泊里矿煤层底板突水危险性分析与防治措施研究

Study on the risk analysis and prevention measures of coal seam floor water inrush

泊里矿煤层受到底部灰岩岩溶高承压水的突水威胁日趋严重,采用传统的突水系数法评价煤层底板奥灰突水危险性已不能作为矿井安全生产的依据。本文对煤层底板奥灰含水层带压情况进行了分析,通过对煤层底板突水机理及突水危险性分析研究,提出了煤层底板奥灰突水的防治措施及建议,为泊里矿煤层的安全开采提供了技术支持和科学依据。

The water inrush threat of the limestone karst with the high water pressure under the bottom of coal seam in Bo Li coal mine is becoming more and more serious, the water bursting risk of ordovician limestone determined by the traditional evaluation of water inrush coefficient is not as a basis for safe production in coal mine. In this paper, the coal seam floor aquifer pressure were analyzed, through the analysis of the floor water inrush mechanism and the water inrush risk, the prevention measures and suggestions for water bursting were put forward, which provide technical support and scientific basis for the safe mining of Boli coal mine.
