Since our first shaft-sinking project in Leadville, Colorado in 1969, Harrison Western has been providing underground mining development, construction, maintenance, closure, remediation, and contract mining services.

We expanded our line of services to heavy civil applications, such as above-ground drilling and blasting, rockfall mitigation and stabilization, rock scaling and cutting, expansive grouting, shotcreting, and shoring.

In 2014, Harrison Western acquired Underground Infrastructure Technologies, who offers auger boring, microtunneling, conventional hand tunneling, and pipe jacking, ramming, and bursting.
