摘要
针对韩家湾煤矿三盘区富水性中等有突水危险的问题,为了安全有效地开采2^(-2)煤层,以地下水动力学为基本原理,建立了以渗透破坏的临界水力坡度为条件的预防突水溃砂发生的临界条件和预计公式,计算得出了该矿预防突水溃砂发生的临界水压的高度,为韩家湾煤矿制定矿井防治水工程方案提供理论依据。
According to the rich medium water inrush danger problems of rich water in No. 3 mining block of Hanjiawan Mine, in order to safely and effectively mine No. 2 -2 seam, base on the basic principle of the underground water dynamics, a critical condition and predicted formula of the prevented water inrush and sand inrush occurred were established with the condition of the permeated failure critical hydraulic slope. The height of the critical water pressure to prevent the water inrush and sand inrush occurred was calculated, which could provide the theoretical basics to set up the mine water prevention and control project plan of Hanjiawan Mine.
