崔木煤矿顶板涌突水类型及其判别研究
|
摘要
崔木煤矿在生产过程中主要受顶板水害的严重威胁,由于顶板涌水特征复杂且难以预测,造成防治难度较大。为保障矿井安全生产,通过大量现场实测数据的统计分析,采用含水层水位响应时间,结合突水位置、瞬时水量大小、水量变化速率及涌水水质特征等判别参数,将顶板涌突水划分为静储量释放和离层突水2类;通过判别发现崔木煤矿顶板水害以离层突水为主,利用判别参数还可对顶板涌突水进行初步的预测。
Roof water disaster was the most serious threat to mining activities in Cuimu Mine, and it had multiple features which made it hard to predict and control. In order to ensure the safety of mine production, through the statistical analysis of a large number of field measured data, the response time of aquifer water level was adopted, and combined with the location of water inrush, instantaneous water quantity, water change rate and water inrush quality characteristics and other discriminating parameters, the roof water inrush was divided into two categories: static reserve release and separation layer water inrush. It is found that the roof water damage in Cuimu Coal Mine is mainly caused by water inrush from separate layers, and the roof water inrush can be predicted preliminarily by discriminant parameters.
