摘要
大埋深老空积水是矿井重要危险源,探放过程中存在塌孔等因素影响。综合利用矿压、材料力学等方面知识,合理确定探水"三线"、钻孔设计方案,控制不利影响因素,实现了探放水工作安全实施。
The gob water with large buried deep is the important dangerous source of mine, and the holes easy collapse in the process of exploration and drainage. We use the knowledge of mine pressure, material mechanics, reasonably determine the water ＂three line＂ of exploration, the borehole design scheme, control the adverse factors, and realize the safety of water release work.
