Ibholithi yophahla, ekwabizwa ngokuba yi-anchor drilling rig kwezinye iindawo, sisixhobo sokugrumba kumsebenzi wenkxaso yebholithi kwindlela yomgodi wamalahle. Ineenzuzo ezibalaseleyo ekuphuculeni umphumo wenkxaso, ukunciphisa iindleko zenkxaso, ukukhawulezisa ukwakhiwa kweendlela, ukunciphisa umthamo wothutho oncedisayo, ukunciphisa amandla omsebenzi kunye nokuphucula umlinganiselo wokusetyenziswa kwecandelo leendlela. I-Bolt drill sisixhobo esiphambili senkxaso yebholt. Ichaphazela umgangatho wenkxaso yebholithi, njengokuqhelaniswa, ubunzulu, ukuchaneka kobubanzi bomngxuma kunye nomgangatho wofakelo lwebholiti, kwaye ibandakanya ukhuseleko lomntu lwabaqhubi, ukuqina kwabasebenzi kunye neemeko zokusebenza.
