Izinkinga kanye nezinyathelo zokulwa nokwakhiwa kwenqwaba ejulile

1. Ukusebenza kahle kokwakhiwa kuphansi, ikakhulukazi ngenxa yesikhathi esiphezulu sokuphakamisa ithuluzi lokubhoboza kanye nokusebenza kahle okuphansi kwepayipi lokubhoboza ukudlulisa ukucindezela kokumba.
indlela yokubhekana nesimo:
(1) Khulisa ubude bebhithi yokubhoboza ukuze ukhuphule inani le-ballast ngakunye;
(2) I-drill bit ifakwe umoya wokuphakamisa isivinini sokumba;
(3) Uma ungekho edwaleni, zama ukusebenzisa ibha yokushayisana, ukuze ulondoloze isikhathi sokuvula.
2. Izinga lokuhluleka kwepayipi lokubhoboza likhuphuka kakhulu. Ngemuva kokwelulwa kwepayipi lokubhoboza, isilinganiso esincanyana sepayipi lokubhoboza alinangqondo ikakhulukazi, futhi ukwakhiwa kufanele kube ne-torque enkulu nokucindezela, ikakhulukazi ipayipi lokukhiya umshini livamise ukuvuleka phansi, ngakho-ke izinga lokwehluleka kwepayipi lokubhoboza lizokwazi vuka kakhulu.
indlela yokubhekana nesimo:
(1) Indawo okusetshenzwa kuyo kufanele ishelele futhi iqine ngangokunokwenzeka ukuze kuncishiswe ukushwibeka kwendawo yokumba;
(2) Lungisa uhlelo lokukala njalo ukuze wenze ipayipi lokubhoboza lisebenze libheke phezulu;
(3) Akuvunyelwe ngokuphelele ukugqekeza i-rig ngesikhathi sokumba okucindezelwe;
(4) Faka i-centralizer epayipini lokubhoboza.
3. Ukuchezuka kwembobo yenqwaba, isizathu esiyinhloko ubulukhuni obungalingani nobulukhuni bokubunjwa, ukuncishiswa kwensimbi sekukonke ngemva kokwelulwa kwenduku yokubhoboza, kanye negebe elikhulayo lethuluzi lokubhola ngemva kobude bethuluzi lokubhola.
indlela yokubhekana nesimo:
(1) Khulisa ubude bamathuluzi okumba;
(2) Faka indandatho ye-holrighizer endaweni yokubhoboza;
(3) Engeza idivayisi ye-counterweight engxenyeni engenhla ye-drill bit, futhi usebenzise ukucindezela phansi kwembobo, ukuze ithuluzi lokubhoboza libe nomsebenzi wokuzisekela lapho ubhoboza.
4. Izingozi ezivame ukuvela emgodini, ikakhulukazi ezibonakala ngokuwa okungazinzile kodonga lwembobo.
indlela yokubhekana nesimo:
(1) Ngenxa yesikhathi eside sokwakhiwa kwenqwaba ejulile, uma umphumela wokuvikela udonga ungemuhle, udonga lwembobo luzontengantenga, futhi udaka olusezingeni eliphezulu kufanele lulungiswe;
(2) I-drill bit ine-vent yokunciphisa umthelela kanye nokudonsa odongeni lwembobo lapho ubhoboza.
