煤与瓦斯严重突出危险区综合防突技术探索

Disussion on the Preventive Methods for SeriousCoal and Gas Outburst in Certain Region

２１０７１工作面是六矿突出危险性最严重的地区．为防治工作面煤与瓦斯突出，六矿采取了瓦斯地质编图预测预报、预抽瓦斯降低瓦斯含量及压力、搞好点预报与临时防突措施等全方位的瓦斯防治方法，缓解了采掘接替紧张局面，取得了较好的防突效果．

In order to prevent the serious coal and gas outburst at 21071 stope and keep a safety working condition,some methods were adpoted by using the drawing of gasgeology map to predict methane drainage and cut down the gas content and pressure.The point forecast and temporary measures have been performed to control the outburst for the improvement on the mining process.
