Nau'o'in Hako Ma'adinai Daban-daban Da Haƙon Rijiya

Haƙar ma'adinai da rijiyoyin hakowa ramuka ne masu ban sha'awa waɗanda ke haƙawa ta hanyar shiga kayan dutse masu laushi da tauri. Ana amfani da su wajen haƙar ma'adinai, haƙon rijiyoyi, fasa dutse, tunnelling, gini, binciken ƙasa, da aikace-aikacen fashewa.

Haƙar ma'adinai da rijiyoyin hakowa yawanci suna nuna haɗin zaren don haɗawa da igiya mai raɗaɗi da rami mara ƙarfi ta inda ake zagayawa da ruwa mai raɗaɗi. Ana buƙatar ruwa mai tono don share yankan haƙora, sanyaya ɗan ƙaramin, da daidaita bangon rijiyar burtsatse. Nau'o'in hako rijiyoyin sun haɗa da:

Tri-cone ko abin nadiya ƙunshi mazugi masu haƙori guda uku, kowanne tare da kusurwar jarida da aka kafa zuwa ga babban axis na bit. An canza kusurwar jarida bisa ga taurin samuwar. Haƙoran kowane mazugi suna haɗaka da juna don su bi ta cikin ƙasa mai ƙarfi. Ma'aunin nauyi-on-bit (WOB) ne ke tafiyar da bitar yayin da ake jan shi ta aikin jujjuyawar shugaban bit bit.

Down-the-rami (DTH) gudumaana amfani da hamada na ƙasa-da-rami don haƙa ramuka ta nau'ikan duwatsu masu yawa. A haɗe tare da hammata na DTH, an ƙirƙira raƙuman guduma tare da splined drive don jujjuya bit a cikin ƙasa. DTH ragowa ne kafaffen kai waɗanda ke da juzu'i ko ƙugiya bit ɗin da aka haɗa a cikin matrix game da kan rawar rawar soja. Tsarin kai na bit yana iya zama maɗaukaki, maɗaukaki, ko lebur.
