2020-8-25 1. Underground Mining Methods 1.1. Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are

2021-1-27 What is a Process Flow Diagram (PFD)? Process Flow Diagram (PFD) is a commonly used chart in chemical engineering and process engineering demonstrating the ongoing production flow of chemicals and other types of equipment involved. The concept of the process flow diagram was first pointed out by Frank Gilbreth, an American industrial engineer, in the 1920s.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale 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.

Ore and waste rock are mined by excavators loading onto trucks. In the open pit the trucks take their loads to the primary crushers or to stockpiles. In the underground mine the ore is taken to stockpiles at the processing plant, while waste rock is stockpiled for reuse as backfill once mined areas are completed.
