“Abandoned coal mines are a major cause for concern for the nearby communities here in Wyoming,” said Tony Martinez, Project Manager, Nicholson Construction. “We’re really happy to be out here with the AML team doing this exploratory work to find new mines that will eventually be grouted and help to protect the surrounding properties.”
In just the past three projects, the Nicholson team has contributed to the grout injection of roughly 26,000 cubic yards of grout. This injection of void-fill grout, under controlled low pressures, avoids additional damage to structures and infrastructure while reducing the hazards associated with mine subsidence to nearby communities.
Nicholson’s portion of this project also helped the State and the Engineers for the State to explore the depths and extent of rubblization and void spaces associated with historic underground coal mining for future void-fill grouting projects.
Work on this exploratory drilling project will wrap up for Nicholson in early October.
