摘要:
为了探究煤矿硫化氢异常富集主控因素,以陕西彬长小庄矿4#煤层为研究对象,通过分析煤层热演化温度、吸附特性、孔隙特征、全硫含量以及还原性指数等影响煤体自身物化性质的主控因素,并运用灰色系统理论构建广义灰色关联度评价模型,以定量的方式确定各因素的广义关联度大小。结果表明:当煤层硫化氢浓度由08×10-6升高至6×10-6时,对应热演化温度、吸附常数、BET比面积、全硫含量以及还原性指数变化范围分别为:96~113 ℃,288~362,0412 5 ~0986 4 m2·g-1,021%~088%,31~85,主控因素综合关联度排序为:还原性指数>吸附常数>全硫含量>热演化温度>BET比表面积。
Abstract:
In order to explore the main controlling factors for abnormal enrichment of hydrogen sulfide in coal mine, taking the 4# coal seam of Binchang Xiaozhuang coal mine in Shaanxi as the research object, the main controlling factors affecting the physical and chemical properties of coal body were analyzed, including the thermal evolution temperature, adsorption characteristics, pore characteristics, total sulfur content and reducibility index of coal seam. An evaluation model of generalized grey relational degree was established by using the grey system theory, and the generalized relational degree of each factor was determined quantitatively. The results showed that the variation range of thermal evolution temperature, adsorption constant, BET specific surface area, total sulfur content and reducibility index were 96-113℃, 28.8-36.2, 0412 5-0986 4 m2·g-1, 021%-088% and 3.1-8.5 respectively when the concentration of hydrogen sulfide in coal seam increased from 08×10-6 to 6×10-6. The sequence of comprehensive relational degree for the main controlling factors was: reducibility index > adsorption constant > total sulfur content > thermal evolution temperature > BET specific surface area.
