UNDERGROUND DRILLING
RESEMIN MUKI FF rigs arrive in New Zealand
Federation Mining announced in early May 2023 that its narrow vein mining equipment has arrived in New Zealand for onward transport out to its Snowy River gold mine , located near Ikamatua on the West Coast of the South Island . It includes two RESEMIN MUKI FF drill jumbos ,
shipped from Peru . The MUKI FF is a front face electro-hydraulic drilling jumbo with a 1.05 m
width for tunnelling in underground mining in small sections from 1.5 x 2.0 up to 3.5 x 3.5 m . It also has an upper drill option for cut & fill mining on sections with a 1.5 m width at the bottom . It
comes with a hydraulic boom of square section and feed with options for working with : telescopic feed 8-10 , 6-10 and 6-8 feet . Another option is a simple feed with options for working with drill rods of 8 and 10 ft lengths . It is equipped with a Montabert drifter type HC 50 ( 14 kW ). The chassis is designed for heavy duty application , has articulated 4WD , a self-propelled diesel Deutz
engine and a Poclain hydrostatic transmission .
more expensive development drilling , reducing NPV for asset owners and decreasing margins for
contractors . Minnovare ’ s Development Optimiser™ system combines advanced
hardware with a digital platform to improve the drilling accuracy to ensure the drilling is as per the design .”
It says the system substantially improves drilling accuracy – leading to optimal blasts , reduced over-break / under-break and increased advance . Once the rail is aligned to the designed trajectory , the driller sets the ‘ TARGET ’ on the touch screen interface mounted inside the rig cabin – locking in the trajectory for every hole and removing all guess-work .
It “ delivers superior setup accuracy ” – the primary cause of blast-hole deviation ; maintains rail trajectory to designed target and parallelity between rails ; and works independently of laserline , levelling and other on-board rig alignment systems . Minnovare says it also integrates seamlessly with rig and mine planning / drill and blast software – for direct import and export of drilling data .
As part of a technology ecosystem it works via a wireless system interface together with Minnovare ’ s Client Online Reporting Engine ( CORE ), which includes digital drill plans ( Digi- Plan ) that capture all real-time drilling data , which can later be exported to mine planning software for analysis . Plus with Minnovare Smart Collar™ users can calculate new collar positions in realtime , with alignment precision to the planned toe ( if the originally marked collar is
obstructed due to rockbolts / space ).
