摘要
为了揭示煤矿井下封闭采空区内细菌对CO消失的影响机理,自主研发了细菌对CO消失影响规律的实验装置,通过对比实验,分析了空气灭菌前后、煤样灭菌前后以及灭菌水分等条件下密闭空间内煤样中CO、CO_2气体变化规律。实验结果表明细菌的存在会对CO的消失起到一定的作用,研究结果及思路可对封闭采空区进行精准预判提供参考依据。
In order to reveal the influence mechanism of bacteria on CO disappearance in sealed goaf, an experimental device of bacteria effecting on CO has been developed autonomously. By contrast experiment, the change law of CO and CO2 of coal samples are analyzed in sealed space under the condition of air sterilization before and after, coal samples sterilization before and after and water sterilization. The results show that the presence of bacteria plays a role in the disappearance of CO, and the influence mechanism of bacteria on the disappearance of CO is inferred. The research results and ideas provide reference for the accurate prediction of sealed goal.
