6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

The decision to use underground or surface mining techniques is dependent on the proximity of the ore body to the surface. Lead-zinc underground mining techniques use shafts, drifts, and adits to access the ore body. The most common underground mining method to remove the ore is room- and-pillar. (U.S. DOI, Bureau of Mines, 1984; 198Sa).

(lead/zinc) ground along a proposed interstate route near Joplin, Missouri. A total of 6 000 m of high-resolution reflection seismic data, 3 000 m of ground-penetrating radar (GPR) data, and nine seismic check shots were acquired. The geophysical survey was successful.
Mining. Lisheen is being mined using room and pillar, and drift and fill techniques. Blast hole stopping is adopted for areas that appear to be thicker. To access the mine, a 1.5km long decline was descended. Holes are bored in the orebody using underground drilling rigs, charged with explosives and blasted.
The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits. However, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.
