针对神东矿区采煤工作面回风隅角出现CO超限问题,在调研及现场观测的基础上,认为神东回风隅角CO来源主要是由于采空区浮煤氧化、采煤机割煤破碎煤体,胶轮车尾气产生,其中采空区浮煤低温氧化是主要来源。为采取合适的超限控制技术措施提供了依据。 In view of the CO overrun problem at the return air corner of coal mining face in Shendong Coal Mining Area, based on the investigation and on-site observation, it is considered that the source of CO in the Shen-Dong return air-horn is mainly due to the floating coal oxidation and shearer cutting Coal broken coal, tire rubber tire production, of which goaf floating coal low temperature oxidation is the main source. In order to take the appropriate technical measures overrun control provides the basis.
