Emkhathini oguqukayo njalo wobuchwepheshe bezimayini, ukubhola kwamadwala kuye kwavela njengamathuluzi abalulekile kukho kokubili ukusebenza okungaphezulu nangaphansi komhlaba. Njengoba izimfuno zezimayini zikhula futhi ukufuna ukusebenza kahle kwanda, izinkampani ezifana ne-Sunward zihamba phambili ekuletheni izixazululo ezintsha zokubhekana nalezi zinselele. Isungulwe ngo-1999 nguSolwazi ongumboni u-He Qinghua, iSunward izizakhele indawo esizindeni semishini yokwakha yomhlaba. Ngesisekelo esiqinile ocwaningweni nakwezobuchwepheshe, le nkampani isibe umholi emkhakheni wemishini yobunjiniyela.
I-Sunward igqamile hhayi kuphela ngokuzibophezela kwayo ekuthuthukisweni kwezobuchwepheshe kodwa futhi nangohlelo oluhlaba umxhwele lwemikhiqizo eklanyelwe imboni yezimayini. Phakathi kohlu olubanzi lwemishini, iloli lokulahla izimayini i-SWK105Z ikhanya njengempahla ebalulekile ekuthuthweni kwezinto zokwakha, kuyilapho amamodeli e-SWDE120B kanye ne-SWDQ120 enikeza ukusebenza okukhethekile emisebenzini ehlukahlukene yezimayini. Lezi zimoto ziklanywe ngobunjiniyela obuqinile, obuqinisekisa ukuqina nokusebenza kahle endaweni enzima yezimayini. Ngaphezu kwalokho, amamodeli e-SWDF138 kanye ne-SWDB165 ahlinzeka ngamakhono athuthukile, aqinisekisa ukuzinikela kuka-Sunward ekukhiqizeni nasekusungulweni kwekhwalithi ephezulu.
Ingxenye ye-rock drilling rig yilapho i-Sunward iphumelela ngempela. Ngesabelo sayo esiphezulu semakethe e-China, izivivinyo ze-rock zenkampani zenzelwe ukusebenza okuphezulu, ukwethembeka, nokuphepha. Lawa ma-drill aklanyelwe ukubhekana nezimo ezinzima kakhulu, okuwenza abaluleke kakhulu emisebenzini ehlukahlukene yezimayini. Ubuchwepheshe beSunward kule ndawo bubonakala ekuzinikeleni kwayo ukuqhubeka nokwenza ngcono kanye nokuthuthukisa imikhiqizo yayo ukuze ihlangabezane nezidingo eziguqukayo zemboni.
Njengoba umkhakha wezimayini uya ngokuya uncintisana, isidingo semishini esebenza kahle, ethembekile, futhi esebenza kahle sibaluleke kakhulu kunangaphambili. I-Sunward iyasibona lesi sidingo futhi isabela ngezisombululo ezisezingeni eliphezulu ezingagcini nje ngokuthuthukisa umkhiqizo kodwa futhi ezifaka isandla ekuphepheni kukonke nasekusimameni kwemisebenzi yezimayini. Ukuhlanganiswa kobuchwepheshe obuthuthukisiwe kuma-rock drills abo kuqinisekisa ukuthi amakhasimende athola okokusebenza okukhulisa ukusebenza kahle kokusebenza kuyilapho kunciphisa isikhathi sokuphumula kanye nezindleko zokunakekela.
Ngaphezu kokuklama kwayo kwe-rock, ukuzibophezela kwe-Sunward kwikhwalithi kubonakala kusevisi yayo ebanzi yangemva kokuthengisa nokwesekwa. Le nkampani ikholelwa ekwakheni ubudlelwano besikhathi eside namakhasimende ayo ngokuhlinzeka ngosizo oluqhubekayo nokuqinisekisa ukuthi okokusebenza kwayo kusebenza ngendlela esezingeni eliphakeme kuwo wonke umjikelezo wayo wokuphila. Le ndlela yokwenza isiqinise isithunzi sika-Sunward njengozakwethu onokwethenjelwa embonini yezimayini.
Uma sibheka phambili, uSunward usalokhu egxile ekugcineni isikhundla sakhe njengomholi emkhakheni wemishini yobunjiniyela. Ngezinhlelo eziqhubekayo zocwaningo nentuthuko, inkampani isilungele ukwethula ubuchwepheshe obusezingeni eliphezulu kakhulu kanye nemikhiqizo ezochaza kabusha amakhono okubhola kwamadwala nezinye izinto zokusebenza zezimayini. Njengoba imboni iqhubekela phambili ekusebenzeni okuzenzakalelayo nokusebenza kahle, uSunward uzibophezele ekubeni phambili kulezi zinguquko.
Sengiphetha, ama-rock drill adlala indima ebalulekile empumelelweni yezimayini, futhi u-Sunward uzinikele ekuthuthukiseni amakhono abo ngezisombululo ezintsha. Ngefa lobuhle kanye nendlela yokucabanga phambili, u-Sunward uyaqhubeka nokuhola indlela ekuletheni imishini yezimayini yesimanje ehlangabezana nezidingo ezihlala zivela embonini. Ezinhlanganweni ezifuna ukutshala imali ekuzilolongeni kwedwala kwekhwalithi ephezulu namathuluzi ahlobene, i-Sunward ngokungangabazeki iwuphawu okufanele lucatshangelwe.
