摘要 文章简要分析上层采空区积水情况、积水量及积水涌出方式,结合该矿巷道布设情况,对上层采空区积水进行探放,通过采取网格式放水、采空区压力减小区的长孔放水、长钻孔探水压、短钻孔放水、多孔、多点联合放水等多种放水方法,保证了安全回采,并总结出了该矿采空区积水的相关参数。 The paper briefly analyses the hydrops on the framing pieces of mined-out area,water accumulating volume and hydrop-flowing ways.Taking the roadway layout in mine into consideration,the exploration and discharge in the hydrops area will be made.The paper also mentions some drainage methods of detection,they are,gridding water discharge,longhole water discharge in less pressure area of mined-out area,water pressure discharge with long drill,water drainage with short drill and multi-drill drainage as well as multi-location drainage,which can ensure the mining safety.Furthermore,the paper provides the relavant parameters of the goaf hydrops of coal mine.
