| H2S is a highly toxic, colorless gas with a rotten egg smell. Abnormal of H2S incoal mine gas anomalies (over coal mine production safety requirements6.6ppm)seriously affecting the lives and safety of mine workers and level production.Thispaper studies H2S abnormal in Fukang mine coal, the use of coal exploration andmine development information through comparative analysis of normal coal miningcoal H2S anomalies in geological formations, coal structure, coal, adsorption,hydrogeology and burnt differences with other aspects. Author believes mine reversefaults and shear zones developed extrusion fault, intense tectonic coal developedregions, there is a stable impermeable layer of coal or coal seam water andgroundwater weak contact or no contact areas, burnt rocks formed H2S dissolved inwater when coal and rock with groundwater migration is easy to cause seam gasadsorption H2S exception; H2S adsorption of coal and rock H2S content wasassociated with coal, Coal H2S content and moisture content (Mad), ash yield (Ad) wasnegatively correlated trend with total sulfur content (St.d), volatile matter yield (Vdaf)was positively correlated with trends and gas CH4, N2and CO2was negativelycorrelated with increasing depth of coal tend to decrease. |
