Longitudinal Longhole
Used for narrow-veined ore deposits and can help reduce the cost of mining. Typically drilled with our Stinger drills due to their compact size (2 meter width). This allows faster ore body extraction and less infrastructure requirements.
Traverse Longhole
Utilizes larger rotary drills like the Cubex to drill large diameter blast holes. It is a good drilling type for massive sulfide deposits, large disseminated deposits, or those locations that will be processing high tonnages.
Vertical Crater Retreat
Utilizes larger rotary drills like the Cubex to drill large diameter blast holes. It is a good drilling type for massive sulfide deposits, large disseminated deposits, or those locations that will be processing high tonnages.
Sublevel Caving
Used for near surface large tonnage operations that require little development. Higher initial cost but much lower operational costs during production with multiple mucking points. Typically utilizes top hammer drilling such as the Stopemaster, Solo, or small diameter Cubex drills.
Block Caving
Similar to sublevel caving with high initial costs but much lower operational costs during production. Offers multiple mucking points for large tonnage operations. Utilizes top hammer or small diameter in the hole hammer drills.
Dewatering
Through extensive research and development, Major Drilling has the proven resources, experience, and technical ability to safely and productively execute a variety of underground drainage systems in order to successfully dewater, and thereby reduce ground pore pressures.
