It is the same technique used for hard rocks. By using this method, oil shale, salt, phosphate, potash, coal, and bedded uranium ores are excavated. It can recover about 50% of the ore. Shortwall Mining. Short-wall mining is a method that is generally used for coal mining.

  • 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. (PDF) Mining methods underground mining mayra garcia,Mining methods underground mining. Mayra Garcia. Download PDF.

  • Mining Wikipedia

    Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.Gypsum Minerals Education Coalition,The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly associated with rock salt and sulfur deposits. It is processed and used as prefabricated wallboard or as industrial or building plaster, used in cement manufacture, agriculture and other uses. Relation to Mining. IMAR 7 th Edition.

  • Mining techniques for companies, surface, underground

    Mining Techniques is divided into two types: surface mining and underground mining.Mining targets are divided into two categories of materials: placer deposits and lode deposits. If a mineral is stable chemically and is resistant physically, it can be eroded from its primary hard-rock occurrence and transported to river channels, deltas or other sedimentary environments where it can be,
