摘　　要：煤矿防治水工作在矿井生产过程中起着重要的作用,煤矿防治水工作开展的好与坏直接关系到国家财产和人民生命安全,关系到社会稳定和谐发展。晓明矿作为一个生产50余年的老矿井,井田范围内存在大量老空区。北二7#煤层老空区由北二709、北二710、北二711、北二722和北二723五个老空区组成,老空面积广,可存水量大,积水情况复杂,通过北二802工作面对采空区积水进行探放,查明积水量、积水范围及各老空区之间的水利联系,保证综采工作面的顺利回采,为以后老空水的探放提供丰富的经验。Water prevention and control work in a coal mine plays an important role in the process of mining.The quality of coal mine water prevention and control work is directly related to the safety of national property and people's lives,and is related to social stability and harmonious development.As an old mine that has been in production for over 50 years,Xiaoming Mine has a large number of old goafs within its mining area.The goaf of Bei'er#7 coal seam is composed of Bei'er 709,Bei'er 710,Bei'er 711,Bei'er 722 and Bei'er 723,which has a wide empty area,large water storage and complex water accumulation.Through the exploration and discharge of stagnant water in goaf through the work of Bei'er 802,the water accumulation,the scope of water accumulation and the water conservancy connection between various goaf are found out,which ensures the smooth mining of fully mechanized mining face and provides rich experience for the exploration and release of old empty water in the future.
