浅孔煤体快速注水研究应用

The shallow bore coal notes the water research quickly application

随着矿井开采深度的增加,煤层承受的压力也不断增加,深孔煤体注水在钻眼过程中,常常出现夹钻、塌孔等现象,无法达到预计孔深,导致无法正常注水,注水效果差。通过在采掘过程中直接快速浅孔煤体注水,可增加煤体内水分,有效减少爆破或机组割煤时的煤尘飞扬,对预防煤尘爆炸、保护职工身心健康起到重要的作用。

Mine the increment of the depth along with the mineral well, the pressure that coal seam bear also increases continuously, the deep bore coal notes the water in drill eye process, usually appearing to clip to drill, fall bore etc. phenomenon, canting attain to anticipate the bore deep, cause cant normal note the water, note the result of water bad. Pass in digging process the direct fast shallow bore coal notes the water, loan increase the coal internal water divide, the valid decrease blows up or the machine a coal for mowing coal hour floats in the sky, explode, protecting the officers and workers to the prevention coal the mind and body health rises important function.
