i don't know the types of subsurface mining, but i know some facts.surface mining is safer and easier than subsurface mining.You don't have much air underground.It has no or very little advantages compared to surface mining.
There are so many advantages of alluvial soil. Some of the advantages include being fertile, higher water retention capacity as so much more.
Alluvial fan- A fan shaped alluvial deposit formed by a streau where it's velocity is decreased.
underground mining is done when the rocks, minerals of gemstones are too far underground to get out with surface mining some kinds of underground mining are Borehole Mining Drift Mining Hard Rock Mining Shaft Mining Slope Mining

Rubies have historically been mined using traditional methods such as panning in rivers, open-pit mining, and underground mining. In some locations, rubies are also recovered by washing and sorting through alluvial deposits. Modern techniques incorporate machinery and technology to extract rubies more efficiently while minimizing environmental impact.
Diamond mining started in India around the 4th century BC. However, modern industrial diamond mining began in the late 19th century in South Africa after the discovery of diamond deposits in the region.
He was a very successful mining engineer. He may have invented some new methods for handling mining difficulties. (He did not invent the Hoover vacuum.)

Alluvial gold mining left the environment cleared and razed in many places, as large amounts of bushland were cleared for gold mining to take place. This caused some loss of habitat for native animals. In addition, "mullock heaps" (consisiting of the tailings) were left behind to scar the landscape.

something that affects the land by mining is that when you mine you tale minerals out of the earth and the earth needs minerals to survive
Some different types of data mining include clustering, classification, regression, association rule mining, and anomaly detection. Clustering involves grouping similar data points together, while classification involves categorizing data into predefined classes. Regression predicts a continuous value based on input variables, and association rule mining uncovers patterns in data sets. Anomaly detection identifies unusual or outlier data points.
