Mine shaft sinking is critical to a profitable underground mining operation. It involves excavating vertical shafts to provide access to underground mining areas or to install essential systems such as ventilation and hoisting. Whether constructing a new mine access point or expanding an existing one, Miller’s expert team uses advanced techniques to ensure efficient, precise mine shaft sinking.
Sinking a mine shaft involves several key stages, including drilling, blasting, ground control, and lining. The process requires careful planning and execution to manage geological conditions, ground stability, and water control. Miller’s commitment to safety and operational efficiency ensures that your project will be completed safely, with minimal disruption to operations.
Blasting uses controlled explosives to break rock and create the necessary space for the mine shaft. This method efficiently handles the
excavation of hard or deep rock conditions where mechanical methods are impractical. It
ensures the mine shaft reaches the required diameter and depth, minimizing overbreak and preserving the surrounding rock. The controlled process accelerates excavation and keeps the
project on schedule, especially in challenging geological formations.
Ground Control involves installing support systems, such as steel sets or shotcrete, to stabilize the mine
shaft walls during excavation. This step is essential to prevent collapse, especially in unstable or weak rock formations. Ground Control ensures that excavation proceeds safely and without interruption, providing protection for workers and securing the mine shaft for subsequent lining and infrastructure installation.
Lining provides permanent structural support for the mine shaft by installing concrete or steel walls. It protects the shaft from environmental factors like water inflows and soil erosion, while also supporting the installation of essential systems such as hoists and ventilation. The lining ensures long-term stability, especially in geologically challenging environments, and maintains the integrity of the mine shaft throughout its operational life.

Conventional and raisebore mine shafts are essential to underground mine development. They provide critical access for personnel, materials, and ventilation systems while enabling deeper, more productive underground mining operations. At Miller, we construct both conventional shafts and raisebore shafts with precision, speed, and safety. Our team has decades of field experience with both types of mine shaft sinking projects.
Every underground mine is different. That’s why Miller offers both conventional shaft and raisebore shaft sinking methods. The best method will be selected based on site conditions, schedule, shaft diameter, and overall mine access requirements. Whether you’re establishing primary access or adding a ventilation shaft, we engineer the right solution for long-term safety and performance.
We own the mine shaft sinking equipment, and concrete services required to self-perform every phase of mine shaft construction. That control allows us to accelerate timelines, reduce costs, and deliver mine shafts that are built to operate safely under the most demanding conditions.
Miller is a trusted leader in mine shaft sinking. Our deep expertise in both conventional shaft and raisebore shaft sinking methods ensures that we can handle any project, regardless of geological conditions. We own three fully equipped shaft sinking systems, which allow us to mobilize faster and maintain better control over project timelines. Unlike competitors who rely on third-party equipment, our in-house systems help reduce costs and ensure more efficient project execution. With over 75 years of experience in the mining industry, we are known for our precision, safety, and ability to manage complex, high-risk mine sinking projects.

When you choose Miller for your mine shaft sinking project, you are partnering with a company that understands the complexities of underground mine
construction and is dedicated to providing a seamless, efficient, and safe experience from start to finish.
Miller offers expert mine shaft sinking services, managing every stage with precision to ensure safe, efficient access to underground mining production zones.
Mine shaft sinking is the process of excavating a vertical shaft to access underground mineral deposits or install essential systems like ventilation, hoisting, and water management. The process involves several stages, including drilling, blasting, shoring, and lining, to ensure a stable and safe mine access point for mining operations.
Mine shaft sinking is the process of creating vertical or inclined tunnels to access underground mines. It involves creating a shaft using either conventional mine shaft drilling methods or raisebore methods. Then, as the mine shaft is excavated, shoring and lining are installed to prevent collapse and ensure structural stability. Depending on the project, additional systems like hoists or ventilation may be installed within the shaft to support mining activities.
Sinking a mine shaft involves challenges such as dealing with unstable ground, managing water inflows, and ensuring the safety of workers. The depth and geological conditions of the site significantly impact the complexity of the sinking process. Proper planning and the use of specialized equipment are essential to overcoming these challenges.
The time required to sink a mine shaft depends on factors such as depth, diameter, geological conditions, and the chosen sinking method (conventional vs. raisebore). On average, sinking a mine shaft can take several months to a few years to complete, with regular monitoring to ensure safety and stability.
Specialized equipment such as drills, blasting tools, hoisting systems, and shoring equipment are used during mine shaft sinking. The type of equipment depends on the method chosen, whether conventional sinking or raisebore techniques. MILLER uses our own modern, specialized machinery to ensure efficiency and safety during the process.
Safety is a top priority in mine shaft sinking. Measures include thorough ground assessments, use of proper shoring techniques, continuous monitoring for stability, and adherence to strict safety regulations. The team also undergoes extensive training to handle hazardous conditions safely and ensure compliance with MSHA standards.
Geological conditions, such as unstable ground or high water inflows, can complicate the sinking process. At Miller, we conduct thorough site assessments and utilize advanced ground control techniques to manage these challenges, ensuring the mine shaft remains safe and stable throughout the sinking process.
