摘　　要：深井巷道开挖后,在矿山压力、水压及瓦斯压力等作用下,底板短时间内急速鼓起的现象,被称为急速底鼓现象。它是威胁矿井安全生产的一种新的底鼓形式,鼓出量大和底鼓速率快是急速底鼓的两大主要特征,也是其较难治理的原因。底板软岩的高围岩压力、水和瓦斯压力的综合作用是造成巷道发生急速底鼓的主要原因。对几个典型矿井发生急速底鼓的现象和原因进行了分析,为其治理提供了指导。After deep mine roadway excavation, under the action of ground pressure, water pressure and gas pressure, the rapid floor heave phenomenon in a short time is known as rapid floor heave phenomenon. It is a new floor heave form threat to mine safety produc- tion,large quantity and rapid floor heave are the two main characteristics of rapid floor heave,so it is difficult to control. The main rea- son of roadway occurs rapid floor heave is affected synthetically by high surrounding rock pressure of floor soft rock,water and gas pres- sure. Analysis on the phenomenon and cause of rapid floor heave occurred in some typical mines were made, provides guidance to con- trol it.
