瓦斯抽排孔最佳孔位设计研究

 摘 要：本文从岩层移动和变形特征的角度提出了瓦斯抽排孔设计的最佳三角形区域，并以淮南某矿地面抽排孔抽采数据为依据，通过分析其实际孔位与抽排效果之间的关系，总结出实际最佳抽排孔位置，并与提出的最佳三角区作对比，判断分析设计是否正确。该设计方法可以得到每个抽排孔所能控制的瓦斯排放区域以及其合理设计密度，为日后抽排孔设计提供了有力的指导作用，同时节省钻孔开支，提高瓦斯抽采效益。

The Optimization Hole Positon Design Of Gas Drainage

Abstract: This article put forward the optimized triangle area for gas drainage/releasing hole design from the point of rock movement and deformation characteristics; and according to surface drainage hole of a mine in Huainan extraction data, analyzed the relationship between actual holes positions and the drainage effect, summarized actual optimized drainage hole position and compared with the best triangle put forward to analyze and check if the former design is correct. The design method can get the gas drainage area controlled by each releasing hole and its reasonable design density, so this method can support future drainage holes design and save drilling costs and increase gas extraction efficiency.
