Strip mining became the preferred method in southeastern Kansas in the 1930s, although underground mining continued there until 1960 and in Osage County until 1964. During strip mining operations, overlying soil and rock, called overburden, is stripped away using power shovels to expose coal beds too thin to be mined underground.

Mining engineer and English émigré Joseph Squire revolutionized coal-mining operations upon his arrival in central Alabama in 1859. Settling in Montevallo, he worked at different times for both Browne and the ACMC. He used practical experience, exploration, testing, charting, and mapping to identify seams and to solve various extraction problems.
In the coal mining cycle, three basic steps related to soil resources are distinguished: 1. Premining, which includes the removal (stripping) of vegetation, the removal of soil removal, and its transportation and storage in preservation banks, 2. Mining that includes the excavation of layers of rock material and extraction of coal itself, and 3.
