
III.GobArea Processing
(1) Chinangwa
Chinangwa chikuru chegob area processing ndechekugoverazve kushushikana kwakadzikama, kuwana kuenzana kutsva mukushushikana kwedombo kuitira kuchengetedza uye kwakagadzikana mabasa emigodhi. Kana ikasiiwa isina kugadziriswa, kushushikana mupfungwa munzvimbo dzegob kunogona kukonzera kudonha kwedenga, kutamiswa kwedombo, uye dzimwe njodzi.
(2) Nzira Dzakafanana
Rock Caving: Zvinoputika zvinodonha zvakatenderedza dombo kuzadza nzvimbo dzegob, kuderedza kushushikana uye kugadzira buffer layer. Kudzika kwezvinhu zvakavharwa kunofanirwa kudarika 15-20 metres kuve nechokwadi chekuchengetedza. Nzira dzepamusoro dzekuputisa, dzakadai sekuputika kwakadzika-gomba, wedzera kushanda zvakanaka.
Backfill: Inokodzera kucherwa kwepamusoro-giredhi ore uye nzvimbo dzine zvakaomesesa pamusoro pekugadzikana zvinodiwa. Zvishandiso zvinosanganisira dombo remarara, jecha, miswe, uye kongiri. Kunyatsodzora backfill density uye kugovera kunowedzera simba rekutsigira.
Kuisa chisimbiso: Kugadzira madziro akakora ega ega mumatanho ekupinda kuti atore zvinoputika. Iyi inzira yechipiri, kunyanya yenzvimbo diki dzegob.
IV. Kuwirirana pakati pePillar Recovery uye Gob Area Processing
Maitiro acho anoenderana. Kudzoreredza mbiru kunokanganisa kugadzikana kwenzvimbo, sezvo kubvisa mbiru kunogovera kushushikana, zvichikonzera kudonha kwedenga uye dzimwe njodzi. Sezvineiwo, gob nharaunda kugadzirisa kunokanganisa kuchengetedzeka uye kugona kwembiru kudzoreredza. Nzvimbo dzakanyatsogadziriswa gob dzinoderedza kushushikana pambiru dzakasara, kufambisa mabasa akachengeteka.
Kurongeka kwekuita kunoenderana nezvinhu zvakaita sekushushikana chiitiko, orebody mamiriro, uye zvirongwa zvekugadzira. Semuyenzaniso, kushushikana kwakanyanya kunoda kuti gob nzvimbo igadziriswe kutanga, nepo dombo risina simba richida kudzoreredza mbiru panguva imwe chete uye kurapwa kwenzvimbo.
V. Zvidzidzo Zvakadzidzwa
Gadzirisa zvirongwa zvinoenderana nemamiriro ejoloji, uchishandisa emberi yekutarisisa maturusi eiyo chaiyo-nguva kushushikana uye kutamiswa kwekutevera.
Enzanisa uye nekunatsiridza akasiyana kudzoreredza uye gob nharaunda kugadzirisa maitiro ane simulation software kufanotaura mhedzisiro, kuderedza njodzi nekuvandudza mashandiro.
Izvi zvinogonesa kurongeka mbiru kudzoreredza uye gob nharaunda kugadzirisa, kuwedzera kuchengetedzeka kwemigodhi, kugadzira, uye kusimba.
