铁新井田太原组煤层硫化氢成因分析
|
摘要
为研究铁新矿太原组煤系地层硫化氢成因,探讨从井田地质特征和地层沉积历史方面进行分析,根据地层沉积环境及典型矿物质研究硫化氢成因.铁新井田位于山西中隆起、沁水拗陷霍西向斜北部,灵石-富家滩复背斜北西翼,井田地层包括奥陶系、石炭系、上第三系上新统和第四系,海陆交替沉积.主采煤层为石炭系上统太原组,顶板海相灰岩沉积.10号煤富含黄铁矿结核,成煤过程中在硫酸盐还原菌作用下生成大量硫化氢.煤层底板奥陶系中统峰峰组富含石膏矿,裂隙水发育,地层沉积期硫酸盐热化学还原生成大量硫化氢,通过地层岩体裂隙侵入煤系地层中,使煤层硫化氢含量增大.研究表明:铁新矿太原组煤层硫化氢成因主要为微生物硫酸盐还原作用和硫酸盐热化学还原作用.
In order to study the causes of coal seam hydrogen sulfide in Tiexin mine field, mine geological characteristics and formation sedimentary history especially the typical minerals were studied. Tiexin mine located in Shanxi uplift, north of Huoxi syncline in Qinshui depression, Lingshi- fujiatan anticlinorium north west wing. The field strata including ordovician, carboniferous, upper pliocene of tertiary and quaternary, land and sea alternate deposition. Main coal seam is carboniferous Taiyuan formation, and deposited marine limestone on roof. 10 coal is riched in pyrite tuberculosis, so a large amount of hydrogen sulfide might generated in the role of sulfate-reducing bacteria during coal-forming process. Fengfeng group ordovician rich in gypsum mine, fissure water development, a lot of hydrogen sulfide could generate from thermochemical sulfate reduction. The gas through strata fissure invade coal formations, resulted in hydrogen sulfide content rise in coal seam. The main cause of hydrogen sulfide in Tiexin mine Taiyuan group were microbial sulfate reduction and thermochemical sulfate reduction.
