摘要
通过对安顺煤矿9102工作面防突技术的研究,采用地下抽采技术布置并利用突出敏感指标(钻孔瓦斯涌出初速度q、钻屑量S、钻屑量解吸指标K1值(或Δh2)等)进行消突验证,得到常规的瓦斯治理井下抽采和突出敏感指标相结合的瓦斯治理新思路,对同类矿井瓦斯治理具有借鉴意义。
In anshun coal mine 9102 working face of outburst prevention technology research, the underground extraction technology layout and use the outstanding sensitive index （ at the beginning of borehole gas emission rate q, drilling cuttings measure S, cuttings desorption index values of K1 （ or △h2 ）, etc. ） carried away a validation, gas control downhole receiving regular extraction and highlight the sensitive index of combining the gas control new way of thinking, the significance of reference to the similar mine gas control.
