    Water inrush characteristics and hazard effects during the ,, 1 Introduction Iron ore, being one of the most important industrial raw materials, is exploited and consumed in large quantities in many industries, and its usage is increasing every year [1,2]The open-pit mining method is generally preferred in mining activities due to its extensive applicability to various kinds of exposed rock, its minimum production loss and its high production rate ,Basics of an open pit mine, Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal
