Faulting and slope failures in surface coal mining—some
Surface coal mining, as a mechanised operation, has been carried out in this region for about the last 60 years. The earliest workings were on a relatively small scale, and faulting and geologically complex ground was avoided as far as possible; but with time, the introduction of progressively larger excavation plant has led to ever larger and ...

A novel method for identification of disturbance from surface coal …
Surface mining can recover a higher percentage of coal (over 90 %) than underground mining, but the choice of mining type is usually limited by the geological characteristics of the proposed mine, the location of the coal seams, and the equipment available at the time the mine begins operations (Colaizzi, 2004, Ben-Awuah et al., 2016).

Coal Mining Methods
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.

The Thin Coal Seam (TCS) Mining Technology for Open Pit
Coal seam that is thinner than a certain value is defined as thin coal seams (TCS). It commonly occurs in China as it covers 84.2% of the mining area. This situation is even severe in China's large surface coal mines, in which TCS accounts for 10–50% of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of …
