San Jose Copper-Gold Mine, Copiapo,
Chile
On August 5, 2010, the roof of the
San José copper-gold mine collapsed,
leaving 33 miners trapped underground. The miners have set a world record for the length of time workers have survived trapped underground after a mining accident.
The San José Mine is about 45 kilometres
(28 mi) north of Copiapó, Chile. The
miners were trapped at approximately 700
metres (2,300 ft) deep and about 5
kilometres (3.1 mi) from the mine
entrance. The mine had a history of
instability that had led to previous
accidents, including one death. A
government report from July 2010 warned
that the mine owners had failed "to
reinforce the roof ...". The lack of
reinforcement "had led to [an earlier]
collapse of the roof." There has been
controversy over why the mine was not
closed down earlier. Source:

Rescue Plan
The widened shaft being drilled by the Schramm T130XD was completed on Saturday the 9th October even though it was stopped for approximately 10 hours due to a drill-bit change. As of October 8, 2010, the Strata 950 had reached 598 metres
deep (85%, still drilling its pilot
hole). The RIG-422, the only machine
which drills a shaft wide enough
immediately, reached 372 meters (62%).
Schramm T130XD Drilling Rig
The Schramm T130XD is a heavy duty, heavy hoist, carrier mounted drill rig. The T130XD utilizes the latest concepts in mast design and technology. Telescoping construction permits long head travel and working height to allow use of Range III casing, yet short overall length in the transport position. With a front overhang of less than 6 feet, the T130XD will get you to the jobsite when access roads require a compact machine.
Schramm, Inc. is a century-old Chester County, Pennsylvania manufacturer and global supplier to the hydraulic drill industry, focusing on land based applications. Source:
