摘要: 为避免山西临汾胜利煤矿10号煤层采动过程中受上覆6号煤层采空区透水的威胁，利用板壳理论、断裂力学理论分别建立导水裂隙带高度和底板破裂深度的力学模型，计算10号煤层Ⅰ—Ⅵ区开采过程中导水裂隙带高度分别为46.77 m、48.86 m、56.05 m、56.14 m、56.33 m和55.20 m，6号煤层Ⅰ—Ⅳ区的破裂带影响深度分别为1.57 m、1.14 m、1.85 m和1.26 m。通过构建上覆煤层采空区积水危险性类型的划分准则，对10号煤层采动过程中受到上覆6号煤层采空区积水的危险性进行判定分析，结果表明：6号煤层Ⅰ—Ⅳ区对10号煤层的积水危险性类型均为突水型，会对10号煤开采过程产生安全威胁；6号煤层的不可采区域对10号煤层Ⅴ区和Ⅵ区的影响类型为原岩渗透型，对10号煤层Ⅴ区和Ⅵ区的回采不会构成危险性。Abstract: In order to avoid the threat of water penetration from the goaf of overlying seam No.6 during mining seam No.10 in Shengli coal mine of Linfen, Shanxi, plate-shells theory and fracture mechanics theory were used to establish the mechanics model of the development height of water-conducting fissure zone and the rupture depth of the floor. The water conducting fissure zone developmental height in districts I-VI of coal seam 10 is 46.77 m, 48.86 m, 56.05 m, 56.14 m, 56.33 m and 55.20 m, and the rupture zone depth of the floor in districts I-IV areas of coal seam 6 is 1.57 m, 1.14 m, 1.85 m and 1.26 m. By structuring criteria for water accumulation risk classification of overlying goaf and to determine the risk of accumulated water in the goaf of coal seam 6 during the mining process of coal seam10, the determination result shows that the water accumulation risk in districts I-IV areas of coal seam 6 is of the type of water inrush for seam 10, and would threaten the mining of coal seam10. The influence of the unminable area of seam 6 on the districts V-VI of seam 10 is of permeability of primary rock, and wouldn't threaten the coal extraction in the districts V-VI of coal seam 10.
