Disadvantages of subsurface mining

Underround mining method of mining involves excavating ore, mineral deposits, seams, or ore bodies underground and then extracting these mined resources to the surface. Underground mining is generally more suitable for mineral resources located deeper below the surface than open-pit mining.
This mining method involves the following main steps:
Prospecting and prospecting: Prospecting and prospecting work is usually required before underground mining can begin. This includes geological exploration to understand the nature, size and distribution of underground ore bodies.
Construction of openings and passages: In order to access the underground for mining, openings or passages, often called mine shafts, need to be constructed on the surface. This can be achieved by means of vertical shafts, inclined shafts or horizontal holes.
Mining: Once underground, miners use a variety of tools and equipment, such as drills, blasting devices, and boring machines, to dig and mine the ore. This may involve creating chambers or passages within the ore body so that the ore can be extracted.
Support and stabilization: Due to the instability of the underground environment, support and stabilization work must be carried out to prevent underground caverns from collapsing. This can be achieved through the use of support structures, grouting and other methods.
Transportation and Extraction: After mining, the ore needs to be transported to the surface. This can be accomplished using lifting systems, conveyor belts, or other transportation equipment.
Processing: Ores mined underground often require further processing on the surface to extract valuable minerals. This may include steps such as crushing, grinding, and flotation of ore.
