Ubomi bokudinwa kwee-Armored Face Conveyor (AFC) chains bubungqina obubalulekileyo bokuthembeka kwezixhobo kunye nokuveliswa kwamalahle kwimigodi ye-longwall. Ukusilela kwe-AFC kunye nee-chain-related kunokubangela malunga ne-27% yexesha lokungasebenzi, kwaye uxinzelelo olungafanelekanga lwe-mine chain luyimbangela ephambili. Eli phepha libonelela ngophando olunzulu malunga neendlela zokudinwa ze-ikhonkco elijikelezileyo kunye neekhonkco ezisicaba, iphonononga iindlela eziphambili zokuqikelela ubomi, kwaye inikezela ngeengcebiso zobugcisa ezijolise kubavelisi beenkqubo zemigodi kunye nabaqhubi bemigodi yamalahle. Injongo kukuphucula ubomi benkonzo yeenkqubo zemigodi ngokuphucula uyilo, ukubeka esweni okuphambili, kunye namaqhinga okugcinwa kwesayensi, ngaloo ndlela kuqinisekiswa ukusebenza kakuhle kwemveliso.
- Iintambo ezijikelezileyo zeLink: Zinoyilo olulinganayo noluguquguqukayo. Nangona kunjalo, indawo encinci yokunxibelelana phakathi kweekhonkco ibangela uxinzelelo olukhulu kakhulu lokunxibelelana kunye nokuguguleka kwendawo.
- Iintambo zeFlat Link: Izihlanganisi kwiinkqubo zeflat link zichongwa njengeendawo ezibuthathaka ezibalulekileyo. Uhlalutyo lweFinite Element (FEA) lubonisa ukuba uxinzelelo kwiintambo ezithe tyaba lugxila kwigxalaba lekhonkco, ukugoba kwangaphandle, kunye nengalo ethe tye yangaphakathi. Phantsi kwemithwalo efanayo, ukuguqulwa kwiindawo zoqhagamshelwano kwiintambo ezithe tyaba kunokuba malunga ne-1.9 yeendawo ezijikelezileyo, nto leyo eyenza ukuba zibe buthathaka ngakumbi ekugugeni kwendawo.
2.2 Iindlela zokuSilela okuPhambili
Ukungaphumeleli kokudinwa kubangelwa ziziphumo ezidibeneyo zoxinzelelo loomatshini, ukuguguleka, kunye nokuwohloka kwezinto:
- Ukuqhekeka Kokudinwa: Umthwalo ojikelezayo uqala ukuqhekeka okuncinci kwiindawo zoxinzelelo (umz., iindawo zoqhagamshelwano kwiindawo ezijikelezileyo, iingcambu zamazinyo ezidityanisiweyo kwiindawo ezithe tyaba), nto leyo ekhokelela ekuqhekekeni okubuthathaka. Uphando lubonisa ukuba ukuguguleka kutshintsha kakhulu ijiyometri yekhonkco, kukwandisa uxinzelelo kwaye kudala umjikelo "wokuguguleka nokudinwa" onobungozi.
- Ukuguguleka okurhabaxa: Indlela yokuguguleka ebalaseleyo ekhokelela ekulahlekelweni kwamacandelo ahlukeneyo kunye nokunciphisa amandla. Iindawo zokuguguleka ezibalulekileyo zifumaneka kwiindawo ezidityanisiweyo, kumphezulu we-arc yangaphandle, kunye necala langaphandle lamacandelo athe tye.
- Umthwalo omninzi kunye nempembelelo: Ukugcwala okugqithisileyo ngoko nangoko ngenxa yokutshintsha kweemeko zobuso (umz., i-jam) kunokubangela ukuguquka kweplastiki ngokuthe ngqo okanye ukwaphuka kweekhonkco zekhonkco.
2.3 Iindlela zokuqikelela ubomi obuphambili
Ukuqikelela okusekelwe kwikhompyutha ngoku kubalulekile kuphando nophuhliso.
- Uhlalutyo lweFinite Element (FEA): Ibala ngokuchanekileyo ukusasazwa koxinzelelo olulinganayo olutshintshanayo phantsi komthwalo, ivelisa iimephu ze-life contour ukuze ichonge ngokubonakalayo iindawo ezibuthathaka. Izifundo ziqinisekisa ukuba i-FEA inokwenzeka na ukuqikelela ubomi bokudinwa kwe-round link chain.
- Iimodeli zethiyori yomonakalo: Ithiyori yomonakalo eqokelelweyo eLinear (umz., uMthetho kaMiner) kunye nethiyori yokufana komonakalo zisetyenziswa kwimodeli yobomi betsheyini yomgodi. Le yokugqibela, ngokuseka ulwalamano neenkqubo zomonakalo ezaziwayo, inika imodeli esebenzayo yezibalo yokuvavanya ubomi betsheyini yonxibelelwano olujikelezayo phantsi kweespectra zomthwalo onzima.
- Ukuphucula iTopology kunye nokuKhawuleza: Sebenzisa i-topology eqhutywa yi-FEA elungiselelwe amakhonkco eetyathanga kunye nezihlanganisi (ingakumbi amazinyo ezihlanganisi ze-flat link) ukuze kufezekiswe ukusasazwa koxinzelelo olufanayo. Qinisekisa ukufana kunye nengqiqo yobomi bokudinwa kwiindlela ezilungisiweyo ngokubala.
- Isayensi yezinto kunye noTyando loBushushu: Ukwandisa umxholo wezinto ezixutyiweyo (Cr, Ni, Mn, Mo) kunye nokusebenzisa unyango lobushushu oluphuculweyo (umz., ukucima kunye nokushisa) kunokunyusa ukumelana nokuguguleka nge-10-25%. Kwiimeko ezinzima kakhulu, kufuneka kuqwalaselwe izinto ezikhethekileyo (umz., ukulwa nokugqwala) okanye amanqanaba entsimbi engagqwali.
- Ubunjineli bokuThembeka koQhagamshelano: Ii-Connectors kufuneka zihlangabezane neemfuno zamandla aphezulu, ukuhlukana, kunye nokuthetha. Uyilo kufuneka lulandele ngokungqongqo imigangatho efana ne-DIN 22258-3, kunye nokwenza ngcono kugxile ekufezekiseni ukusasazwa koxinzelelo ngokulinganayo kuzo zonke iinkqubo zamazinyo amaninzi—isitshixo sokuthembeka kwenkqubo iyonke.
3.2 Kubasebenzi beMigodi yamalahle: Ukubeka iliso ngobuchule, ukugcinwa, kunye nokuThenga
- Sebenzisa i-Intelligent Mining Chain Tension Monitoring: Iindlela zemveli zokuqonda uxinzelelo oluvela kumbane wemoto azichanekanga. Ukwamkelwa kweemitha zoxinzelelo ezikwi-intanethi ezifakwe kwiibha zokubhabha kuyacetyiswa ukuze kujongwe ukusasazwa koxinzelelo ngexesha langempela ebusweni. Ukudibanisa le datha kwinkqubo yolawulo lwe-longwall ukuze kulawulwe uxinezeleko oluzenzekelayo kubalulekile ekuthinteleni uxinezeleko olugqithisileyo okanye olungaphantsi.
- Misela uMgaqo woLondolozo oluQikelelweyo: Phuhlisa imodeli yokuqikelela ubomi obusele bekhonkrithi yemigodi ngokuhlanganisa idatha yoxinzelelo lwexesha langempela, ubungakanani bemveliso yembali, kunye nokuhlolwa rhoqo kweendawo zokuguguleka kwekhonkrithi. Oku kwenza kube lula ukucwangcisa utshintsho lwekhonkrithi ngokwesayensi, kuthintelwe ukutshintshwa kwangaphambi kwexesha kunye nokungaphumeleli okukhulu.
- Icebo Lokuthenga Nokusebenza Kwee-Ultra-Long Faces: Kwizixhobo zobuso ezidlula iimitha ezingama-400, ukucacisa ii-assembly ze-chain-and-flight ezilula, ulawulo olukrelekrele lwe-multi-drive synchronization, kunye neenkqubo zokuthutha ezithembeke kakhulu kufuneka zibe ziimfuno zobugcisa eziphambili ukujongana nemingeni efana namandla aphezulu okungenamthwalo, ukuqala okunzima kwemithwalo enzima, kunye nokuguga okukhawulezileyo.
