摘要

为在突水发生后快速判断突水通道类型,提出通过突水量演化特征识别煤层底板突水通道的方法。依据煤层底板构造发育情况及其与采掘活动的空间关系,将煤层底板突水通道划分为完整底板通道、非贯通型通道及贯通型通道3种类型。分析了3种类型突水实例,获得了不同突水通道煤层底板突水水量演化特征。再依据水量演化特征的煤层底板突水通道识别方法,凭峰前突水量演化及峰后水量衰减特征,判断突水通道类型。且采用三维相似模拟平台,模拟了1例岩溶陷落柱突水过程。结果表明:该次突水通道为贯通型通道,与突水通道识别模型分析结果一致,不同突水通道具有显著的突水量演化规律差异,水量演化特征能够较准确地反映突水通道的演化过程。
In order to rapidly judge the type of the water inrush channel,according to the structure development condition of the seam floor and the space relationship between the mining and driving activities,the water inrush channel of the seam floor was divided into a completed floor channel,non running through type channel and running through channel.The three type water inrush cases were analyzed and the quantity evolution features of the water inrush from seam floor with different water inrush channel were obtained.Based on the quantity evolution features,the method to distinguish the water inrush channels in the seam floor was provided and based on the water inrush evolution before the peak occurred and the water quantity attenuation features after the peak occurred,the water inrush channel type was judged.A3 D similar simulation platform was applied to simulate a water inrush process of a karst sinkhole.The results showed that this water inrush channel was a running through channel,was the same to the analysis results of the water inrush distinguishing model,the different water inrush channel would have obvious differences of the water inrush quantity evolution law and the water quantity evolution features could accurately reflect the evolution process of the water inrush channel.
