| 摘 要： | 承压水上采煤的关键问题是煤层底板是否能有效地阻止底板高压水突出。底板突水与否取决于多方面影响,其中最重要的是煤层底板条件。下三带理论为分析、评价底板抗突水能力提供了理论指导。依据“下三带”理论,探讨了承压水上采煤安全性评价的方法与技术。

| Abstract: | The key of the coal mining above confined aquifers is to understand the water-resistion ability of the coal seam floor.Many actors have influence on water inrush from the floor,of them the geological conditions of the floor are the most important.The "down-three-zone"theory provides theoretical foundation for security evaluation.Based on that this paper presents a set of methods and technology to evaluate security of the coal mining above the confined aquifers. |
