高瓦斯突出矿井综采工作面U型通风瓦斯治理技术的研究

Study on Gas Control Technology of U-type Ventilation in Fully-mechanized Working Face of High Gas Outburst Mine

胡底煤业属高瓦斯突出矿井,综采工作面采用“U”型通风和高位钻孔与采空区埋管进行瓦斯抽采,杜绝了工作面上隅角及采空区瓦斯积聚现象,实现了工作面全年瓦斯零超限目标,确保了矿井安全生产。

Hudi Coal Industry belongs to a high gas outburst mine. High-level boreholes,buried pipes and U-type ventilation were used to extract gas on fully-mechanized working face to eliminate gas accumulation in upper corner and goaf, which has realized the goal of zero gas overrun on working face throughout the year, and has ensured the safety of mine production.
