摘　　要：为解决三交河矿一采区生产安全受相邻矿老空水的影响,研究决定在采区大巷中设置防水闭墙,设计运用规范、手册及力学相关公式,对防水闭墙的厚度、位置及强度进行计算。结合所选的混凝土强度和掏槽深度,以及闭墙所处巷道围岩力学参数,得出防水闭墙厚度为1.5 m,墙外侧壁距交岔口为3.5 m,强度满足要求。现场施工后防水闭墙稳定性良好,证实了设计方案的可行性,为该矿和其他矿井遇类似问题需设置防水闭墙提供了理论依据和技术支撑。In order to solve the problem that the production safety of No.1 mining area of Sanjiaohe Mine affected by goaf of the adjacent mine,it was decided to set up the waterproof wall in the main roadway of the mining area.The thickness,position and strength of the waterproof wall were calculated according to the design and application of the specifications,manual and relevant mechanical formulas.The selected concrete strength and cutting depth was combined with the mechanical parameters of the surrounding rock of the roadway.The results showed that the thickness of the waterproof closed wall was 1.5 m,the distance between the outer wall and the crossing was 3.5 m,and the strength met the requirements.After on-site construction,the stability of the waterproof wall was good,which proved the feasibility of the design scheme,and provided theoretical basis and technical support for the setting of waterproof wall in other similar mines.
