浅谈斜井施工中揭煤防突技术方法应用

Discussion on the Application of Technology of Uncovering Coal and Preventing Outburst in Inclined Shaft Construction

永安宏泰煤业副斜井施工揭穿煤层过程中,采用钻屑瓦斯解吸指标法、瓦斯含量法检验了瓦斯突出危险性,在准确预测揭煤突出危险性的基础上,综合考虑了施工中开挖方式、爆破、通风等方案,采取安全技术防突措施,保障了井筒安全、快捷地穿过煤层,取得了良好的效果。

In the process of uncovering coal in vice inclined shaft construction of Yongan Hongtai Coal, the gas desorption index of drill cuttings method and gas content method were used to test gas, considered the schemes of excavation method, blasting and ventilation with the accurate prediction of outburst danger in uncovering coal, and took safety technological prevention measures, which ensured the well bore to go through the coal seam safely and quickly, and achieved good results.
