METHOD FOR WETTING COAL BED

摘要

A method that includes well drilling, sealing of those and supply of working liquid under pressure to the bed is realized in stages, by wells with varying length and depth of sealing. Length of wells and depth of sealing those is determined by placement of zone of maximum of abutment pressure from cleaning working by maximal rubble output at each section of the well at drilling. The length and depth of well sealing is corrected in such way that sealing depth is not less than depth of section with maximal rubble output. This makes it possible to increase effectiveness of wetting and promotes decrease of dust-gas formation at carrying out of mining operations.
