Underground mining (soft rock) - Wikipedia

Underground soft rock mining is a group of underground mining techniques used to extract coal, oil shale, potash and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic rocks (see Underground mining (hard rock)). Underground mining techniques also differ greatly from those of surface mining.

How Is Sandstone Mined? Career Trend

Aug 26, 2019  Sandstone is sedimentary rock composed of grains of sand that settles in one place, forms layers and combines with minerals. Sedimentary rock occurs from millions of years of sand settling on the bottoms of rivers, oceans and lakes. Each layer is pressed into the last until it turns to rock. Sandstone is the most common sedimentary rock.

Glossary of Mining Terms - Rock, Mineral Fossil Collections

Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

5. Rock Excavation Tools Drilling and Excavation ...

Thermal spalling drills such as jet-piercing and forced-flame drills heat rocks to 370 to 540°C (700 to 1000°F) to create thermal stresses that spall the rock ().These devices have limited application because most rocks will not thermally spall (Maurer, 1968, 1980). Melting and vaporization drills utilize high-temperature devices such as lasers or electron beams to melt and vaporize rock ().

How Underground Mining Works HowStuffWorks

Coal deposits, for instance, live in relatively soft sedimentary rock. Gold deposits live in igneous or metamorphic rock, which is relatively hard, as do diamonds, copper, silver, nickel and zinc [source: Great Mining]. Even within the hard-rock category, design and extraction methods vary, but almost all revolve around a few basic techniques:

Common Sedimentary Minerals - University of Pittsburgh

Thus, of the eight common igneous minerals, only quartz, K-feldspar, and muscovite are commonly seen in sedimentary rocks. These minerals are joined in sedimentary rocks by clay minerals, calcite, dolomite, gypsum, and halite. The clay minerals form during mineral weathering. The other four minerals are salts that precipitate as water evaporates.
