以汾源矿5#煤底板施工注浆钻孔资料为基础,分析了汾源矿奥灰原始导高发育情况及其对煤层开采的影响,得出汾源矿奥灰上马家沟组顶面存在9.1~49.25 m的原始导高;5-101首采面部分区域奥灰原始导高可发育至底板破坏带以上,首采工作面回采存在一定的奥灰突水危险,对5-101工作面进行底板隔水层注浆加固及含水层改造可起到防治水作用,并且对发育有奥灰原始导高的矿井防治水工作也有一定的指导意义。
以汾源礦5#煤底闆施工註漿鑽孔資料為基礎,分析瞭汾源礦奧灰原始導高髮育情況及其對煤層開採的影響,得齣汾源礦奧灰上馬傢溝組頂麵存在9.1~49.25 m的原始導高;5-101首採麵部分區域奧灰原始導高可髮育至底闆破壞帶以上,首採工作麵迴採存在一定的奧灰突水危險,對5-101工作麵進行底闆隔水層註漿加固及含水層改造可起到防治水作用,併且對髮育有奧灰原始導高的礦井防治水工作也有一定的指導意義。

On the basis of No.5 coal seam floor injection grouting drill hole data in Fenyuan coal mine,analyzes the ordovician limestone initial water level and the influence to coal seam mining.It obtains that at the top of Shang-majiagou group existing 9 .1 ~49 .25 m initial water level.The ordovician limestone karst initial water level can up to floor damage zone of 5 -101 first mining face partial region,so the first mining face has water inrush danger.Floor aquiclude grouting reinforcement and aquifer reform have important effect for water prevention and control,it also has a guiding significance for the mine water prevention and control of that threaten by the ordovician limestone initial wa-ter level.
