Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.
Here is a list of all Factors Affecting Filtration Rates and Cake Moistures in plants or laboratory de-watering systems and processes. Particle Size of Solids Generally the large the particle size, the higher the filtration rate in Kg/m2/h and the lower the cake moisture. However, the validity of the last statement depends on other factors, e.g. distribution specific gravity of solids, absence ...
The equipment selection process for an underground mine design plan has an extremely wide scope as there are a myriad of parameters to consider when incorporating mobile and stationary equipment in hard or soft rock mining applications. This article primarily focuses on the initial selection of mobile equipment in hard rock mining operations.
