摘    要:随着煤矿开采深度的不断增加,矿井突水事故日趋增多。陈四楼煤矿的2517工作面回采期间受邻近工作面老空区动水影响,对安全生产影响较大。通过综合分析,确定了通过施工挡水墙将动水引流至巷道的方案,并根据相关设计规范合理确定了挡水墙的厚度等结构参数,成功施工了挡水墙。2517工作面已安全回采,挡水墙引流效果明显,达到了工程设计的要求。

关 键 词:老空区  动水  挡水墙引流  工作面  水害  防治水

Abstract:With the increase of mining depth,the water inrush accidents are increasing day by day. In the process of coal winning on 2517 face of Chensilou Coal Mine,the dynamic water of gob on adjacent faces has seriously affected the safe production of coal mine. Through comprehensive analysis,the scheme of drain gob water to roadway by constructing water retaining wall was determined,meanwhile,structure parameters of water retaining wall,such as thickness,and so on,were also determined reasonably according to the relevant design specifications,in the end,the water retaining wall was constructed successfully. All this has realized the safe coal winning of 2517 face,and the effect of water drain is well,and has fulfilled the demand of engineering design.
Keywords:mined-out area  dynamic water  drainage water retaining wall  working face  water hazard  water control
