Coal mining - Underground mining Britannica

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face or section haulage, which transfers the coal from the active working faces; intermediate or panel haulage, which transfers the coal onto the primary or main haulage; and the main haulage system, which removes the coal from the mine.

The Mining Process Introduction underground COAL

Such roadways need to be stable for extended periods (some for the whole life of the mine) and in most mines this means supports need to be installed to reinforce the roof and in many mines, the sides (referred to as "ribs") and sometimes even the floor strata. This support work is an expensive process, primarily due to the extent of manual handling and operation involved.

Selection of an appropriate fan for an underground

2015-4-1  To ensure a safe and productive environment in an underground coal mine, a good ventilation system is mandatory. A good ventilation system should ensure that the regulatory requirements are met throughout the mine while also providing miners with sufficient fresh air and keeping operating costs to a minimum (Sasmito et al., 2013). Adequate airflow in underground mines is necessary to create a safe environment for mine

2021-5-9  Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In open-pit coal mining, a pit is dug in an area and this pit becomes the open-pit mine, sometimes called a quarry.Open-pit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great.

Escape-Route Planning of Underground Coal Mine

When a mine disaster occurs, to lessen disaster losses and improve survival chances of the trapped miners, good escape routes need to be found and used. Based on the improved ant algorithm, we proposed a new escape-route planning method of underground mines. At first, six factors which influence escape difficulty are evaluated and a weight calculation model is built to form a weighted graph of ...
