结合余吾煤矿自动放水装置满足不了放水量要求,并且容易积水积尘的实际情况,通过分析现用的浮子式储水箱负压自动放水器在工作过程中遇到的问题,提出了合理易行的改进方法,以进水漏斗和蓄水管作为进水、储水装置,采用增大放水口径的方法对放水器进行技术改造,实现了大容量放水,解决了瓦斯抽放管路积水积尘问题,并通过现场应用,取得了良好效果。
Based on the actual situation of YuWu coal mine automatic drainage device can not meet the requirements of water discharge and easy to accumulate water and dust, the paper analyzes the problems encountered in the working process of the present automatic submersible water drainer with float water tank, , The water funnel and the water storage pipe are taken as water inlet and water storage devices, the water diversion device is improved by adopting the method of increasing the water discharge caliber, the high-capacity water discharge is realized, the water accumulation in the gas drainage pipeline is solved Dust problem, and through the field application, and achieved good results.
