Ukuqonda iMigaqo ye-Mechanical ye-DTH Hammers kunye neeBits
Xa ugrumba kwiindlela zamatye aqinileyo,I-DTH (Phantsi koMngxuma) izando kunye neebhithi zokubhola dlala indima ebalulekileyo kwinkqubo yokomba. Ezi zixhobo ziyilelwe ukuba ziqhekeze ngokufanelekileyo kwiindlela eziqinileyo zamatye kunye nokubonelela ngezisombululo ezingabizi kakhulu kwiinkqubo ezahlukeneyo zokomba. Kule bhlog, siza kujonga ngakumbi ukuba njaniiihamile eziphantsi komngxuma kunye neebhithi zokubholaumsebenzi kunye nokubaluleka kwazo kushishino lokomba.
Ihamile ephantsi komngxuma kunye nebhithisebenza kunye ukwenza isixhobo esinamandla sokomba.Ihamile ye-DTH sisixhobo sempembelelo esisetyenziselwa ukunikezela ngokuvuthela okunamandla kwintwana yokomba, ngokwenza njalo ukwaphuka ukubunjwa kwamatye. Impembelelo iqhotyoshelwe kumphezulu wentambo ye-drill, kwaye xa ibetha i-drill bit, ivelisa amandla aphezulu empembelelo athunyelwa kwi-rock surface. Le mpembelelo yamandla yenza ukuba i-drill bit igqobhoze iliwa yenze umngxuma wokutsala amanzi.
Iimpembelelo eziphantsi komngxuma zisebenza ngokucinezela umoya okanye ezinye iincindi zokomba (njengamanzi okanye udaka) ukunika amandla impembelelo. Njengoko umoya oxinzelelweyo okanye ulwelo luhamba phantsi komtya we-drill, lungena kwi- impactor kwaye lwenza uthotho lwezithonga ezikhawulezayo, ezinamandla. Ezi zithonga zisebenza ngokuthe ngqo kwi-drill bit, ukuyivumela ukuba iqhekeze kwaye iqhekeze ukumila kwamatye. Ukusebenza kakuhle kweisando esisezantsi ngomngxumailele kumandla ayo okuhambisa amandla angaguqukiyo kunye nefuthe eliphezulu, iwenza ilungele iimeko zokomba ezinomngeni.
I-drill bit, kwelinye icala, licandelo eliphambili elisebenzisana ngokuthe ngqo nokwakhiwa kwamatye. Yenziwe ngezinto ezikwaziyo ukunxiba ezifana neencakuba ze-carbide ukumelana nokuguga nokukrazuka kokugrumba amatye. I-drill bit inoluhlu lwamaqhosha okanye amazinyo abekwe ngokucophelela ukuze enze isenzo sokusika xa ebethelwa ngehamile. Esi senzo sokusika, esidityaniswe namandla empembelelo yehamile, sivumela i-drill bit ukuba iqhekeze ngokufanelekileyo ilitye kwaye yenze umngxuma wobubanzi obufunwayo.
Olunye uncedo oluphambili lwesando esisezantsi-umngxuma kunye nenkqubo yentwana yokubhola kukukwazi ukugcina imingxuma yokugrumba ngokuthe tye kwaye ichanekile, naxa kusenziwa amatye aqinileyo. Amandla anempembelelo ephezulu eyenziwa yi-impactor iqinisekisa ukuba i-drill bit igcina isantya sokungena esingaguqukiyo, okubangela ukugaya okugudileyo kunye nokuchanekileyo. Oku kubaluleke ngakumbi kwizicelo ezifana nokwembiwa kwemigodi, ulwakhiwo kunye nokwembiwa kwe-geothermal, apho umgangatho wequla ubaluleke kakhulu kwimpumelelo yeprojekthi.
Ukongeza, i-DTH hammer kunye ne-drill bit systems zibonelela ngeendlela ezahlukeneyo kwimisebenzi yokomba. Ingasetyenziswa kwiindidi ezahlukeneyo zamatye, kubandakanywa ukwakheka okuqinileyo kunye ne-abrasive, apho ezinye iindlela zokomba zinokuba nzima ukufumana iziphumo ezinqwenelekayo. Oku kuguquguquka kwenza iihamile zomngxunya kunye neebhithi zokomba zibe zikhethelo ezithandwayo kwiiprojekthi ezahlukeneyo zokomba, ukusuka ekugrunjweni kwamanzi ukuya kuphononongo lwe-oyile negesi.
Ngamafutshane, iihamile eziphantsi komngxuma kunye neebhithi zokomba ziyinxalenye ebalulekileyo yoshishino lokomba, lubonelela ngezisombululo ezinamandla nezisebenzayo zokomba amatye aqinileyo. Ukukwazi kwabo ukuhambisa amandla anempembelelo ephezulu, ukugcina ukuchaneka kokomba kunye nokubonelela ngezinto ezahlukeneyo kubenza babe sisixhobo esiyimfuneko kwiinkqubo ezahlukeneyo zokomba. Ukuqonda indlela iihamile ze-DTH kunye ne-drill bits zisebenza ngayo kunceda ukuqonda ukubaluleka kwazo kwihlabathi lokomba kunye nendima yazo ekoyiseni iimeko ezinzima zokomba.
