Priargunsky Industrial Mining and Chemical Union has been exploiting the deposits of Streltsovskoe ore field during 45 years. For this period, there were developed the most rich and powerful ore bodies. Basically, the development process was carried out with application of the «Horizontal layers with solid stowing» system and «top-down» method. This article considers the problem of reduction of first workings during the application of the «Horizontal layers with solid stowing» system. Authors of this article have proposed the development method of low-powerful ore bodies, when during the application of the development system «Horizontal layers», the stope reserves with 60 m height and 3 m layer height, are developed from 7....8 layer orts.
