Mine Plan an overview ScienceDirect Topics

Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

Mine Design Relating to Dimensions and underground COAL

Typical continuous miners have wide cutting heads to maximize production (coal being soft enough to not require excessive cutting power). Mining an arch section, particularly in stone requires a narrower head machine to excavate the profile and meet potential power limitations.

Their frame construction, brick clad exterior walls design and layout is typical of coal mine structures of that period. Other structures, such as a garage built in 1932 and the boiler, hoists, pump houses, wash house, coal chutes and storage bins built in 1946 demonstrate the evolution of the site as the coal processing technology developed.

As more easily mined deposits are depleted, the reserves are becoming more limited and less favorable. Deposits of coal or trona that are being longwall mined are deep and are getting deeper. Coal bursts and bumps frequently occur within development entries in longwall mining of deep mines due to high stresses.
