The Feasibility of Multi-seam Ascending Mining in a Mine

摘要：

　　No.7 and No.8 are the mainly explored coal seams with good quality and large reserves,and have great mining value.To determine the feasibility of ascending mining,the research was carried out based on a combination of theoretical calculation and numerical simulation approach analyzes distance between caving zone height of No.8 layer and caving zone borders on the top and bottom plate of No.7 coal seam,and determine the feasibility of mining No.8 layer.
