Major Mines Projects - Mining Intelligence and News

Mechanised cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. As the name of the method implies, successive cutting of the ore into horizontal slices is carried out starting from the bottom of the stope and progressing upwards towards the surface. This horizontal slicing leaves a void that is backfilled with waste ...

mechanised coal mining doc - help4helpngo

The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

A River with Rights: Community Response to Illegal

The small-scale mechanised mining gold rush arrived in Paimadó, Rio Quito, with technical diggers in 1999 (Tiempo, 2009). Approximately ten years later, in 2009, a government inter-agency Commission revealed that this small-scale mechanised mining, numbered 24 mechanised platforms, each of them extracting on average 300 grams of gold per 20-hour day. They had dumped in the river: four tons of ...
