Zomwe Zimakhudza Kuchita Mwachangu kwa DTH

Dongosolo la DTH (Down-The-Hole) limatanthawuza chida chapadera chobowola chomwe chimagwiritsidwa ntchito m'migodi, zomangamanga, ndi mafakitale amafuta ndi gasi. Amapangidwa kuti amangiridwe ku nyundo ya DTH ndikugwiritsidwa ntchito pobowola pansi.

Kuphatikiza pa kusankhidwa koyenera kwa ma carbide opangidwa ndi simenti, mphamvu ya kubowola kwa DTH imakhudzidwanso ndi zinthu zambiri, kubowola kumatha kuwonedwa makamaka pakuwunika mosamala. Maonekedwe a bowolo ndi osiyana, ndipo gawo la dzenje lophulika lomwe limapezeka pamene kubowola limakhala losiyana.

1. Bowola mawonekedwe

Mawonekedwe a kubowola amakhudza mwachindunji gawo la dzenje lophulika. Gawo lophulika la mabowo ambiri ndi polygonal, osati kuzungulira. Choncho, gawo la polygonal limapangidwa chifukwa cha kupatuka kwa bowolo kumbali imodzi ya dzenje lophulika pamene likuzungulira mozungulira. Pobowola, ndodo yobowolayo simazungulira pa oxis wokhazikika koma imazungulira momasuka mubowo.

2. Thanthwe katundu

Makhalidwe a thanthwe omwe amakhudza liwiro laling'ono kwambiri ndi kukhuthala, kulimba, ndi kukhazikika. Kukakamira kwa thanthwe ndiko kuthekera kwa thanthwe kukana kusweka mu tiziduswa tating'ono. Makhalidwe a miyala amagwirizana ndi mapangidwe ndi mapangidwe a thanthwe; kukula kochepa ndi mawonekedwe a particles; ndi kuchuluka, kapangidwe kake, ndi chinyezi cha simentiyo. Miyala yolimba komanso yofanana imakhala ndi mamasukidwe ofanana mbali zonse, ndipo miyala yosakanikirana kapena yosanjikiza imakhala ndi kukhuthala kosiyana mbali zonse. Kuuma kwa thanthwe, monga mamasukidwe akayendedwe, kumatsimikiziridwa ndi mphamvu yolumikizana pakati pa miyala. Komabe, kuuma kwa mwala ndiko kutha kukana zida zakuthwa zolowera mkati mwake. Kutanuka kwa thanthwe kumatanthawuza mphamvu yake yobwezeretsa mawonekedwe ake oyambirira ndi voliyumu pambuyo pa mphamvu yakunja yomwe ikugwira ntchitoyo itatha. Miyala yonse ndi yotanuka. Kutanuka kwa thanthwe kumakhudza kwambiri momwe kubowola kumakhudzira.
