【摘要】 我国煤矿床水害类型主要分为喀斯特充水煤矿床、砂岩裂隙充水煤矿床、第四系水及地表水充水煤矿床。其中喀斯特地区煤矿井是以岩溶水充水为主，由于喀斯特发育的不均匀性造成矿井充水具有不均匀、量大、突发性较强，并与大气降水密切的特点，矿井水害给煤矿生产安全生产带来的威胁也越来越大。新红林煤矿为一新建矿井，根据勘探成果，该井田未来充水水源来自上覆于可采煤层之上的含水丰富二迭系上长兴组及三迭下统夜郎组岩溶含水层，受岩溶发育控制，岩层中发育地下集中径流管道，地下水的补给不但有矿区范围内大气降水的补给，而且还有来自矿区外上游地表河流的转入，岩层含水极不均匀，地下水在含水层中集中径流，并且首采区处于井田内矿床主要充水含水层的地下水径流～排泄区，未来开采中矿井一旦沟通含水层，矿井涌水量大，甚至将在地下水集中径流管道地带产生突水，将是灾难性的、突发的、不可逆转的事故。该井田的矿床水文地质条件在我国同类岩溶地区煤矿山中具有较强的代表性。因此，通过分析新红林煤矿的充水水源和充水条件，采用解析法和泉流频率分析法预测新红林煤矿的涌水量，采用干扰井群法设计首采区主要含水层的疏干排水工程，拟编干扰井群条件下疏干排水的计算程序，调试并模拟计算矿区疏干排水工程的参数。提出水害防治的初步技术方案。对指导矿井进行安全生产，有重要的现实意义。同时，对贵州省乃至我国南方岩溶石山区类似条件下的煤矿山水害防治都具有重要的参考意义。更多还原

【Abstract】 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.更多还原
