黄陇侏罗纪煤田特厚煤层综放开采顶板水害防治技术

Prevention and Control of Roof Water Damage in Fully Mechanized Caving Mining of Super Thick Coal Seam in Huanglong Jurassic Coal Field

以郭家河煤矿1307工作面为例,总结已经回采工作面的顶板突水的规律,重点分析矿井顶板水害来源,采用物探与钻探相结合的综合探测方法,针对不同的水害类型采取相对应井上下钻孔疏排的防治水方法,消除了工作面回采期间的水害隐患,保证了工作面的安全生产。

This article takes 1307 working face of Guojiahe Coal Mine as an example, summarizes the laws of roof water inrush from the working face, focuses on the analysis of the source of water damage of mine roof. Comprehensive detection method combining geophysical exploration and drilling, for different water damage types, the method of preventing and controlling water by using the up and down drillings and drainage of the relative well is adopted to eliminate the hidden danger of water damage during the mining face and guarantee the safe production of the working face.
