| 摘 要： | 新汶矿业集团良庄煤矿51101W工作面因底板突水导致工作面被淹。通过水质分析,判定突水水源是奥陶系灰岩岩溶水。根据工作面附近的地质构造推断,突水通道为延伸到奥陶系与石炭系不整合面的铲状滑动断层(该断层最大落差只有7 m左右)。结合工程实践指出,在该矿,根据断层落差来判断断层导水性的观点并不正确,并提出了“用断层落差(H)与其倾角(α)之比值(S)来说明断层对突水影响程度”的观点。

| Abstract: | The water-inrush from floor inundates Working face 51101W in Liangzhuang coal mine,Xinwen Mining Group.Based on water quality analysis,it is judged that the source is Ordovician limestone.According to the structural characteristics,it is concluded that a spade shape fault,which extends the unconformity boundary between Ordovician and Carboniferous,and whose maximum fault throw is 7 m, is responsible the accident.Combined with engineering practicality,the view of judging water leading fault with fault throw is denied.It is suggested that using the coefficient (S) of fault throw (H) dividing fault incidence angle (α) shows the degree of a fault influencing water inrush. |
