由于井下水含有杂质,喷雾装置容易堵塞喷头。河南煤化集团王河煤矿采二队结合井下生产条件,把废旧5号钢管割成1米长,两端用铁板密闭,下端焊接三角铁架,以固定支撑钢管,并在铁架中间安装一个直径4厘米的阀门,以便使过滤器中的水流沉淀物及时排出。然后在钢管的左侧距上端0.4米处安装一个直径19毫米的进水阀门,右侧距钢管上 As the water contains impurities, the spray device is easy to plug the nozzle. Henan Coal Group Wanghe coal mining team combined with the underground production conditions, the No. 5 pipe scrapped into 1 meter long, both ends of the plate with airtight, the lower welded triangle frame to support the fixed steel pipe, and in the middle of a metal frame to install a diameter 4 cm valve, in order to timely filter out the water sediment discharge.
