摘要： 结合沙曲矿瓦斯易超限的实际，对裂隙带高位钻孔进行合理布置，采用ADR-250型大孔径钻机施工，并进行
抽采。试验结果表明：钻孔高纯量抽采步距可达90 m，抽采效果明显，解决了瓦斯超限。

Abstract: There is an actual situation that gas is easily to overrun in Shaqu Coal Mine, reasonable arrangement was carried out
in highly-located borehole in fractured zone, and ADR-250 type large aperture rig construction was adopted to perform exhausting
and mining. The results showed that: the amount of high-purity drilling drainage pitches was up to 90 m, drainage effect was
obvious, and the gas overrun problems were solved.

Key words: ADR-250 drilling machine; large aperture; gas drainage; drilling arrangement
