摘要
矿井水害是影响煤矿安全生产的主要危害之一,为了加强煤矿防治水能力,确保煤矿的安全开采,依据"物探先行、钻探验证"的煤矿防治水执行标准,以正珠煤业井田为研究对象,通过采用瞬变电磁法探明了物探异常区 15J-1,给钻探提供靶区,减少了钻探工程量,提高了钻探精度,消除了安全隐患.通过使用各种手段对异常区进行验证,明确了15J-1 物探异常区为 15#煤层实煤区,平均煤厚为 5.2 m,地质条件简单,整体为单斜构造,无采动破坏区,无水害隐患.
Abstract
Mine water damage is one of the main hazards affecting coal mine safety production.In order to strengthen the ability of coal mine water prevention and ensure the safe mining of coal mines,based on the implementation standards of"geophysical exploration first and drilling verification"for coal mine water prevention and control,this paper took Zhengzhu Coal Mine as the research object,and used transient electromagnetic method to explore the abnormal geophysical area 15J-1,providing a target area for drilling,reducing the amount of drilling work,improving drilling accuracy,and eliminating safety hazards.By using various means to verify the abnormal area,it is determined that the 15J-1 geophysical anomaly area is the actual coal seam area of the 15#coal seam,with an average coal thickness of 5.2 m.The geological conditions are simple,and the overall structure is monoclinic,without mining damage areas and water hazards.
