摘要
在区域性防突技术中,通常采用"四位一体"防突预测,而在"四位一体"综合防突工艺中,关键是准确的预测预报。为了进一步防止无突出危险区突然升级,对煤层巷道掘进期间按突出威胁区进行管理,采用钻孔钻屑指标法和钻孔瓦斯涌出初速度法,对工作面的突出危险性进行预测验证。
In the regional outburst prevention technology, the outburst prevention forecast with ＂the four aspects in one＂ is applied. In the comprehensive outburst prevention craft with ＂the four aspects in one＂, the key is the accurate forecast. In order to further prevent the outburst warning area from promoting suddenly, the coal roadways is managed as the outburst warning area during driving. The face outburst danger is forecasted and checked by the drill hole and drilling target method, and the initial velocity method of drill hole gas outburst.
