Raisebore mine shafts provide a safer and more efficient method for constructing ventilation and mine access shafts. Miller specializes in raisebore shaft construction, delivering rapid, precise solutions that create fully operational mine shafts while minimizing risks and project timelines.
We own and operate industry-leading raisebore equipment, giving us full control over mobilization, scheduling, and costs. This eliminates delays associated with third-party equipment, ensuring faster execution and cost savings. Our in-house expertise and equipment allow us to complete raisebore mine shaft projects with the highest level of safety.
Raisebore mine shaft construction begins underground, starting with a pilot hole drilled from the surface to the mine level. A reaming head is then pulled upward, enlarging the hole to the desired diameter. This method is faster and safer than conventional sinking, especially for smaller shafts, making it ideal for ventilation and access shafts. It is particularly suited for mine shafts under 24 feet in diameter and requires the mine to be developed under the shaft location.
At Miller, we take care of every phase of the process, ensuring precise execution while maintaining the highest safety standards.

At Miller Contracting, we specialize in providing efficient and precise raisebore mine shaft construction services. With our in-house ownership of raisebore rigs, we are able to offer faster mobilization and more control over project timelines. This allows for greater cost savings compared to contractors who rely on third-party equipment. It also allows us to keep operations streamlined and avoid delays that can impact the overall project schedule.
Safety and quality are our top priorities. We have built a reputation for delivering raisebore projects that meet or exceed MSHA safety standards. Our team’s expertise in managing complex underground mine conditions ensures that your raisebore shaft will be constructed safely, on time, and with minimal disruption to ongoing operations. With a 99.9 percent on-time completion rate and an 80 percent repeat customer rate, Miller is the trusted choice for raisebore mine shaft construction.
Our integrated approach allows us to handle every aspect of the project, from pilot hole drilling to final shaft lining and ventilation system installation. While other firms may specialize in only part of the process, we provide a full turn-key solution, ensuring smoother coordination, better project control, and fewer risks. Miller’s extensive experience and commitment to continuous improvement ensure that we deliver high-quality raisebore shafts that are built to last.
Miller’s ownership of advanced raisebore equipment enables us to complete your mine shaft project with greater speed and safety, reducing risks and delivering cost savings at every stage
Raisebore mine shaft construction involves drilling a pilot hole from the surface to an underground mine level and then reaming the hole upward to the full diameter. This method is faster and safer compared to conventional shaft sinking.
Raisebore shafts are ideal for smaller mine shafts, such as ventilation or secondary access. The method offers faster construction and greater safety since the reaming process is done from below the surface.
Raiseboring is typically used for ventilation shafts and secondary access shafts with diameters up to 24 feet. It’s ideal when there is already an underground mine level and the mine shaft does not need to be large.
Raisebore projects are typically completed faster than conventional sinking, especially for smaller mine shafts. Project timelines depend on depth, shaft diameter, and geological conditions.
