Underground mining (hard rock) Wikipedia

One of the most important aspects of underground hard rock mining is ventilation.Ventilation is the primary method of clearing hazardous gases and/or dust which are created from drilling and blasting activity (e.g., silica dust, NOx), diesel equipment (e.g., diesel particulate, carbon monoxide), or to protect against gases that are naturally emanating from the rock (e.g., radon gas).

Ground Control RockEng

Ground control plays a significant role in keeping mines safer and more productive. Ground Control – The main purpose of ground control in a mining context is to ensure that all excavations made through rock and soil are kept safe and stable at all times (this practice can also sometimes be referred to by miners as slope management or strata control).
