Within the land plot occupied by a mine, there may be one or more lifting shafts, and each of them serves a certain well-defined part of the seam or suite of mineral deposits. The area of such part of the seam or suite is called a mine field. Like any area, a mine field measured in square units, that is, determined by the product of two linear quantities. Unfortunately, our practicing engineers share their experience very sparingly, and there is no data on this issue in the specialized literature. This article discusses various formula methods for determining the size of a mine field.
