Abstract

Protective seam mining is a major and critical regional measure to prevent coal and gas outbursts (CGO) in coal mines. In this study, a novel method for selecting protective seam against coal and gas outburst was studied on the basis of gas geology and rock strata control theories and principles for protective seam mining and relevant regulations, which is that theories of gas geology were used to assess the outburst risk inherent in different seams of this mine, and then make preliminary selection of protective seams, and the technical feasibility of the proposed selection method was then analyzed using the theories and principles for protective seam mining and relevant regulations. The case application study results show that the extraction of the upper protective seam (UPS) caused significant decreases in the predicative indicators of outburst risk in the outburst-prone seam and thereby prevented CGO, and the novel method can provide a theoretical basis for selecting protective seam against CGO.
