摘要
针对当前矿井生产过程中出现一氧化碳气体,为了对一氧化碳产生来源进行有效分析,在生辉煤业20100综放面进行试验研究,根据现场试验结果推断煤层不存在原生CO气体;施工钻孔密封之后测定出CO气体,判定其源头是施工过程破煤导致的。
In view of the problem of CO gas in the current mine production process,in order to effectively analyze the source of CO gas,an experimental study was carried out in the 20100 fully mechanized caving face of Shenghui Coal Industry.According to the field test results,it is inferred that there is no primary CO gas in the coal seam;CO gas was measured after the construction borehole was sealed,and it was determined that its source was caused by coal breaking during construction.
