摘要
应用含瓦斯煤岩气固耦合模型(RFPA-GAS)系统对淮南远距离保护层开采进行了数值模拟,分析了采动过程中煤层上支承压力的分布规律以及采动过程对被保护煤层透气性的影响,用数值模拟方法分析了淮南远距离保护层开采卸压机理。
Having made a numerical simulation for remote protective layer mining by the RFPA - GAS system in Huainan mining area, and analyses the distribution law of abutment pressure over the coal seam while mining,the influence of mining on permeability of protected coal seam, and the destress mechanism for remote protective layer mining by numerical simulation ways in Huainan mining area.
