Floor Disturbance and Failure Characteristics of Super-Large Mining Height Working Face
The failure depth of the working face floor caused by mining is a key parameter to predict water inrush from the working face floor. Extensive research has been conducted on the floor failure zone of the working face. However, in recent years, there have been few studies on the floor failure law of the working face with a super-large mining height (over 20 m) in the western mining area of China. In this paper, the working face with a super-large mining height of 24 m in Longwanggou Coal Minedoi:10.1155/2022/1279642 fatcat:z34mdwgay5gltov745oeiezzjq
