Study on Gas Emission Prediction of Steeply Inclined Coal Seam Applied Horizontal Slice Mining

Abstract: Calculation of emission quantities from different gas emission sources is important to predict gas emission quantity on the horizontally layered working face of a steep seam. However, existing gas emission prediction model has many problems, such as complicated calculation links, poor accuracy and non-applicability to the steep seam. In this study, a model applicable to predict gas emission from horizontal mining layer of steep seam was constructed based on the different-source prediction method. This model wa… Show more

“…The coal reserves in eastern China are on the decrease, and the mining depth and difficulty in mining there are becoming severe. Because they feature simple structures, rich reserves [1], and shallow burial depths, the western coal fields have become key mining areas in China [2]. Compared with the strata in the east, the strata in the western mining areas feature poor cementation, low strength, and easy disintegration.…”

“…For example, fire accidents resulting from the outburst of coal and gas must be eliminated urgently [5][6]. Gas, as a clean energy source, has minimal environmental pollution during utilization, and its application potential can be widely tapped [7,8]. This feature makes gas mining a focus in the field of coal mines.…”
