Coal mining - Underground mining | Britannica

Coal mining - Coal mining - Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...

The Evolution of Intelligent Coal Pillar Design: 1981-2006

pillar design all the way back to Coulomb in 1773. During the ensuing century, a variety of researchers tested rock specimens of a variety of sizes and shapes. However, it was not until 1911 that Bunting (1991) proposed the first true pillar design method for coal mines. Bunting described the necessity for pillar design this way:

Floor design in underground coal mines - NASA/ADS

Floor failure and excessive heave in underground coal mines can jeopardize the stability of the whole structure, including the roof and pillars, due to differential settlements and redistribution of stress concentrations. Besides, floor failure is detrimental to haulageway operation and can lead to unacceptable conditions of high deformation. Thus, the design of any underground opening must ...

Analysis of coal pillar stability (ACPS): A new generation ...

The coal mine roof rating (CMRR) rock mass classification was developed so that geologic factors could be quantified and integrated into the longwall pillar design process. Ultimately, a large database of case histories was collected during visits to longwall mines throughout the US, and modern multi-variate statistical techniques were used for the first time to analyze the data [3] .
