淄博煤矿是我国底板水害比较严重的煤矿之一。在日本帝国主义侵略时期的1935年发生过著名的北大井淹井事故,每分钟水量竟达443吨的惊人数字,造成我国阶级兄弟535人死亡。日本人虽一度企图恢复该井,但因为技术上解决不了而作罢。据不完全统计,淄博矿区历年来共发生底板突水次数高达107次之多。随着开采深度的增大,底板突水的威胁也越来越大,不但影响到当前生产,而且还严重地威胁到矿井延深开拓工程的安全。因此,淄博煤矿的底板突水是一个迫切需要解决的大问题。
Zibo Coal Mine is one of the coal mines with relatively serious water hazards in our country. In 1935, during the Japanese aggression against Japan, the well-known Pei-Dong well-flooding accident occurred. The water volume per minute reached a staggering 443 tons, causing 535 deaths of our class brothers. Although the Japanese once attempted to restore the well, they could not give up because they could not solve the problem technically. According to incomplete statistics, a total of 107 water inrush times have occurred in Zibo mining area over the years. With the increase of mining depth, the threat of floor water inrush is also increasing, which not only affects the current production but also seriously threatens the safety of the deep mine extension project. Therefore, the floor water inrush of Zibo Coal Mine is an urgent need to solve the big problem.
