摘要
因国家及煤炭行业尚未出台风氧化煤判定标准及规范,各地区对风氧化煤的判定一般根据本地区经验进行,但总体上一般均以煤质化验指标中的腐植酸含量作为煤层是否风氧化的判定标准。但在某矿风氧化带补充勘探中发现腐植酸不能单独作为煤层风氧化的标志,通过对该工程资料的总结分析,发现氧含量是影响煤层风氧化的主要因素,腐植酸含量为次要因素,其他诸如发热量、水分、灰分、挥发份等为辅助因素,煤层风氧化的判定往往是几方面因素综合所得。
Because the country and the coal industry have not yet issued the judgment standards and norms of the wind oxidized coal,the judgment of the wind oxidized coal in each region is generally based on the experience of the region,but generally,the humic acid content in the coal quality test index is taken as the judgment standard of whether the coal seam is wind oxidized or not.However,it is found that humic acid can not be used as a sign of coal seam wind oxidation in the supplementary exploration of a mine wind oxidation zone.Through the summary and analysis of the engineering data,it is found that oxygen content is the main factor affecting coal seam wind oxidation,humic acid content is the secondary factor,and other auxiliary factors such as calorific value,water content,ash content and volatile content are the auxiliary factors.The judgment of coal seam wind oxidation is often the comprehensive result of several factors.
