李粮店矿井北风井二期工程,随着工程进展,掘进巷道距离北风井井底越来越远,进入高温地带,随着岩温增高及井下出水点流出的热水量增多,矿井高温热害逐步加剧,给矿井建设安全生产和职工身体健康带来严重威胁,为改善井下掘进巷道高温作业环境,采用局部制冷降温技术,井下安装TS系列煤矿井下局部制冷机组,进行矿井热害治理,解决了井下高温热害给职工身体健康带来的危害及对矿井建设安全生产带来的威胁。
With the progress of the project, the roadway heading further and further away from the borehole of the north wind shaft and into the high temperature zone, with the increase of rock temperature and the increase of the amount of hot water flowing out from the downhole water outlet, In order to improve the high-temperature working environment of mine roadway, using local cooling and cooling technology, underground series of TS series coal mine local cooling units are installed underground to carry out mine thermal harm treatment , To solve the harm caused by the high temperature heat damage to workers’ health and the threat to the safety of mine construction.
