Why coal ash and tailings dam disasters occur | Science

 · On 25 January 2019, the structure damming a pond filled with iron ore mining wastes (tailings) burst at Brumadinho, Brazil (1), causing a massive mudslide that killed at least 232 people. This tailings dam failure was only the most recent in a long list of catastrophic tailings dam accidents (see the first figure) ([ 2 ][1], [ 3 ][2]). Similar accidents also occur at electric power stations ...

Physics of Coal and Mining Processes

 · Improving the safety of mining work while responding to the need for increased coal production, however, is impossible without further development of the physics of mining processes. A relatively new branch of science, it tackles problems that arise during mineral products recovery, particularly safety issues such as rock failures, coal and gas outbursts, and methane explosions.

Processes | Free Full-Text | A Numerical Study of Stress Distribution and Fracture Development above a Protective Coal Seam in Longwall Mining

Coal and gas outbursts are serious safety concerns in the Chinese coal industry. Mining of the upper or lower protective coal seams has been widely used to minimize this problem. This paper presents new findings from longwall mining-induced fractures, stress distribution changes in roof strata, strata movement and gas flow dynamics after the lower protective coal seam is extracted in a deep ...
