Background to CTC
• Established in 1964 to present Engineering Learnership,
Mining and Coal Prep training exclusively to the coal
mines as a Chamber of Mines venture;
• Currently owned by a number of majors in the coalmining
business. Anglo American Thermal Coal; Glencore;
Exxaro; Shanduka and Kangra; South32 treated as a
shareholder.
• Owners pay a fixed subscription; private clients pay an
agreed rate;
• No profits taken from the business – reinvested in training;
• Capacity to train 760 learners per day in the engineering
workshops, 120 mining learners at Greenside and
Landau, 40 coal processing operators at CTC.

Background to CTC
• In addition to training, the coal mining industry has
entrusted us with important health and safety
functions:
• Collieries Environmental Control Services (CECS)
at Evander.
• Rescue Drill Unit (Google “CTC mine rescue” to see video clip of historic
event.)

Rescue Drill Unit - Background
• Coalbrook Disaster in 1960 cost 437 lives
• Chamber of Mines decided a suitable drill was required to
rescue people.
• First a Würth Machine was purchased in 1960’s – placed in
the care of a drill operator and was soon u/s.
• In 1977 Two Ingersoll Rand Machines were purchased. The
T4 and T5 Drillmasters. Housed at CTC up to 2014.
• By the late 1990’s this equipment was no longer supported
by the OEM.
• During 2010 the decision was taken to replace the
equipment.
• Steering committee established to oversee this process.
INTRODUCTION
• T4 165mm
• T5 750mm to 635mm

Problems to date….
• Casing insertion slower (but more accurate) than with old system.
(improving)
• Inner tube failures at Sigma hole. (Driconeq re-welded all tubes.)
• Penetration rate poorer than with old drill T5. (improving)
• Two piston failures on the RC210 NUMA hammer
(lubrication and ingress of debris were the issues with first piston)
• Bearing failure on the air inlet swivel (lubrication and rust as a
result of inactivity).
• Ageing fleet of truck-tractors can’t cope with long hauls over
mountains. (RDU Steercom agreed to replacement.)
• It proved impossible to lower the capsule down an inclined hole.
Due to step in hole diameter at bottom of casing.

Broken piston
• We need to drill more holes; large and small….
