底板岩巷穿层瓦斯抽采钻孔的优化布置
Optimization design of the cross-measure boreholes for gas pre-extraction in floor rock roadway
为了提高本煤层穿层钻孔的瓦斯抽采效果，采用COMSOL软件分别对阳泉矿区五矿8406工作面不同钻孔间距、钻孔直径、抽采负压条件下底板岩巷穿层钻孔的瓦斯抽采效果进行了数值模拟。研究结果表明：阳泉矿区五矿8406工作面穿层钻孔的合理布置间距为2～2.5 m，并且钻孔间距对穿层钻孔的瓦斯抽采效果影响显著，为工程实践提供了理论参考依据。
o improve cross-measure borehole gas extraction efficiency, numerical simulation was carried out at 8406 working face of the Yangquanwu coal mine under different borehole distance, diameter, and internal negative pressure by using COMSOL multi-physics software. The results show that the reasonable borehole distance of 2-2.5 m for 8406 working face is much more effective for gas extraction, which can provide theoretical reference for real engineering practice.
