摘要
10煤为童亭矿主可采煤层之一,其下太原组灰岩对10煤层开采存在潜在的突水威胁。疏水降压作为底板灰岩水害防治的重要技术途径之一在童亭矿107采区成功使用,对107采区的疏放工程进行了认真总结,对疏水降压前后的开采安全性进行了分析评价,对指导类似条件矿井的防治水工作有一定的借鉴意义。
No. 10 coal seam is one of the main minable coal seamin in the Tongting mine, menaced by limestone water bursting of Taiyuan Group in the mine exploitation. Drainage and decreasing pressure is one of key technologies the of coal floor limestone water damage control, used in No. 107 mining area successful. This paper summarizes draining project of No. 107 mining area, analysis and evaluated security of mining before and after drainage and decreasing pressure. The result has referential significance to mine water prevention of the similar mine.
