CAUSES OF DRILL ROD FAILURE

In the third part of this series we examine a very important aspect of a drilling operation - the failure of drill rods or drillpipe.

Why drill rods and drillpipe fail

In diamond drilling operations, the drillstring is rotated at extremely high rotational speeds and the consequences of a drill rod failure can be catastrophic particularly if the drill rod that fails is a quillrod.

Read this article to gain an understanding of the modes of failure of drill rods.

The quillrod is an irreplaceable part of a drilling operation, therefore a thorough understanding of the causes of quillrod failure is essential in preventing these incidents.

Pro-active detection of potential drill rod failure should be a key element of day-to-day drill site safety management, however, quillrod management is complicated by the different procedures used by different contractors.

CARE AND MAINTENANCE OF WIRELINE DRILL RODS

Drill rods and drill pipe are an extremely expensive part of the drilling operation and so correct break in and maintenance procedures are essential for long life. 

FOCUS AREA 2: WIRE ROPE
INSPECTION AND DISCARD STANDARDS

In the second part of this series we explore the importance of wire rope inspection, the various rope defects that could occur as well as provide some essential guidance on wire rope discard standards.

Diligent inspection of wire ropes is an essential part of a pre-start and daily inspection system. 

WIRE ROPE DEFECTS
WIRE ROPE DEFECTS

Wire rope will develop defects during use through several different mechanisms each of which will affect the strength of the rope and therefore limit the working life of the rope.

It is not possible to look at a wire rope and determine its strength. We therefore need to have strict standards to determine when a wire rope should be discarded.
