One of the burning environmental issues related to Pennsylvania’s deep mining history, is on-going coal mine fires. Mine fires are a fairly common occurrence throughout the bituminous and anthracite coal mining regions and present a multitude of environmental and safety concerns. Mine fires, with a nearly limitless supply of fuel, can burn for decades without active 3rd party intervention.
Howard Concrete Pumping’s innovative drilling and grouting techniques have been used on numerous occasions to fight these difficult-to-extinguish fires. In some cases, we have used both cementitous grouts and fire-fighting foam to put-out these fires. Additionally,
Concrete Pumping has recently developed a patent-pending grout nozzle for the remote installation of mine seals from the surface. Remote mine seals prevent air from contributing to the spread of the fire, or can act as dams to quench actively burning underground areas.
