  • Reasonable coal pillar design and remote control

    4.2. Mining design. The HTM working face is located at the northwestern boundary of the coal mine, which is seated in the 2# coal seam with 390 m along the strike direction and 60 m along the dip direction. The mining design is shown in figure 12. This area cannot be exploited by the open-pit mining (PDF) Surface Mine Design ResearchGate,Auger mining is a surface mining techniq ue used to recover additional coal from a seam located behind a highwall produced either by stripping or open-pit mining.

  • Best Practices For Dust Control In Coal Mining

    2012-8-30 · many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers’ pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and/or fatal lung,
