Underground Mining (sage ability)

Underground Mining is an authority-status sage ability in the study of Geology, encompassing a comprehensive expertise in subterranean environments. This ability represents a mastery of the techniques and practices associated with mining, including the excavation of both hard and soft materials, the engineering of safe passageways and the identification of valuable resources within the earth. Characters with this skill possess a deep understanding of the unique challenges and hazards of working underground, allowing them to approach such endeavours with a blend of scientific insight and practical know-how.

Understanding Subterranean Structures

Characters with this ability can read the characteristics of rock and soil formations with precision, interpreting their layers and variations to anticipate the natural forces at play. This includes recognizing fault lines, areas of potential collapse or the presence of underground water. Their expertise extends to identifying ancient or natural caverns and tunnels, discerning their structural integrity and estimating the time elapsed since their creation. Such insights allow characters to determine whether a passage is safe to traverse or requires reinforcement before further use.

Additionally, this understanding includes a sensory awareness of air quality underground, detecting noxious gases, oxygen depletion or the presence of airflow that might indicate nearby openings or surface access. These subtle environmental cues are vital for survival and success in subterranean exploration.

Initiating a Mine

When tasked with creating a mine at a chosen site, characters with this ability understand the fundamental methods for excavating shafts, adits or inclines. These efforts often begin with the clearing of topsoil and the cutting of an entrance into the bedrock.

The miner's expertise includes ensuring the safety of these initial excavations. Early reinforcements are constructed using materials at hand, such as timber beams or stacked stone, to support the weight of the overlying earth. Where water is a concern, drainage channels or sumps are dug to manage seepage, ensuring that the working areas remain dry and stable. Simple pulley systems or winches are often employed to assist in the removal of waste material.

Ventilation is a critical concern, particularly in deeper mines where air circulation is poor. Miners use methods such as opening secondary shafts, building vertical airways or using basic bellows to keep the air fresh and breathable. The miner also knows how to detect and respond to hazards such as unexpected flooding, gas accumulation or shifting rock.

Extraction Process

The methods of extraction reflect the technology of the era. Characters with this ability are skilled in the use of hand tools such as pickaxes, hammers, chisels and shovels to break and remove material. Where particularly hard rock is encountered, miners may use techniques like “fire-setting,” a method of heating rock with fire and then cooling it rapidly with water to cause fracturing.

Transporting material from underground to the surface is accomplished through simple means such as hand-barrows, wooden sledges or rope-and-pulley systems. The miner understands how to organize the workflow to minimize bottlenecks and ensure efficiency in the removal of waste and extraction of valuable materials.
