Novel approach for extinguishing large-scale coal fires ...

Coal fires are a serious threat to the workers' security and safe production in open pit mines. The coal fire source is hidden and innumerable, and the large-area cavity is prevalent in the coal seam after the coal burned, causing the conventional extinguishment technology difficult to work. Foams are considered as an efficient means of fire extinguishment in these large-scale workplaces. A ...

What Is Open-Pit Mining? (with picture) - wiseGEEK

21/02/2021· The process of open-pit mining is precipitated by the analysis of the area in order to determine the presence of the desired material that may be coal or ore. If it is determined that the desired materials are present in the area, the next step would be to calculate the stripping ratio of the mining process, meaning that even though ore, coal or another desired material may be present, the ...

History of coal mining - Wikipedia

Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits.As well as drift mines, small scale shaft mining was used. This took the form of a bell pit, the extraction working outward from a central shaft, or a technique called room and pillar in which 'rooms' of coal were extracted with ...

Opencast Mining - an overview | ScienceDirect Topics

The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste ...
