Abstract
The influence of various factors on the condition of the edge zone of the coal seam ahead of the face during the development of flat seams is assessed. All the variety of factors can be divided into mining-geological and mining-technical. Of mining-geological factors, the greatest influence on the coal deformation in the peripheral zone have such factors as power, depth of development, dip angle, presence of interlayers, of mining-technical - face length, speed of its movement, development system, type and power characteristics of the support, method of rock pressure control.
