摘　　要：结合兖矿集团有限公司开采山西组3#煤时的涌水资料,研究总结出影响3#煤上覆岩层涌水的相关因素和涌水规律,3#煤上覆岩层涌水强度与开采区域(新开采区和浅埋区)、构造发育状况、矿压显现及工作面开采厚度、推进速度密切相关;上覆岩层涌水往往来水突然、来势猛、水量大,并且具有近似周期性变化的特点。同时总结提出多条具体的3#煤上覆岩层水防治措施,为类似条件开采水害防治提供借鉴。According to mine water gushing data of the No. 3 coal in Shanxi formation from Yankuang Group, the study summarized relevant factors and water gushing laws from overlying strata of No. 3 coal in Shanxi Formation. The water gushing strength has relation to mining area （new mining areas and shallow buried areas） , structural development status, strata behaviors, the thickness of the mining face, and workface advancing rate, etc. Water gushing from overlying strata, runoff sudden, fierce and large amounts of water, has the features of approximately periodical trend change. The study summarized specific prevention measures to control water gushing from overlying strata of No. 3 coal, which can provide certain reference for water gushing controlling for the mines with similar mining conditions.
