Stage 3 Diamond Coring Bit Field Tested - Extend, Improve, Exceed

Drill Crews experimenta un 300% de aumento en la vida útil de los bits

At a nickel mine in Manitoba, Canada, Boart Longyear Drilling Services field tested the new Stage 3 25mm diamond coring bit in a multi-site deployment. Drill crews experienced bit life gains of up to 300% over their previous standard 12mm crown.

Boart Longyear Drilling Services ha empleado brocas de 12 mm durante más de tres años en una mina de níquel en Manitoba, Canadá. Las condiciones del suelo son exigentes debido a la variabilidad en la formación, no sólo de una parte de la mina a la otra, sino incluso dentro de un mismo agujero. Las formaciones en Manitoba son típicamente de cuarzo abrasivo duro mezclado con tierra semi dura y de grano grueso.

Hasta hace poco, la fórmula 08ABR de 12 mm había demostrado ser la mejor en uso en la mina con una vida útil promedio de 37,5 metros.

 

Prolongación de la vida útil de la broca en suelos duros y abrasivos

With the proven performance of the 12mm crown, the drilling crews were unsure about trying the new 25mm Stage 3. Boart Longyear field engineers knew that upgrading to the Stage 3 would provide a significant performance increase. Engineers delivered the bits to the drill crews in the 08ABR formula.

La vida de la broca se triplica

After putting the bits to the test, the drill crews were stunned by the 25mm Stage 3 results. The average bit life of the Stage 3 was 120 meters—more than three times the life of the 12mm crown.

As more Stage 3 bits are deployed in the field, the results continues to prove what drillers and mine operators are saying: “Boart Longyear has delivered another industry first.”
