在深入研究地气测量技术和江西省萍乐坳陷西段地质特征基础上,通过对已知煤层隐伏区—丰城煤矿区进行野外地质调查,在隐伏煤层区与无煤区采集土壤样品,运用酸解烃法测量土壤中甲烷等烃类气体含量。其成果显示,隐伏煤层区在地表土壤中呈现明显的甲烷正异常。对未知含煤区—洪塘普查区进行地气测量工作,预测隐伏煤层区,并进行钻探验证,其成果与预测一致。
Based on the in-depth study of the geo-gas measurement technology and the geologic features of the west section of Pingle depression in Jiangxi Province, the field geological survey was conducted in the concealed coal seam area of Fengcheng, a known coal seam. Soil samples were collected from the concealed coal seam area and the coal- Determination of Methane and Other Hydrocarbons in Soil by Acid Hydrolysis. The results show that the hidden coal seam area shows obvious positive anomalies of methane in the surface soil. Geological survey of unknown coal-bearing area - Hongtang census area, prediction of hidden coal seam area, and drilling verification, the results consistent with the forecast.
