Kaivannaisalalla

Kaivannaisalalla, also known as "mining on the edge," refers to a mining technique used in the late 19th and early 20th centuries, particularly in the United States. This method involved mining coal or other minerals from the edge of a hill or cliff, rather than from the bottom of a valley. The miners would dig a series of tunnels and shafts along the edge of the hill, allowing them to extract the mineral deposits without the need for extensive underground workings.

The kaivannaisalalla technique was particularly common in the Appalachian region of the United States, where coal deposits were often found along the edges of hills. This method allowed miners to access the coal more easily and quickly than traditional underground mining techniques. However, it also presented significant safety risks, as the miners were exposed to the elements and had to work in steep, unstable terrain.

Despite these risks, kaivannaisalalla mining remained a popular method for many years. It was often used to extract coal from deposits that were too shallow or too steep for traditional underground mining techniques. However, as mining technology advanced and safety regulations became more stringent, kaivannaisalalla mining began to decline in popularity. Today, it is largely a thing of the past, but it remains an important part of the history of American mining.
