煤层底板灰岩赋存大量瓦斯且情况复杂,使得瓦斯喷孔事件造成的瓦斯超限事故严重威胁正常工作生产。为了深入了解煤层底板灰岩瓦斯赋存情况,采用Fluent模拟软件模拟失踪气体探测潘二矿1煤底板灰岩的连通性及岩溶发育情况,根据接收的SF6气体时间与流量,确定现场灰岩空间以及漏风通道的分布情况,分析影响灰岩中瓦斯赋存的主要因素。%Limestone under coal floor has a large number of gas and the situation is complex. The gas exceeding accidents caused by gas orifice lead to serious threat to normal production work. To better understand the gas situation in limestone under coal floor, the pa- per determined limestone space and distribution of air-leakage passage, analyzed the main factors of gas in the limestone using the Flu- ent simulation software to simulate missing gas and detect limestone connectivity and the development of karst under coal floor, accord- ing to the received time and gas flow of SF6.
