This article focuses on the key metrics in exploration diamond core drilling: safety performance, schedule, price, and quality core recovery. Safety programs ensure that wherever a Boart Longyear driller or driller assistant goes to work, the client can expect the same safe results. Safety is first.
Editor’s Note: This is the first in a two-part article on one operator’s perspective on performance drilling and how it can be used to improve efficiency and drive down costs. Look for a presentation on this topic by Graham Mensa-Wilmot, MAXDRILL (Performance Drilling) project leader with Chevron.
This paper examines the methods used to measure drilling efficiency and the difficulties encountered when using various data sources. The analysis examines the technologies used before, during, and after rotary rig operation which shape overall productivity results. The research also reviews the.
roper selection of the bit and speed of rotation of the drill for fast penetration and reduce the cost of drilling. Since the rock fragmentation process requires the drilling of small diameter holes for thplacement of explosive material, this makes the evaluation of rock properties' effect on.
Rock drill price analysis encompasses various factors that directly influence the cost-effectiveness of mining and construction operations. Modern rock drills combine advanced engineering with durability, featuring pneumatic or hydraulic systems that deliver powerful impact force for efficient rock.

6 FAQs about [How much is the qualified efficiency of Longyan rock drill]
Does rotary non-percussive drilling affect specific energy and rate of penetration?
In this study, a field-drilling test is performed using a rotary non-percussive drilling machine equipped with a new drilling-monitoring system to investigate the effects of drilling parameters on the specific energy (SE) and rate of penetration (ROP).
How does Boart Longyear Drilling Services Measure efficiencies?
Boart Longyear Drilling Services is currently measuring all the different increments that make up a 12-hour shift to find efficiencies in each of those individual steps – bit on bottom, charging the rods, wireline time, shift changes, transportation, mud programs, etc.
How can drilling companies improve efficiencies and lower costs?
The mining sector continues to look for ways to improve efficiencies and lower costs and drilling companies are following suit. At the end of the day, the best drilling contractors know that it’s all about providing maximum value to the customer. Drilling the meters is only one part of the equation and other metrics provide guidance to total value.
Does high ROP imply high drilling efficiency in practical engineering?
Note that high ROP does not imply high drilling efficiency in practical engineering because high ROP accelerates the wear of the drilling bit, thereby prolonging the drilling time. Furthermore, the drilling operators possess a few constraints in selecting the correct ROP parameters to optimize the drilling efficiency.
Does rotary non-percussive drilling cause rock failure?
According to the analysis on the SE values at different drilling conditions in rotary non-percussive drilling, the rock failure before the bit is more related to rotary shear than the axial force. Table 2. Calculation of SE based on different drilling parameters in the field test.
How long did it take Boart Longyear to complete drilling?
At week eight and only 1/3 of the way complete, Boart Longyear was called in and completed the remaining drilling for the project in only four weeks.
