A twin boom drill jumbo is a type of underground drilling equipment equipped with two independent drilling arms (booms). It provides greater flexibility, efficiency, and coverage compared to single-boom models. Twin boom drill jumbos are commonly used in medium to large-scale tunnel excavation, mining operations, and hydroelectric or transportation infrastructure projects.

   1、Functions of the Twin Boom Drill Jumbo

   The primary function is drilling holes in rock for blasting operations. Each boom carries a rock drill and can operate independently. This allows the operator to drill multiple holes simultaneously or position the drills at different angles for higher efficiency.

   2、Applications of the Twin Boom Drill Jumbo

  ① Tunnel Construction

   Widely used in road tunnels, railway tunnels, subway systems, and hydropower tunnels.

   Its wide drilling coverage ensures rapid progress in large tunnel cross-sections.

   ② Mining Operations

   Suitable for underground hard rock mining where drilling and blasting are the main excavation methods.

   Used for developing mine drives, crosscuts, and production headings.

  ③ Hydropower and Water Conservancy Projects

   Applied in the construction of diversion tunnels, underground caverns, and other hydraulic engineering structures.

   A twin boom drill jumbo is a drilling machine with two booms, designed to make underground excavation faster and more efficient by drilling multiple blast holes at the same time. It is dual-boom configuration provides high efficiency, wide coverage, and precision, making it indispensable for large-scale underground excavation projects.
