摘要
本文对北方煤矿床充水条件的研究,是在区域构造格架、含水层沉积和富水性变化规律、岩溶发育空间特征等的基础上,将矿区置于岩溶水系统中进行分析。在划分的91个岩溶水系统中,52个有煤矿区分布,从矿区所处的岩溶水系统的天然资源量和在系统中的部位,可大致判断矿区的富水性。再进一步分析岩溶水进入矿井的条件,并与矿井排水量、突水量、突水频率等实际和预测资料相印证。最后,统筹考虑区域指标、勘探指标和矿井指标,划分出12个岩溶水害类型,以便针对不同的类型,采取不同的防治对策。
The purpose of the research on water charge conditions of coal deposits in North China is to study the mine areas with a Karst water system based on the framework of regional tectonics, sedimentation of aquifers and rules of change of wateriness, spatial features of the development of Karst. In the 91 Karst water systems, coal mines are found in 52 Karst water systems. And wateriness of coal mines can be roughly determined by the quantity of natural resources, and their position in the Karst water system.And then investigation is made to find out conditions for the Karst water to enter the mines and the predicted data are compared with the actual mine water discharge, inrush frequency and quantity. Finally, the regional index, exploration index, and mine index are determined as a whole, 12 types of seams are considered as being threatened by Karst water inrush and counter measured will be akin to prevent water inrush in different coal seams.
