【摘要】：為探討巖-煤蝕變過程中礦物變化特征,通過工業(yè)分析、LTA-XRD等技術(shù)手段測試了淮北臥龍湖煤礦8煤層巖漿侵入體、巖-煤蝕變帶及蝕變煤中灰分、揮發(fā)分、水分、各形態(tài)硫及礦物質(zhì)含量。結(jié)果表明,巖漿侵入導致煤中灰分升高,黃鐵礦硫增加,有機硫減少;研究區(qū)煤中主要礦物成分為石英(8.3%)、黃鐵礦(0.1%)、伊利石(60.9%)、高嶺石(20.2%)、方解石(3.6%)、菱鐵礦(0.2%)和鐵白云石(6.9%);石英、鐵白云石及黃鐵礦含量由侵入體→蝕變煤→未蝕變煤逐漸降低;蝕變煤中黃鐵礦、石英及碳酸鹽礦物主要來源于巖漿熱液。巖漿熱液對煤層的蝕變,導致煤質(zhì)及煤中礦物種類、含量及賦存狀態(tài)發(fā)生了顯著變化,部分礦物在熱液作用下蝕變形成新礦物。
[Abstract]:In order to study the characteristics of mineral change in the process of rock-coal alteration, the magmatic intrusion, rock-coal alteration zone and the ash, volatile and moisture in the 8 coal seam of Wolong Lake Coal Mine in Huaibei were measured by means of industrial analysis and LTA-XRD. Sulfur and mineral contents in various forms. The results showed that the ash content in coal increased, pyrite sulfur increased and organic sulfur decreased due to magmatic intrusion. The main mineral components of coal in the study area were quartz 8.3g, pyrite 0.1, Illite 60.9, kaolinite 20.20.20. 2X, calcite 3.6m, siderite 0.20.22) and iron dolomite 6.9m. The contents of ferrite dolomite and pyrite decrease gradually from the intrusive altered coal and the pyrite quartz and carbonate minerals in the altered coal are mainly derived from magmatic hydrothermal solution. The alteration of coal seam by magmatic hydrothermal solution has resulted in significant changes in the types, contents and occurrence of minerals in coal and some minerals have been altered into new minerals under the action of hydrothermal solution.
