hydraulic mining of coal

Hydraulic Coal Mining Article about Hydraulic Coal ...
In hydraulic coal mining the coal bed is broken down either by means of a high-pressure water jet (5 to 10 meganewtons per sq m), which is formed by monitors, or by means of mechanohydraulic machines (mechanical breakdown of the coal with subsequent washing out by the water). The water is supplied to a stope through pipes from centrifugal pumps.
Hydraulic Mining - an overview ScienceDirect Topics
Hydraulic mining utilizes the force of water sprayed under high pressure to extract coal. Hydraulic mining utilizes continuous miners to mine entries to gain access to production panels. Once a production panel is established, high-pressure water cannons are used to break the coal off the face.

The method of mining coal entails the use of crude petroleum under high pressure together with elevated temperatures in hydraulic fashion to produce a hybrid oil-coal fuel. A powerful stream of oil is aimed at sections of coal strata to disintegrate the coal. The resultant slurry can be recycled for reuse in the mining operation with provisions being made for screening out the larger coal ...

Hydraulic mining Britannica
Hydraulic mining, use of a powerful jet of water to dislodge minerals present in unconsolidated material, including mine tailings, placer deposits, alluvium, laterites (soil rich in iron oxides), and saprolites (soil rich in clay). It has also been applied to consolidated materials from sandstones through coal to hard rock. Hydraulic mining encompasses hydraulicking, sluicing, and educing.

Mar 12, 2020 7. Hydraulic mining. Hydraulic mining uses water to break the ore away and carry it to the surface. In underground mining, one of the most difficult problems to solve is how to get the coal back up to the surface. With hydraulic coal mining, water is pushed at high pressure against the ore’s surface, breaking away the chunks bit by bit.

Mining History: Hydraulic Mining - News From The Diggings
Mar 06, 2017 The Malakoff Diggins is the largest hydraulic mining site in California. Years of hydraulic mining has left an artificial canyon 7,000 feet long, 3,000 feet wide, and 600 feet deep. Early, small scale placer miners referred to the area as Humbug due to many failed attempts to mine the local rivers. Yet, gold was there.
Coal mining - Wikipedia
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...
