Once it reaches the seam, the coal is then mined laterally along the seam either side of the shaft, creating the bell shape.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Techniques were developed that allowed mining companies to determine the gassiness of coalbeds. Armed with this new technology, USBM researchers conducted a number of geological studies that identified the gassiness of most major coal basins. This information was used by most coal mining companies as a planning tool for methane control systems.
