预采疏放法防治首采工作面顶部含水层突水

THE METHOD OF DEWATERING DURING PRELIMINARY MININGFOR CONTROLLING WATER BURSTING FROM ROOF AQUIFER

新建矿井首采工作面突水是矿井生产后的首次大突水，其防治技术以往仅限于钻孔放水法，效果不佳。作者将“三带理论”用于生产实践，明确提出了顶部充水含水层包括煤层之上，离层带之下的所有含水层，首先开发了预采疏放法防治顶部含水层突水的技术。

The water bursting from preliminary face of new constructed mine is the first large scale water bursting since production.The controlling techniques was limited to hole dewatering,and its effect was not fine.The author combinedtheory of three zones with practice,presented that the flooding foof aquifers include all aquifers above coal seam and below separation layer.The controlling techniques using the method of dewatering was first developed by the author and very successful in Gaozhang Mine of Zaozhuang Mining Corporation,Shandong.
