采空区顶板“三带”研究在煤矿安全生产中的作用探析

Role of study on“three zones”of goaf roof in coal mine safety production

开展采空区顶板“三带”研究可为煤矿安全开采设计及防控灾害风险提供重要的技术支撑和依据,对煤矿安全生产具有重要的现实作用和意义。结合工作实践,以开展“三带”研究工作的必要性为目的,探讨了“三带”研究的主要内容及相关技术方法。分析了“三带”研究在煤矿安全生产中的重要作用,认为“三带”研究的作用主要体现在高位瓦斯抽采关键层位优选、预防顶板水害防隔水煤(岩)柱确定、顶板控制及地质预测预报等方面提供基础技术参数和依据,并提出了“三带”研究注意事项及改进建议,为深入“三带”研究提供了一定参考。

Research on the“three zones”of goaf roof can provide important technical support and basis for coal mine safety mining design and disaster risk prevention and control.Based on work practice and the necessity of conducting study on the“Three Zones”,this paperexplores the main content and related technical methods of the“Three Zones”research,analyzes the important role of the“Three Zones”research in coal mine safety production,and believes that the role of the“Three Zones”study is to provide basic technical parameters for selection of the high-gas key stratum for extraction,determination of the diaphragm coal(rock)pillar for preventing water hazard,and roof control and geologic forecast.Some improvement suggestions on the“Three Belts”research are proposed,providing some reference for deepening the“Three Belts”research work.
