Blast Hole Open Stoping

Manufacturing Term

Blast Hole Open Stoping (BHOS) is a mining method that involves drilling holes into a rock mass and then blasting the rock to create voids or stopes. The stopes are filled with waste rock or backfill material to support the surrounding rock and provide a safe working environment for miners.

BHOS is commonly used in underground hard rock mining operations where the orebody is relatively flat and thick. The method is particularly suitable for large, low-grade orebodies that require high production rates and low mining costs.

The process of BHOS involves drilling blast holes, which are usually 10-12 centimeters in diameter, into the rock mass at regular intervals. Explosives are then placed into the holes and detonated, which breaks up the rock and creates the stope.

Once the stope is created, waste rock or backfill is placed into the void to provide support for the surrounding rock. The waste rock is usually taken from other areas of the mine and can be used to fill the stope as it is created, which reduces the amount of waste rock that needs to be transported to the surface.

BHOS is widely used in the mining industry, but it is not commonly used in the manufacturing industry. The method is primarily used to extract natural resources, such as minerals, metals, and coal, from the earth. However, some manufacturing industries may use similar techniques, such as blasting or drilling, to remove or shape materials during the production process.
