【摘要】 松宜矿区九对矿井中的四对最大涌水量超过5000m~3/h,矿井之间水力联系密切,明显处于同一地下水系统之中。本文以防治水为目的,应用系统理论对该区地下水系统进行了分析,建立了地下水系统概化模型、防治水优化管理模型,绘制了地下水系统网络图及相应的防治水网络图。文中强调了地下水系统的整体性、层次性、目的性及相互联系。更多还原

【Abstract】 There are four mine wells in Songyi mine area, in which the maximum daily dewatering is beyound 5000 cubic meters perhour. Although several ten millions Yuan has been invested in the water prevention and control since 1980, the hydrogeological problems are still serious. Draining incidents occured for six times and water gushing in the mine is still not decreased. There are two main reasons for that, i.e. (a)the hydrogeological condition, particularly those of the whole groundwater basin, is not really recognized. Formerly, explorations and analyses are mainly focused on single well field; (b) the systematic sense was neglected during the water preventing process. More attentions were only paid to trying to plug solitary hole on the surface and in the wells.Aiming at water control, systematic theory is applied here to analysis the hydrogeological condition of the whole groundwater basin.A model and a network diagram of the groundwater system are presented, which are very useful to resolve the mine water problems in the area.In the model, the"draining of mainly"is used instead of the previous "pluging mainly". The diagram not only reflects distinctly the construction of the groundwater system, but also makes the way of water prevention being clear at a glance. In addition, a network diagram of water control is built up, and an optimum management model is developed with an object at the minimum cost. In the paper emphasis have been placed on the interrelation of wells and holes and the whole effectiveness of water control.更多还原
