1. Ukubuka konke kwephrojekthi
Le phrojekthi isebenzisa ukwakhiwa okuvulekile. Uma ukujula komgodi wesisekelo kungaphezu kwamamitha ama-3 futhi kungaphansi kwamamitha ama-5, isakhiwo esisekelayo sisekelwa udonga olugcina amandla adonsela phansi lwenqwaba yesimende yokuxuba inhlabathi engu-φ0.7m*0.5m. Uma ukujula komgodi wesisekelo kungaphezu kwamamitha ama-5 futhi kungaphansi kwamamitha ayi-11, kusetshenziswa inqwaba eboshiwe engu-φ1.0m*1.2m + umugqa owodwa ongu-φ0.7m*0.5m. Ukusekelwa kwenqwaba yokuxuba inhlabathi yesimende kungaphezu kwamamitha ayi-11, kusetshenziswa inqwaba eboshiwe engu-φ1.2m*1.4m + umugqa owodwa ongu-φ0.7m*0.5m.
2. Ukubaluleka kokulawula ukuma okuqondile
Ukulawulwa kokuma kwezinqwaba kubaluleke kakhulu ekwakhiweni okulandelayo komgodi wesisekelo. Uma ukuphambuka kokuma kwezinqwaba ezibhobozekile ezizungeze umgodi wesisekelo kukhulu, kuzoholela ekucindezelekeni okungalingani kwesakhiwo sokugcina esizungeze umgodi wesisekelo, futhi kulethe izingozi ezinkulu ezifihliwe ekuphepheni komgodi wesisekelo. Ngesikhathi esifanayo, uma ukuphambuka kokuma kwenqwaba ebhobozekile kukhulu, kuzoba nethonya elikhulu ekwakhiweni nasekusetshenzisweni kwesakhiwo esiyinhloko esikhathini esizayo. Ngenxa yokuphambuka okukhulu kokuma kwenqwaba ebhobozekile ezungeze isakhiwo esiyinhloko, amandla azungeze isakhiwo esiyinhloko ngeke alingane, okuzoholela emifantwini esakhiweni esiyinhloko, futhi kulethe izingozi ezifihliwe ekusetshenzisweni okulandelayo kwesakhiwo esiyinhloko.
3. Isizathu sokuphambuka kokuma okuqondile
Ukuphambuka okuqondile kwenqwaba yokuhlola kukhulu. Ngokuhlaziya iphrojekthi yangempela, izizathu ezilandelayo zifingqiwe kusukela ekukhethweni kwemishini kuya ekwakhekeni komgodi wokugcina:
3.1. Ukukhethwa kwama-drill bits, ubulukhuni be-geological bomshini wokumba inqwaba ejikelezayo enqubweni yokubhoboza akuhambisani, ukukhethwa kwama-drill bits akukwazi ukuhlangabezana nezidingo zezimo ezahlukene ze-geological, okuholela ekuphambukeni kwama-bit, bese ukuphambuka okuqondile kwenqwaba kungahlangabezani nezidingo zencazelo.
3.2. Isilinda sokuvikela sigqitshwe endaweni yaso.
3.3. Ukugudluzwa kwepayipi lokubhoboza kwenzeka ngesikhathi sokubhoboza.
3.4. Indawo ebekwe kuyo ikheji lensimbi ayilungile, ngenxa yokungalungiselelwa kahle kwephedi ukulawula ikheji lensimbi, ukuphambuka okubangelwa ukwehluleka ukuhlola isikhungo ngemva kokuba ikheji lensimbi selikhona, ukuphambuka okubangelwa ukugeleza kukakhonkolo okusheshayo kakhulu noma ukuphambuka okubangelwa ipayipi elilenga ikheji lensimbi.
4. Izindlela zokulawula ukuphambuka kokuma
4.1. Ukukhethwa kwe-drill bit
Khetha izingcezu zokubhoboza ngokwezimo zokwakheka:
1 ubumba: khetha ingxenye engezansi yebhakede lokubhoboza elijikelezayo, uma ububanzi buncane ungasebenzisa amabhakede amabili noma ibhakede lokubhoboza elinomshini wokulayisha.
②Udaka, ungqimba lomhlabathi oluqinile, inhlabathi enesihlabathi, ungqimba lwamatshe ahlanganisiwe kabi olunobukhulu obuncane bezinhlayiya: khetha ibhakede lokubhoboza elinezansi ezimbili.
③Ubumba oluqinile: khetha indawo yokungena eyodwa (engaphansi eyodwa nephindwe kabili kungaba) ibhakede lokubhoboza elijikelezayo, noma amazinyo ebhakede isikulufu esiqondile.
Amatshe agqitshwe ngosimende kanye namatshe agugile kakhulu: kudingeka afakwe i-drill bit eyindilinga eyindilinga kanye nebhakede lokubhoboza elijikelezayo elingaphansi kabili (elinobubanzi obulodwa bobukhulu bezinhlayiya ezinkulu, elinobubanzi obuphindwe kabili)
⑤indawo yokubeka induku: ifakwe i-drill bit eyindilinga eyinhloko – i-conical spiral drill – ibhakede lokubhoboza elijikelezayo eliphindwe kabili, noma i-drill bit eqondile ejikelezayo – ibhakede lokubhoboza elijikelezayo eliphindwe kabili.
⑥Idwala elinomoya obandayo: lihlonyiswe nge-cone cone core drill bit – i-conical spiral drill bit – ibhakede lokubhoboza elijikelezayo elingaphansi kabili uma ububanzi bukhulu kakhulu ukuthi bungangena esiteji senqubo yokubhoboza.
4.2. Ibhokisi ligqitshwe
Ukuze kulondolozwe ukuma kwesilinda esivikelayo lapho kugqitshwa isilinda esivikelayo, ukulawulwa kwemigwaqo kufanele kwenziwe ngebanga elihlukile ukusuka enqwabeni eholayo kuya enkabeni yenqwaba kuze kube yilapho ingxenye ephezulu yesilinda esivikelayo ifinyelela ukuphakama okucacisiwe. Ngemva kokuba isilinda sesigqitshiwe, indawo ephakathi yenqwaba iyabuyiselwa ngaleli banga kanye nesiqondiso esinqunywe ngaphambilini, futhi kutholakale ukuthi isikhungo senqwabe sihambisana yini nesikhungo senqwabe, futhi silawulwa ngaphakathi kwebanga elingu-±5cm. Ngesikhathi esifanayo, indawo ezungezile yesilinda iyaqiniswa ukuqinisekisa ukuthi izinzile futhi ngeke ishintshe noma idilike ngesikhathi sokubhoboza.
4.3. Inqubo yokubhoboza
Inqwaba ebholiwe kufanele ibholwe kancane ngemva kokuvula imbobo, ukuze kwakheke ukuvikelwa kodonga okuhle nokuzinzile nokuqinisekisa indawo efanele yembobo. Ngesikhathi senqubo yokubhoboza, indawo yepayipi lokubhoboza ihlolwa njalo ngebanga elihlanganayo, futhi ukuphambuka kulungiswa ngokushesha kuze kube yilapho indawo yembobo ibekwe.
4.4. Ukubekwa kwekheji yensimbi
Ukutholwa kokuphambuka kokuma kwenqwaba kunqunywa ukuphambuka phakathi kwesikhungo sekheji lensimbi kanye nesikhungo senqwaba eklanyelwe, ngakho-ke indawo yekheji lensimbi iyinto ebalulekile ekulawuleni ukuphambuka kwesikhundla senqwaba.
(1) Kusetshenziswa imigoqo emibili yokulenga lapho ikheji lensimbi libekwa ngaphansi ukuqinisekisa ukuthi ikheji lensimbi liqondile ngemva kokuphakamisa.
(2) Ngokwezidingo zekhodi, kufanele kwengezwe iphedi yokuvikela, ikakhulukazi endaweni ephezulu yenqwaba kufanele kwengezwe iphedi yokuvikela.
(3) Ngemva kokuba ikheji lensimbi selifakwe emgodini, donsa umugqa ophambene ukuze uthole iphuzu eliphakathi nendawo, bese uqhuba ibanga phakathi kwesikhungo sendawo yokuhlangana kanye nokubuyiselwa kwenqwaba ngokudweba inqwaba kanye nesiqondiso esibekiwe. Qhathanisa umugqa oqondile olengayo nesikhungo sekheji lensimbi, bese ulungisa ikheji lensimbi ngokuhambisa kancane i-crane ukuqinisekisa ukuthi izikhungo ezimbili ziyahambisana, bese ushisela ibha yokuma ukuze wenze ibha yokuma ifinyelele odongeni lwesilinda esivikelayo.
(4) Uma ukhonkolo othululiwe useduze nekheji lensimbi, yehlisa ijubane lokuthulula ukhonkolo bese ugcina indawo ye-catheter maphakathi nomgodi.
