The experience of works on dismantling powered coal face systems at the mines of Kuzbass and the USA is discussed. The factors influencing the duration of dismantling of powered complexes are determined. Based on the experience of dismantling works, a scheme with a polymer mesh canopies and pilot sections of powered mining complexes with the formation of a chamber by a face has become widespread. To reduce the time for dismantling works, a technology with the use of dismantling shield (two “pilot” sections connected by an E-frame), which allows the minimum possible time for reassembly of the coal face system equipment to be achieved.
