| Coal deposit flooding injury style mostly divided into karst fill coal deposit, sandstone crevice water filled coal deposit, quaternary system water and surface water filled coal deposit. It is karst water filled give priority to karst region colliery best.Owing to karst developmental offset wrought shaft water filled nonuniformity, quantity outburst larger, stronger, combine with atmospheric precipitation intimate . Flooding injury threat to mine produce safety in production more and more heavy.Xinhonglin coal mine is a newbuild shaft, according to exploration results, borefield water filled fountainhead in the future come frome containing water or moisture exuberance of karst aquifer bespread to upper of workable seam, be subjected to karst upgrowth control in the middle of rock formation upgrowth underground foci runoff conduit, groundwater supply have ground surface stream besides camp and atmospheric precipitation of camp precinct, rock formation containing water excessively nonuniformity. Groundwater foci runoff at the middle of aquifer. head division exist in groundwater runoff～discharge area of deposit mostly water filled aquifer. Shaft once communicate aquifer in the future of exploitation, will be disastrous, gusty, irreversible accident. The deposit geohydrologic condition of the this borefield possess stronger representativeness in uniformity karst region coalmine.It through analyses Xinhonglin coalmine's water filled fountainhead and water filled condition, to forecast inflow of water of the Xinonglin coalmine, bring up introduction technical proposal for flooding injury prevention and cure. It have important actual meaning to supervise shaft proceed safety in production.At the same time, it hase important reference sense to Guizhou province and even to south of south country's karst section of similar conditions coalmine flooding injury prevention and cure. |
