摘要
从水量、水温等方面对新集一矿111311工作面异常突水和突水机理进行了分析。认为该工作面突水水源主要为17#煤层顶板砂岩水、F038断层和附近裂隙充水以及少量13#煤层顶板砂岩水。
Analysis was made on the abnormal water inrush and water inrush mechanism in No. 111311 working face according to water quantity and temperature and a conclusion was drawn that the water inrush in this face mainly came from the water in roof sandstone of No. 17 coal seam,the water in F038 fault and fractures around it,and a small amount of water in roof sandstone of No. 13 coal seam.
