The San Jose Mine Rescue : An Overview of Plan A

CIM Montreal 2011
Abstract The Cementation group and their Chilean partner Terraservice were involved in the mine rescue program at the San Jose mine in Chile. The Terraservice group was the first drilling contractor to break a hole through to confirm that the workers were alive. Terracem(a partnership company between Cementation and Terraservice) is a Chilean based raise boring contractor with shop facilities in Copaipo. The group mobilized a Strata 950 raise bore machine immediately to carry out the Plan A drilling program. This presentation gives a brief overview of that drilling program.
