Agnico Eagle Kittilä gold mine in Finland commissioned such a unit – reported to be one of the first mine in the world to do so. One of the drivers in their approach was a 30% higher annual production target. Kittilä mine uses the sub-level stoping mining method. The average stope height is 25m but can be as high as 40m.
Longhole Stoping is a popular large scale underground mining method for metalliferous mine known for its ability to simplify stope sequencing. It encompasses advantage of Faster Stope Production ...

Independent rotation drifter longhole drilling has been practised over many years utilising relatively small diameter blast holes (±50 mm). Accuracy constraints limited the lengths to shorter holes, i.e. generally around 40 m. Longer holes can be drilled but accuracy is not guaranteed. Drilling accuracy is partially determined by
Long-hole open stoping is used in both hard rock and soft rock mining operations and is ideal for mining steeply dipping ore bodies, where it is more challenging to drill parallel drifts and cross cuts. How Long Hole Open Stoping provides advantages over other mining methods. Long-hole open stoping is becoming more popular for a number of reasons:
Longhole blast hole drilling' techniques are not new to the mining industry. Appropriate mechanization and improvement of the techniques and application has evolved from the industry requirements.
