In mining, a bogger refers to a type of machinery used for removing broken rock, ore, or waste material after blasting. It is also known as a load-haul-dump (LHD) machine. Boggers are specifically designed for underground mining operations, where space can be restricted.

　　Features of an Underground Bogger:

　　1. Compact and Low Profile:

　　- Designed to operate in narrow and low-clearance underground tunnels.

　　- The low-profile design helps it navigate tight spaces.

　　2. Bucket Capacity:

　　- Equipped with a front-loading bucket that can range from 0.5 m? to 10 m? or more, depending on the machine size.

　　- Used for scooping, lifting, and dumping ore or waste material.

　　3. Power Options:

　　- Diesel-powered boggers: Common in remote or deep mining operations.

　　- Electric-powered boggers: Increasingly popular for their lower emissions and reduced operating costs, suitable for mines aiming to reduce environmental impact.

　　4. Articulated Steering:

　　- Flexible joints allow the bogger to make sharp turns in narrow passages.

　　5. Durable and Rugged Construction:

　　- Built to withstand harsh underground conditions like dust, moisture, and rough terrain.

　　6. Safety Features:

　　- Enclosed operator cabins with protective systems.

　　- Advanced braking and monitoring systems.

　　Primary Uses:

　　1. Clearing blasted rock or ore.

　　2. Loading material onto haulage vehicles or conveyor systems.

　　3. Assisting in the development of underground tunnels by moving debris.

　　The term "bogger" is widely used in mining regions such as Australia and Canada.
