Big data cleaning modeling of operation status of coal mine fully—mechanized coal mining equipment

Gong-kuang zidonghua, 2018
In view of problems of large amount of data and noise and missing values existed in data of operation status of coal mine fully—mechanized coal mining equipment, a big data cleaning model of operation status of coal mine fully—mechanized coal mining equipment based on MapReduce was established. The model is composed of dual MapReduce.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Moving in Cycles: Explaining the Failure of Militarization to Address Illegal Mining in Ghana

Politics &Policy, Volume 54, Issue 4, August 2026.
ABSTRACT Mining contributes to Ghana's economic growth but also imposes significant social costs—land dispossession and unemployment—which have fueled the rise of illegal mining (galamsey). Galamsey, which intensified during the commodity boom of the 2010s, provides livelihoods while simultaneously worsening environmental degradation and social ...
