| 摘 要： | 破裂构造网络是渭北煤田奥灰岩溶裂隙水赋存的主要空间。正确认识网络系统中具有储水功能的通道及其连通性是掌握奥灰水赋存规律的关键。本文在总结区内构造网络特征的基础上,通过构造演化阶段的分析,指出了经过最末一期构造作用后延伸远、切割深并表现为张性或张扭性质的破裂构造,是奥灰水储集和运移的主要通道,也是煤矿生产中最易发生突水事故的破裂构造。

| Abstract: | The Fault-fracture network is the main space of accumulating karst-fissure water in the Ordovicion limestone of Weibei coalfield.It is the key to understand the law of water accumulation to recognize correctly the passageways for accumulating the water and their connecting characteristic in the network system. Based on the summary of characteristic for structural network in the region, and the analysis of tectonical evolutionary stage, author points out that the fault-fracture structure of spreading, deep cutting and tensile or tensile-wresflc are the main passageway of the water accumulation and movement after they have involved in the last tectonic movement.the accidnet of mine influx occures very easily in the fault-fracture structures. |
