Isishwankathelo
Kwindlela yokutsalwa okwesibini eyaziwa ngokuba yimigodi emide, ubuso bomgodi obude (ngokuqhelekileyo kuluhlu oluyi-100 ukuya kuma-300m kodwa lunokuba lude) lwenziwa ngokuqhuba indlela yendlela kwii-engile ezichanekileyo phakathi kweendlela ezimbini ezenza amacala ebloko emide. ubambo olunye lwale ndlela intsha yenza ubuso obude. Nje ukuba kufakwe isixhobo sobuso belongwall, amalahle anokukhutshwa kubude obugcweleyo bobuso kwiziqwenga zobubanzi obunikiweyo (ekubhekiselwa kubo njenge "web" yamalahle). Ubuso be-longwall banamhlanje buxhaswa yinkxaso ye-hydraulically powered kwaye ezi zixhaso zihanjiswa ngokuqhubekayo ukuxhasa ubuso obusanda kukhutshwa njengoko kuthatyathwa izilayi, ukuvumela icandelo apho amalahle aye agrunjwa ngaphambili kwaye axhaswa ukuba adilike (ebeyibhokhwe). Le nkqubo iphindwa ngokuqhubekayo, iwebhu ngewebhu, ngaloo ndlela isusa ngokupheleleyo ibhloko yoxande lwamalahle, ubude bebhloko kuxhomekeke kwizinto ezininzi (jonga amanqaku kamva)
Inkqubo yokuthuthwa kwamalahle ifakwe ebusweni, kubuso bale mihla "isixhobo sokuhambisa ubuso esixhobileyo okanye i-AFC". Iindlela ezenza amacala ebloko zibizwa ngokuba zii "gate roads". Indlela yendlela apho indawo yokuhambisa ipaneli engundoqo ifakwe kuyo kubhekiselwa kuyo njenge "main gate" (okanye "maingate"), kunye nendlela yendlela kwelinye icala ekubhekiselwa kuyo njenge "tail gate" (okanye "tailgate") yendlela.
Iingenelo zokumbiwa kwemigodi emide xa kuthelekiswa nezinye iindlela zokutsalwa kwentsika zezi:
• Iinkxaso ezisisigxina zifuneka kuphela kwisahlulo sokuqala sokusebenza kwaye ngexesha lofakelo kunye nemisebenzi yokubuyisela. Ezinye izixhaso zophahla (i-longwall chocks okanye amakhaka kwii-longwall zanamhlanje) ziyasuswa kwaye zihanjiswe kunye nezixhobo zobuso.
• Ukubuyiswa kobutyebi kuphezulu kakhulu - ngokwethiyori i-100% yebhloko yamalahle ekhutshwayo, nangona enyanisweni kukho ukuchitheka kwamalahle okanye ukuvuza kwindlela yokuthuthwa kobuso kulahleke kwibhokhwe, ngakumbi ukuba kukho amanzi amaninzi kwibhokhwe. ubuso
• Iinkqubo zokumbiwa kwe-Longwall ziyakwazi ukuvelisa iziphumo ezibalulekileyo kubuso obunye be-longwall-i-8 yezigidi zeetoni ngonyaka nangaphezulu.
• Xa esebenza ngokuchanekileyo amalahle embiwa ngendlela ecwangcisiweyo, eqhubekayo nephindaphindwayo nelungele ulawulo lwestrata kunye nemisebenzi yokwembiwa ehambelanayo.
• Iindleko zabasebenzi/iitoni eziveliswayo zisezantsi noko
Izinto ezingeloncedo zezi:
• Kukho ixabiso eliphezulu lenkunzi yezixhobo zokusebenza, nangona lingekho phezulu njengoko libonakala kuqala xa lithelekiswa nenani leeyunithi eziqhubekayo zabasebenzi basezimayini eziya kufuneka ukuvelisa imveliso efanayo.
• Imisebenzi igxile kakhulu ("onke amaqanda kwibhaskithi enye").
• I-Longwalls ayiguquguquki kakhulu kwaye "ayixoleli" - ayikuphathi kakuhle ukupheliswa komthungo; iindlela zesango kufuneka ziqhutywe kwimigangatho ephezulu okanye iingxaki ziya kuvela; iimeko ezintle zobuso zihlala zixhomekeke kwimveliso ibe ngaphezulu okanye kancinane eqhubelekayo, ngoko ke iingxaki ezibangela ulibaziseko zinokudityaniswa zibe ziziganeko ezinkulu.
• Ngenxa yokungaxoleli kweelongwall, umsebenzi onamava ubalulekile kwimisebenzi eyimpumelelo.
Isigqibo esikhulu ekufuneka senziwe ubukhulu beebhloko ezinde. Ngenxa yokuba ii-longwall zanamhlanje zibandakanya inani elikhulu lezixhobo zezixhobo (amanani obungakanani bezinto ezingamakhulu aliqela, ezinamacandelo amaninzi anobunzima obufikelela kwiitoni ezingama-30 okanye ngaphezulu), inkqubo yokubuyisela isixhobo kwibhloko egqityiweyo, ukusiwa kwibhloko entsha. kwaye emva koko ukuyifaka kwibhloko entsha (ehlala ikhutshwa kakhulu emgodini ukuze ilungiswe endleleni) ngumsebenzi omkhulu kakhulu. Ngaphandle kweendleko ezithe ngqo ezibandakanyekayo, imveliso kwaye yiloo nto ingeniso ingu-zero ngeli xesha. Iibhloko ezinkulu ze-longwall ziya kwenza ukuba inani lokufuduswa lincitshiswe, nangona kunjalo kukho imida yezinto kubungakanani beebhloko ezinde:
• Okukhona ubuso buthatha ixesha elide kokukhona kufuneka amandla angakumbi kwinkqubo yokuthuthwa kwamalahle (jonga amanqaku kamva ngee-AFC's). Amandla amakhulu, ubukhulu bomzimba weeyunithi zokuqhuba (ngokuqhelekileyo kukho iyunithi yokuqhuba kuzo zombini iziphelo zobuso). Iiyunithi zokuqhuba kufuneka zingene kumbiwa kwaye zivumele indawo yokufikelela ngaphaya kwazo, ukuze kungene impepho ebusweni kunye nakwinqanaba elithile lophahla ukuya kokuvalwa komgangatho. Kwakhona amandla amakhulu, amakhulu (kwaye ke anzima) iamakhonkco emigodikwi-conveyor yobuso - la matyathanga ekhonkco entsimbi ajikelezayo kufuneka aphathwe ngobuso ngamanye amaxesha kwaye kukho ukulinganiselwa okusebenzayo malunga nobukhulu bamatyathanga emigodi.
• Kolunye ufakelo olude, ubushushu obudalwe zizixhobo zokuthutha amandla aphezulu bunokuba ngumba.
• Bobabini ububanzi nobude bobuso bunokulawulwa yimida edalwe yimida yengqeshiso, ukungaqhubeki komthungo okanye ukwahluka, uphuhliso olusele lukhona lwasemgodini kunye/okanye umthamo wokungenisa umoya.
• Ukukwazi komgodi ukuphuhlisa iibhloko ezintsha ezinde ukuze ukuqhubeka kwemveliso ende kungachaphazeleki kakubi.
• Umqathango wesixhobo – ukutshintsha ezinye izinto ukuze zilungiswe okanye zitshintshwe ngexesha lobomi bebloko elide kunokuba yingxaki, kwaye kwenziwa ngcono ngexesha lokufuduswa.
