Coal bots in every f2p world in the mining spot next to Father
But bot farms need to be dealt with as soon as they are found or it could cause economic issues. This coal bot farm for example. 29 F2P US worlds, 4 bots per world all mining coal, that's just over 400K gp for every single inventory of botted coal. Why would anyone mine coal when there's miscellania. Cause it's F2P bots.However, frequent safety accidents during coal mining hindered the healthy development of coal mining enterprises.

Beginner's Guide to Coal Mining An Underground Miner
Civilizations developed the technology for fossil fuel mining technology over thousands of years. In ancient times, burning coal provided heat for baths, forges, and buildings. Beginning in the 18th century, the Industrial Revolution vastly increased the demand for cheap energy sources. Factories, transportation, and power plants came to In recent years, concern has been increasing regarding the carbon emissions generated by mining activities. China is an extremely large coal producer (3695 Mt/2015) and consumer (3698 Mt/2015), and Shanxi Province (i.e., a major coal-producing province in China) is a crucial element in China’s energy conservation and emission Environmental impact of mining-associated carbon emissions and

Coal mining Underground, Surface, & Drilling Britannica
Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner’s progress.According to the numerical simulation results and Fig. 4, the main escape routes can be determined for disasters that occur at the coal mining working face and the tunneling working face, as wellStudy on emergency escape route planning under fire accidents
