埠村煤矿徐灰水特征及其防治措施分析

埠村煤矿有4个主要含水层,其中徐家庄石灰岩含水层组（简称徐灰水）和中奥陶系石灰岩含水层组（简称奥灰水）,对石炭系太原组煤的开采具有严重威胁。为研究徐灰水特征,详细分析了汛期对徐灰水和奥灰水水位的影响;设计了徐灰水放水实验,重点对放水实验过程中各钻孔水位的变化进行了统计分析。制定了徐灰水的防治措施,为石炭系太原组煤的安全开采提供了科学依据。

The Analysis about Characteristics of Xujiazhuang Limestone Water in Bucun Coalmine and Corresponding Prevention and Control Measures

There are 4 main aquifers in Bucun Coalmine, of which, the Xu limestone water （Xujiazhuang limestone aquifer group） and the Ordovician limestone water （Ordovician limestone aquifer group） are seriously threat to the coal mining in the Taiyuan Group of Carboniferous System. In order to study the characteristics of Xu limestone water,this paper firstly analyzes the influence of flood seasons on the levels of Xu limestone water and Ordovician limestone water in detail. Then, a water discharge experiment is designed, in which, statistical analysis about the changing of water levels in each borehole is made. Finally, the prevention and control measures of Xu limestone water were given. They can provide a scientific basis for the safety coal mining in the Taiyuan Group of Carboniferous System.
