河北省主要矿区煤层煤中有害元素赋存与分布初探
|
摘要
简述煤中有害元素与环境污染的关系及其对煤炭开采、加工利用的影响,并探讨了煤中有害元素危害的影响因素。从宏观上分析了河北省主要矿区煤层煤中有害元素的含量范围、赋存状态及其物理性质,可初步得出以下结论:其煤中镉、汞、锑等有害元素的含量平均值低于1×10~(-6),煤中砷、铍、铬、硒、钍、铀等元素的含量平均值在1×10~(-6)~10×10~(-6),煤中铜、钴、镍、铅等元素的平均含量在10×10~(-6)~60×10~(-6);煤中氯、氟、磷等元素的平均含量在100×10~(-6)~400×10~(-6);同种痕量有害元素在不同煤样中的变化范围较大,个别矿点的个别有害元素含量较高,但一般不会对环境造成严重污染;省内山西组煤层硫分较低,太原组煤层大多为中高硫煤及高硫煤,不少矿、勘探区为高有机硫煤,因此,大力开展研究有机硫煤的脱硫技术,对合理开采及洁净利用太原组煤层具有重要意义。
The relationship between harmful elements and environmental pollution and how this affected the coal mining,processing and utilization were introduced,and the in fluence factors of harmful elements in coal were discussed too in this paper.In general,the content range,occurrence status and physical properties of coal seam coal in Hebei province were analyzed,the average content of cadmium,mercury and antimony were smaller than 1×10~(-6),the average content of arsenic,beryllium,chromium,selenium,tellurium and uranium were in 1×10~(-6)~10×10~(-6);average content of copper,cobalt,nickel and lead were in 10×10~(-6)~60×10~(-6),the average content of chlorine,fluorine and phosphorus were in 100×10~(-6)~400×10~(-6);The traces of the same species harmful elements changed a lot for different coal sample,the individual mines has high harmful element which will not lead to serious pollution;The Shanxi group of coal has low sulfur content,the Taiyuan group of coal seam are mainly medium-high sulfur coal and high-sulfur coal,and the high organic sulfur coal existed in some of the area,therefore,desulphurization technology of organic sulfur coal should be developed,the reasonable exploitation and clean utilization of Taiyuan group of coal seam has quite important meaning.
