Izinsimbi zensimbizidlale indima ebalulekile ekwakheni ingqalasizinda yomhlaba, zaguqula ezokuthutha futhi zenza kube lula ukukhula komnotho. Kusukela ezinsukwini zokuqala zeNguquko Yezimboni kuya enkathini yanamuhla, ukuvela kwezitimela zensimbi kube ubufakazi bobuhlakani bomuntu kanye nekhono lobunjiniyela.
Umlando wezitimela zensimbi ungalandelwa emuva ekuqaleni kwekhulu le-19 lapho isidingo sezinhlelo zokuhamba ezisebenzayo sakhuthaza ukuthuthukiswa kwezitimela. Ngaphambi kokwethulwa kwezitimela zensimbi, izitimela zokhuni zazivame ukusetshenziswa, kodwa zazivame ukuguguleka, zinciphisa isivinini kanye nomthamo wezitimela. Ukufika kwezitimela zensimbi kwaphawula intuthuko enkulu, njengoba zazinikeza ukuqina okuphezulu namandla, okuvumela ukwanda kwamanethiwekhi ezitimela kanye nokuthuthwa kwemithwalo esindayo.
Ngesikhathi seNguquko Yezimboni, ukukhiqizwa kwemizila yensimbi kwathuthuka kakhulu, ngenxa yezinto ezintsha ezinqubweni zokukhiqiza insimbi. Inqubo yeBessemer, eyasungulwa ngawo-1850, yaguqula ukukhiqizwa kwensimbi ngokwenza kube lula ukukhiqizwa kwensimbi esezingeni eliphezulu ngentengo ephansi. Lokhu kuphumelela kwavula indlela yokwamukelwa kabanzi kwemizila yensimbi, njengoba yaba engabizi kakhulu futhi efinyeleleka kalula kumaphrojekthi okwakha izitimela.
Ukuqina nokuqina kweimigwaqoziye zaba usizo olukhulu ekwenzeni kube lula ukukhula kwezimboni kanye nezentengiselwano. Amandla ezitimela zensimbi ukumelana nemithwalo esindayo kanye nezimo zemvelo ezinzima azenze zaba usizo kakhulu ekuthuthweni kwezimpahla nabagibeli emabanga amakhulu. Ngenxa yalokho, izinhlelo zezitimela sezibe yingxenye ebalulekile yomnotho womhlaba, zisebenza njengomthombo wokuphila wezohwebo kanye nezentengiselwano.
Enkathini yanamuhla, ukuvela kwemizila yensimbi kuyaqhubeka nokuvela, kuqhutshwa intuthuko kwezesayensi yezinto zokwakha kanye nobunjiniyela. Ukuthuthukiswa kwezinsimbi zensimbi ezinamandla aphezulu kanye namasu okukhiqiza athuthukile kuye kwathuthukisa ukusebenza kanye nobude bemizila yensimbi. Lokhu kusungula izinto ezintsha kuye kwenza kwaba nokwenzeka ukwakhiwa kwamanethiwekhi esitimela asheshayo kanye nokwandiswa kwengqalasizinda yesitimela ukuze kuhlangatshezwane nezidingo zomhlaba oguquka ngokushesha.
Ukubaluleka kweizinsimbi zensimbiEzingqalasizinda zesimanje azinakweqiswa. Zakha umgogodla wezinhlelo zokuhamba, zixhumanisa amadolobha, izifunda, namazwe, futhi zenza kube lula ukuhamba kwabantu nezimpahla. Ngaphezu kwalokho, izinsimbi zensimbi zinegalelo emizamweni yokuzinza ngokunikeza indlela yokuhamba eyonga amandla, ukunciphisa ukukhishwa kwekhabhoni kanye nokunciphisa ukuminyana kwezimoto.
Uma sibheka phambili, ikusasa lemizila yensimbi linesithembiso sentuthuko enkulu nakakhulu. Imizamo yocwaningo nentuthuko igxile ekuthuthukiseni ukusebenza kahle kanye nokusimama kwezinhlelo zesitimela, kugxilwe kakhulu ekunciphiseni umthelela wemvelo kanye nokuthuthukisa ukusebenza kahle. Kusukela ekwamukelweni kobuchwepheshe besitimela obusha kuya ekusetshenzisweni kwezixazululo zengqalasizinda ehlakaniphile, ukuvela kwemizila yensimbi kulungele ukuqhubeka nokubumba isimo sezokuthutha kanye nezokuthutha.
Ekuphetheni, ukuvela kwemizila yensimbi kube uhambo olumangalisayo, kusukela ekuqaleni kwayo okuthobekile ngesikhathi seNguquko Yezimboni kuya endimeni yayo ebalulekile engqalasizinda yesimanje. Njengobufakazi bokusungula izinto ezintsha kanye nentuthuko yabantu, imizila yensimbi ishintshe indlela esixhumana futhi sihamba ngayo, yabeka imizila yesikhathi esizayo sezokuthutha ezisimeme nezisebenzayo.
