Our Underground Face Drilling service provides a fundamental and highly specialized function within the advancement of underground mines and tunnels. It involves the precise drilling of blast holes in the active working face, which is the leading edge of excavation. This critical process is essential for both the creation of development headings, such as drifts (horizontal access tunnels) and ramps (inclined roadways), as well as for the execution of production rounds aimed at extracting ore or other valuable materials. The accuracy and efficiency of our face drilling operations directly impact the rate of advance, the effectiveness of subsequent blasting, and the overall productivity of the underground project.

Our experienced team of underground drillers utilizes a range of specialized drilling equipment, including pneumatic and hydraulic drill rigs, specifically designed for the confined and challenging environment of underground workings. We are proficient in operating both single and multi-boom drill jumbos, allowing for efficient drilling of multiple blast holes simultaneously, thereby accelerating the drilling cycle. Our drillers are highly skilled in interpreting drilling plans and adhering to specific patterns that are engineered to achieve optimal rock fragmentation during blasting. These patterns take into account the geological characteristics of the rock mass, the desired advance per blast, and safety considerations.  

Precision is paramount in our Underground Face Drilling operations. We ensure that blast holes are drilled to the correct depth, diameter, and angle as specified in the drilling plan. Deviations from these specifications can lead to poor fragmentation, overbreak or underbreak of the excavation, and potential safety hazards. To achieve this accuracy, our drillers utilize various alignment tools and techniques, and we maintain our drilling equipment to the highest standards of operational readiness and calibration.

Our service is integral to the cyclical nature of underground excavation. Following a blast, our team moves in to muck out the broken rock, and then our face drilling crew prepares the newly exposed face for the next blast round. This efficient and well-coordinated process is crucial for maintaining a consistent rate of advance in development headings and ensuring the timely extraction of ore in production areas. We prioritize safety in all our drilling operations, adhering to strict protocols for equipment operation, ground support interaction, and working around explosives. By entrusting your underground face drilling needs to our expertise, you can be confident in achieving accurate, efficient, and safe drilling that directly contributes to the successful progress of your underground mining or tunneling project.
